1 00:00:06,240 --> 00:00:10,000 Speaker 1: Welcome to Creature feature production of iHeartRadio. I'm your host 2 00:00:10,080 --> 00:00:15,080 Speaker 1: of Many Parasites, Katie Golden. I studied psychology and evolutionary biology, 3 00:00:15,120 --> 00:00:18,080 Speaker 1: and today on the show we are getting guy and 4 00:00:18,160 --> 00:00:22,119 Speaker 1: you can see we are talking about animal immune systems 5 00:00:22,520 --> 00:00:26,439 Speaker 1: now as we hopefully exit the cold and flu season. 6 00:00:26,480 --> 00:00:29,840 Speaker 1: I'm sure a lot of you have had some recent 7 00:00:30,000 --> 00:00:35,919 Speaker 1: experience with your immune system, and despite how unpleasant it is, 8 00:00:36,000 --> 00:00:40,919 Speaker 1: it is also really fascinating. So today is a special 9 00:00:41,000 --> 00:00:44,320 Speaker 1: episode because I have a guest who is a naturalist, 10 00:00:44,400 --> 00:00:48,960 Speaker 1: a teacher, and an author whose recent book, Sick is 11 00:00:49,000 --> 00:00:54,320 Speaker 1: about amazing stories of the animal immune system. It would 12 00:00:54,320 --> 00:00:58,280 Speaker 1: be a book that if I had got my hands 13 00:00:58,360 --> 00:01:01,160 Speaker 1: on this book when I was a kid, it would 14 00:01:01,200 --> 00:01:04,839 Speaker 1: be like my personal Bible. Is it is really fun 15 00:01:05,120 --> 00:01:08,120 Speaker 1: even for adults. Welcome Heather Montgomery. 16 00:01:08,760 --> 00:01:11,080 Speaker 2: Hey, I'm so excited to be here and talk to 17 00:01:11,120 --> 00:01:14,120 Speaker 2: folks who are just as excited as I am to 18 00:01:14,240 --> 00:01:17,080 Speaker 2: learn from the animal world. It's so amazing what's out there. 19 00:01:17,120 --> 00:01:19,840 Speaker 2: If we open our eyes and start asking questions. Wow, 20 00:01:20,200 --> 00:01:21,520 Speaker 2: I just get carried away with it. 21 00:01:22,680 --> 00:01:26,160 Speaker 1: I feel like we're very much kindred spirits. Because I 22 00:01:26,200 --> 00:01:29,960 Speaker 1: love the grossness of biology Obviously, I do love a 23 00:01:30,000 --> 00:01:34,080 Speaker 1: beautiful butterfly. I love a beautiful bird, but I think 24 00:01:34,400 --> 00:01:38,600 Speaker 1: I also enjoy appreciating just the you know, the poop 25 00:01:38,720 --> 00:01:42,959 Speaker 1: of nature. It's so interesting and it's I mean, it's 26 00:01:43,200 --> 00:01:47,520 Speaker 1: not only a great way to I think teach kids 27 00:01:47,560 --> 00:01:49,640 Speaker 1: about it, because like, you know, you got to lean 28 00:01:49,680 --> 00:01:51,560 Speaker 1: in a little bit to like the gross stuff to 29 00:01:51,600 --> 00:01:55,280 Speaker 1: get kids interested. But honestly, I also believe that is 30 00:01:55,320 --> 00:01:57,560 Speaker 1: true of adults. Like we may not like to admit it, 31 00:01:58,080 --> 00:02:02,680 Speaker 1: but I certainly have never outgrown learning stuff about poop 32 00:02:02,760 --> 00:02:06,600 Speaker 1: and fighting. It both kind of funny and really interesting. 33 00:02:06,680 --> 00:02:09,360 Speaker 2: Right, isn't that funny that happens? Like when we grow up, 34 00:02:09,400 --> 00:02:12,000 Speaker 2: we're supposed to not be interested in the things that 35 00:02:12,040 --> 00:02:15,240 Speaker 2: we're innately interested in. I'm not sure why why, but 36 00:02:15,320 --> 00:02:19,079 Speaker 2: it's like we're always attracted and repelled at the same 37 00:02:19,120 --> 00:02:21,680 Speaker 2: time by these things, and those are the things that 38 00:02:21,720 --> 00:02:24,320 Speaker 2: fascinate me. I'm kind of curious as to why people 39 00:02:24,320 --> 00:02:27,560 Speaker 2: are so interested in the yanky stuff, but we are. Yeah, 40 00:02:27,919 --> 00:02:29,480 Speaker 2: It's it's really cool. 41 00:02:30,639 --> 00:02:33,560 Speaker 1: It is really interesting because it makes some sense that 42 00:02:33,600 --> 00:02:38,160 Speaker 1: we are repelled by poop, because I mean, in some ways, 43 00:02:38,200 --> 00:02:42,480 Speaker 1: it's very practical, right, poop can spread parasites, can spread disease. 44 00:02:43,520 --> 00:02:46,480 Speaker 1: But it's so it's good that we're not, you know, 45 00:02:46,840 --> 00:02:49,079 Speaker 1: that we grow out of the phase of playing in 46 00:02:49,160 --> 00:02:53,280 Speaker 1: our own poop. However, it is still really interesting. I 47 00:02:53,280 --> 00:02:56,320 Speaker 1: think that we are drawn to kind of like you know, 48 00:02:56,520 --> 00:02:58,480 Speaker 1: you when you're on a hike and you see some 49 00:02:58,720 --> 00:03:01,600 Speaker 1: animal dung and you see there's stuff poking out of it. 50 00:03:02,120 --> 00:03:06,400 Speaker 1: I think people would be lying if, like they wouldn't 51 00:03:06,440 --> 00:03:09,200 Speaker 1: admit that that's a little interesting, and you're kind of like, okay, 52 00:03:09,200 --> 00:03:10,880 Speaker 1: I do kind of want to poke that with a 53 00:03:10,919 --> 00:03:14,440 Speaker 1: stick and find out what's going on in there. It's 54 00:03:15,240 --> 00:03:20,560 Speaker 1: both gross for good reason, but it's also really interesting exactly. 55 00:03:20,880 --> 00:03:22,799 Speaker 2: That's actually what led me to write a whole book 56 00:03:22,840 --> 00:03:24,679 Speaker 2: about poop, a different book. 57 00:03:24,680 --> 00:03:26,880 Speaker 1: You know, it was a different book, yes, but it 58 00:03:26,960 --> 00:03:27,280 Speaker 1: was like. 59 00:03:28,720 --> 00:03:31,720 Speaker 2: The surprising site, right that we when we look at 60 00:03:31,720 --> 00:03:34,200 Speaker 2: this stuff that's so gross, what we can actually learn 61 00:03:34,240 --> 00:03:37,880 Speaker 2: about the world, whether it's animals, you know, or the 62 00:03:37,920 --> 00:03:40,400 Speaker 2: rest of the world. All of the kind of big 63 00:03:40,480 --> 00:03:42,760 Speaker 2: questions that come out of scat. 64 00:03:43,440 --> 00:03:47,520 Speaker 1: Yeah, no, absolutely, I mean it's it's a whole thing 65 00:03:47,640 --> 00:03:51,760 Speaker 1: like in in research, it's so such an important actual 66 00:03:51,840 --> 00:03:56,680 Speaker 1: kind of like research method is collecting and studying animal poop, 67 00:03:57,320 --> 00:04:00,320 Speaker 1: which sounds you know, it sounds like not a fun job, 68 00:04:00,360 --> 00:04:02,480 Speaker 1: but then when you think about it, like that is 69 00:04:02,560 --> 00:04:04,480 Speaker 1: kind of cool because you get to be out in nature, 70 00:04:04,640 --> 00:04:07,160 Speaker 1: you collect a bunch of dung, and then you bring 71 00:04:07,240 --> 00:04:10,960 Speaker 1: it back for analysis. But there is so there is 72 00:04:11,040 --> 00:04:14,480 Speaker 1: one poop story I want uh to talk about a 73 00:04:14,520 --> 00:04:17,760 Speaker 1: little bit. It's in your book. Uh. It's I think 74 00:04:17,880 --> 00:04:21,360 Speaker 1: one of the most endearingly gross stories about poop. 75 00:04:21,520 --> 00:04:21,640 Speaker 2: Uh. 76 00:04:21,880 --> 00:04:26,400 Speaker 1: It is about puppy poop and the mother's response to 77 00:04:26,680 --> 00:04:32,000 Speaker 1: puppy poop. And it's it's really cute but also horrifyingly disgusting, 78 00:04:32,040 --> 00:04:34,479 Speaker 1: and I don't it's one of those things where it's 79 00:04:34,480 --> 00:04:39,799 Speaker 1: like perfectly combining cuteness with grossness exactly right. 80 00:04:40,200 --> 00:04:42,360 Speaker 2: So, if you're a mom and you've got a whole 81 00:04:42,480 --> 00:04:46,760 Speaker 2: litter of puppies and a you know together, what are 82 00:04:46,800 --> 00:04:49,680 Speaker 2: they going to do? A lot of is boop? Right, 83 00:04:49,960 --> 00:04:52,400 Speaker 2: and that's awesome, You're got to get rid of the stuff. 84 00:04:52,400 --> 00:04:56,040 Speaker 2: Plus what if there's parasites in it, which they're likely 85 00:04:56,240 --> 00:04:59,000 Speaker 2: are you know, if you're if you're not a pet 86 00:04:59,040 --> 00:05:01,760 Speaker 2: and taken care of, and so how do you deal 87 00:05:01,800 --> 00:05:05,120 Speaker 2: with that, because the puppy's immune system can't deal with 88 00:05:05,160 --> 00:05:10,360 Speaker 2: it at all. So mom sacrifices and she laps it up. 89 00:05:10,760 --> 00:05:14,520 Speaker 2: She carries it away from her babies through her own 90 00:05:14,560 --> 00:05:18,840 Speaker 2: digestive system, which is atrocious but not really because her 91 00:05:18,839 --> 00:05:22,800 Speaker 2: immune systems better handle these kinds of parasites. Plus she 92 00:05:23,240 --> 00:05:25,159 Speaker 2: basically hauls away and she can't pick it up with 93 00:05:25,200 --> 00:05:28,200 Speaker 2: her hands, right, so she basically hauls away through her 94 00:05:28,240 --> 00:05:32,160 Speaker 2: system and deposits it elsewhere. And if she deposits it elsewhere, 95 00:05:32,520 --> 00:05:36,159 Speaker 2: soon enough, the eggs haven't hatched for say, the round one, 96 00:05:36,760 --> 00:05:39,400 Speaker 2: and so she gets rid of them. It's just like 97 00:05:40,040 --> 00:05:42,520 Speaker 2: that in and of itself, that kind of behavioral adaptation 98 00:05:42,800 --> 00:05:46,560 Speaker 2: is phenomenal to me, Like how that came about. It's 99 00:05:46,600 --> 00:05:49,560 Speaker 2: just amazing gross but awesome too. 100 00:05:49,640 --> 00:05:52,600 Speaker 1: You know, it's so gross, but it's so sweet because 101 00:05:52,640 --> 00:05:56,920 Speaker 1: like obviously you know, it's this dog wanting to I mean, 102 00:05:57,560 --> 00:05:59,520 Speaker 1: it's hard to talk about animals in terms of what 103 00:05:59,560 --> 00:06:03,160 Speaker 1: they want, like because they have these instincts, right, and 104 00:06:03,480 --> 00:06:06,440 Speaker 1: this mother dog doesn't know why she's drawn to eating 105 00:06:06,480 --> 00:06:10,560 Speaker 1: her offsprings poop, but it is it is a It's 106 00:06:10,600 --> 00:06:14,479 Speaker 1: still sweet because it's like this this instinct to protect 107 00:06:14,520 --> 00:06:18,800 Speaker 1: your offspring to help them grow and develop. I mean, 108 00:06:18,960 --> 00:06:22,640 Speaker 1: it makes sense, that's how evolution works. But it's also 109 00:06:22,800 --> 00:06:26,159 Speaker 1: like it's one of the things that like, oh yeah, 110 00:06:26,200 --> 00:06:29,160 Speaker 1: like humans are not the only ones that deal with 111 00:06:29,279 --> 00:06:32,800 Speaker 1: baby poop, like other animals deal with baby poop. A 112 00:06:32,920 --> 00:06:36,599 Speaker 1: cute thing. I think Another kind of cute gross poop 113 00:06:36,600 --> 00:06:40,720 Speaker 1: thing is that birds, a lot of bird species, they 114 00:06:40,760 --> 00:06:44,440 Speaker 1: don't want to just have their baby birds poop and 115 00:06:44,640 --> 00:06:48,039 Speaker 1: have the poop accumulate and the nests. So the baby 116 00:06:48,120 --> 00:06:50,720 Speaker 1: bird poop is actually kind of comes in it. When 117 00:06:50,720 --> 00:06:52,839 Speaker 1: it comes out, it's sort of encased in this like 118 00:06:52,920 --> 00:06:57,080 Speaker 1: mucosal sack, and then it lifts its little butt up 119 00:06:57,680 --> 00:07:01,640 Speaker 1: and presents this poop too. It's and the mom bird 120 00:07:01,760 --> 00:07:03,520 Speaker 1: just like picks it up with her beak because you know, 121 00:07:03,560 --> 00:07:06,400 Speaker 1: she doesn't have hands, and carries it outside the nest 122 00:07:06,480 --> 00:07:09,640 Speaker 1: and deposits it outside the nest. So it's it's kind 123 00:07:09,680 --> 00:07:12,360 Speaker 1: of gross but also really cute. And I have seen 124 00:07:12,440 --> 00:07:15,160 Speaker 1: a video of someone who's taking care of a baby 125 00:07:15,160 --> 00:07:20,440 Speaker 1: bird that was sadly abandoned, and this person has to 126 00:07:21,080 --> 00:07:24,560 Speaker 1: take a pair of chompsticks and pick up the little 127 00:07:24,600 --> 00:07:27,640 Speaker 1: poop package. Every time this bird feeds and then like 128 00:07:27,680 --> 00:07:30,480 Speaker 1: presents its butt, presents this poop. It's really cute and 129 00:07:30,840 --> 00:07:33,160 Speaker 1: also obviously a little gross. 130 00:07:33,320 --> 00:07:37,679 Speaker 2: Isn't it phenomenal that that works that way. I actually 131 00:07:37,800 --> 00:07:40,960 Speaker 2: challenge kids and adults sometimes because we're all just being kids, 132 00:07:41,200 --> 00:07:46,000 Speaker 2: to watch a nest with binoculars and you can actually 133 00:07:46,080 --> 00:07:51,440 Speaker 2: tell when the young have hatched and started to digest 134 00:07:51,520 --> 00:07:54,960 Speaker 2: food or consume food because you'll start to see the 135 00:07:55,000 --> 00:07:59,360 Speaker 2: mother and add too, carrying away the fecals. It's just crazy. 136 00:08:00,080 --> 00:08:03,120 Speaker 1: So it's it's like, oh, yeah, other animals, I guess 137 00:08:03,200 --> 00:08:05,760 Speaker 1: have to deal with quote unquote poopy diapers, except it's 138 00:08:05,760 --> 00:08:07,200 Speaker 1: like a natural diaper. 139 00:08:07,800 --> 00:08:09,640 Speaker 2: Yeah, and it would be great if you know, we 140 00:08:09,720 --> 00:08:14,000 Speaker 2: had national diapers for our young as well, but yeah, 141 00:08:14,080 --> 00:08:14,679 Speaker 2: but we don't. 142 00:08:15,160 --> 00:08:20,520 Speaker 1: No, we don't, we don't. So another major theme in 143 00:08:20,560 --> 00:08:23,559 Speaker 1: your book is the immune system, which I mean, again, 144 00:08:23,640 --> 00:08:26,239 Speaker 1: I as an adult, got to kick out of reading 145 00:08:26,240 --> 00:08:28,080 Speaker 1: this book, but it is It is a great book 146 00:08:28,120 --> 00:08:29,840 Speaker 1: for kids as well, and I think this is a 147 00:08:29,880 --> 00:08:33,680 Speaker 1: great introduction to the immune system to kids because it's 148 00:08:34,160 --> 00:08:38,200 Speaker 1: it seems overwhelming, right, like the immune system, it's so complicated, 149 00:08:38,240 --> 00:08:40,520 Speaker 1: there's so many things. But I think it's also like 150 00:08:41,200 --> 00:08:44,560 Speaker 1: when you think about the parts of the immune system, 151 00:08:44,600 --> 00:08:48,360 Speaker 1: it gets a little bit easier to understand what's going 152 00:08:48,360 --> 00:08:51,200 Speaker 1: on because there's actually two major parts of the immune system, 153 00:08:51,200 --> 00:08:55,199 Speaker 1: and one is the innate or non specific immune system 154 00:08:56,040 --> 00:08:58,800 Speaker 1: and the adaptive immune system. And the innate immune system 155 00:08:59,240 --> 00:09:01,440 Speaker 1: we see every day when you look in the mirror, 156 00:09:01,520 --> 00:09:05,240 Speaker 1: you look at other people. It's our skin, it's our mucus, 157 00:09:05,320 --> 00:09:08,960 Speaker 1: it's our earwax, our hair, all of these things that 158 00:09:09,040 --> 00:09:14,680 Speaker 1: are a barrier to pathogens. There's also on the cellular 159 00:09:14,800 --> 00:09:19,880 Speaker 1: level innate immune cells, such as phagocytes that will actually 160 00:09:20,880 --> 00:09:24,560 Speaker 1: basically eat pathogens, eat things that are not supposed to 161 00:09:24,600 --> 00:09:28,400 Speaker 1: be there, break them down so that they are harmless. 162 00:09:28,440 --> 00:09:31,679 Speaker 1: Sometimes they break it down and then that's when the 163 00:09:32,480 --> 00:09:35,319 Speaker 1: adaptive immune system can come into play. So the adaptive 164 00:09:35,360 --> 00:09:38,200 Speaker 1: immune system is the part of the immune system that 165 00:09:38,240 --> 00:09:43,640 Speaker 1: actually launches a response specifically towards a type of pathogen 166 00:09:43,679 --> 00:09:47,920 Speaker 1: that it recognizes. So when you learn about a virus, 167 00:09:47,920 --> 00:09:50,600 Speaker 1: like you get infected with a virus, your body learns 168 00:09:50,640 --> 00:09:54,600 Speaker 1: about it, then it launches an adaptive immune response, and 169 00:09:54,640 --> 00:09:58,800 Speaker 1: this one is a little more precise and it can 170 00:09:58,840 --> 00:10:04,800 Speaker 1: be stronger. It can in a stronger reaction. But it's 171 00:10:04,960 --> 00:10:09,040 Speaker 1: really interesting because this adaptive immune system is in this 172 00:10:09,160 --> 00:10:13,719 Speaker 1: kind of like ballet with viruses and bacteria, this evolutionary 173 00:10:13,800 --> 00:10:18,239 Speaker 1: kind of arms race, and so both humans and animals 174 00:10:18,320 --> 00:10:24,280 Speaker 1: have adaptive and innate immune systems, and the balances can 175 00:10:24,320 --> 00:10:28,080 Speaker 1: be different. Some animals actually have a very weak adaptive 176 00:10:28,080 --> 00:10:32,160 Speaker 1: immune system or a very weak innate immune system, and 177 00:10:32,200 --> 00:10:34,480 Speaker 1: it kind of they balance each other out. Like the 178 00:10:35,640 --> 00:10:39,720 Speaker 1: deep sea anglerfish has actually kind of done away with 179 00:10:39,800 --> 00:10:43,960 Speaker 1: a lot of its adaptive immune system because the male 180 00:10:44,200 --> 00:10:48,120 Speaker 1: deep sea anglerfish attaches itself to the female and actually 181 00:10:48,240 --> 00:10:51,320 Speaker 1: kind of like fuses grafts itself onto the female. And 182 00:10:51,400 --> 00:10:56,480 Speaker 1: if this adaptive immune system knew that this male was there, 183 00:10:56,960 --> 00:10:59,079 Speaker 1: it would try to kill it, and that would put 184 00:10:59,120 --> 00:11:02,120 Speaker 1: a kibosh on the who whole like mating strategy of 185 00:11:02,160 --> 00:11:05,120 Speaker 1: these these fish. And so instead it's thought that it 186 00:11:05,160 --> 00:11:10,080 Speaker 1: overcomes this weaker adaptive immune system with a stronger passive 187 00:11:10,080 --> 00:11:14,079 Speaker 1: immune system, like a you know, thicker skin, more mucosal 188 00:11:14,400 --> 00:11:16,760 Speaker 1: membranes and so, and also just the fact that they're 189 00:11:16,800 --> 00:11:19,920 Speaker 1: not really running into each other a lot down there. 190 00:11:20,120 --> 00:11:24,880 Speaker 1: So sparsely populated, but in general animals have both an 191 00:11:24,920 --> 00:11:28,440 Speaker 1: innate and an adaptive immune system, and the innate immune 192 00:11:28,440 --> 00:11:32,960 Speaker 1: system can be really really interesting. Uh. And I really 193 00:11:33,000 --> 00:11:37,480 Speaker 1: love your examples in this book, especially when when we're 194 00:11:37,480 --> 00:11:41,120 Speaker 1: talking about slime. So what is so many animals are 195 00:11:41,160 --> 00:11:45,959 Speaker 1: slimy and it seems gross, but it's actually really interesting 196 00:11:46,040 --> 00:11:48,720 Speaker 1: and really important. So what is I mean, what is slime? 197 00:11:48,800 --> 00:11:51,160 Speaker 1: What is mucus? And what is what is it used for? 198 00:11:51,240 --> 00:11:53,640 Speaker 1: And why is it so popular in nature? 199 00:11:54,160 --> 00:11:56,840 Speaker 2: Oh, slime is awesome. Don't we love it? I mean, 200 00:11:56,960 --> 00:11:59,040 Speaker 2: it is just great. We all have it. It's there, 201 00:11:59,440 --> 00:12:01,280 Speaker 2: it's a part of of well I don't know an 202 00:12:01,320 --> 00:12:04,120 Speaker 2: animal that it's not a part of. But the amazing 203 00:12:04,200 --> 00:12:08,600 Speaker 2: thing is that slime protects us, you know, it's in 204 00:12:08,640 --> 00:12:11,880 Speaker 2: our nose and it's one of those other than the skin, 205 00:12:12,000 --> 00:12:14,200 Speaker 2: which is kind of the first barrier, right, But that 206 00:12:14,400 --> 00:12:18,160 Speaker 2: slime is there to catch intruders as they come into 207 00:12:18,240 --> 00:12:22,320 Speaker 2: the body and attack it. One of the stories I 208 00:12:22,360 --> 00:12:24,000 Speaker 2: love is about the hagfish, which. 209 00:12:23,840 --> 00:12:26,000 Speaker 1: People probably I love the hagfish. 210 00:12:26,080 --> 00:12:29,600 Speaker 2: They're so gross and so slimy, right, and their slime 211 00:12:29,679 --> 00:12:33,080 Speaker 2: does a number of different things, But it also includes 212 00:12:33,520 --> 00:12:39,480 Speaker 2: licensimes and that when they the license homes are just 213 00:12:39,520 --> 00:12:43,120 Speaker 2: these amazing attackers, right, So any bacteria or things like that, 214 00:12:43,160 --> 00:12:44,839 Speaker 2: they just go at it, hack it, wack it, and 215 00:12:44,920 --> 00:12:47,960 Speaker 2: smack it. And I just think that's pretty awesome to 216 00:12:48,040 --> 00:12:51,840 Speaker 2: look at kind of across the Indu Kingdom, how similar 217 00:12:52,400 --> 00:12:58,360 Speaker 2: adaptations are used, and also how every species has its 218 00:12:58,400 --> 00:13:04,599 Speaker 2: own unique way of attacking these invaders. One of the 219 00:13:04,640 --> 00:13:07,400 Speaker 2: stories I love to talk about is the ants, because 220 00:13:07,440 --> 00:13:09,439 Speaker 2: ants don't give a lot get a lot of credit, right, 221 00:13:09,720 --> 00:13:13,880 Speaker 2: I mean, there's little things, but amazingly scientists are studying 222 00:13:14,080 --> 00:13:18,960 Speaker 2: ants in order to better understand our immune system. One 223 00:13:18,960 --> 00:13:21,400 Speaker 2: of the things that happens, at least to my mind, 224 00:13:21,440 --> 00:13:24,920 Speaker 2: when I'm understanding immune systems is it's so complex it's 225 00:13:24,960 --> 00:13:28,600 Speaker 2: hard to hard to visualize, right, But when you think 226 00:13:28,640 --> 00:13:33,480 Speaker 2: about an ant colony as an individual a super organism, 227 00:13:34,280 --> 00:13:38,160 Speaker 2: you can kind of get a better sense of how 228 00:13:38,240 --> 00:13:42,120 Speaker 2: a human body might work. For example, we've all seen yeah, yeah, right, 229 00:13:42,200 --> 00:13:44,200 Speaker 2: Like we've all seen an ant hill. We see ants 230 00:13:44,240 --> 00:13:47,640 Speaker 2: go in, right, and if you think about that ant hill, 231 00:13:47,840 --> 00:13:51,760 Speaker 2: if you touch it, you know how they react. So 232 00:13:52,080 --> 00:13:54,880 Speaker 2: thinking that that ant hill is kind of like our skin, 233 00:13:55,600 --> 00:14:00,440 Speaker 2: the outside surface, Like if we attack it, they're gonna 234 00:14:00,440 --> 00:14:03,679 Speaker 2: attack us, just like if something breaks our skin barrier, 235 00:14:04,280 --> 00:14:06,520 Speaker 2: our immune system's gonna attack it. But then there are 236 00:14:06,559 --> 00:14:08,840 Speaker 2: the normal places where things go into the ant hill, 237 00:14:09,000 --> 00:14:11,920 Speaker 2: like the openings, you know, the entrance ways. But right 238 00:14:11,920 --> 00:14:15,840 Speaker 2: there the entrance ways to that ant hill are guards, 239 00:14:15,880 --> 00:14:18,280 Speaker 2: and those guards are gonna attack anything that tries to 240 00:14:18,280 --> 00:14:21,160 Speaker 2: come in that is not the self, right, just like 241 00:14:21,200 --> 00:14:23,720 Speaker 2: our nose that slim in our nose, it's gonna do 242 00:14:23,760 --> 00:14:26,720 Speaker 2: the same thing, right, And as you go deeper into 243 00:14:26,720 --> 00:14:29,080 Speaker 2: the ant hill, you have more and more protection. What 244 00:14:29,200 --> 00:14:32,320 Speaker 2: was amazing to me is as I researched for this book, 245 00:14:32,360 --> 00:14:34,880 Speaker 2: I discovered I never thought about the fact that ants 246 00:14:34,920 --> 00:14:38,000 Speaker 2: are exposed to fungus all the time because they live 247 00:14:38,000 --> 00:14:39,920 Speaker 2: in the soil, and fungus lives in the soil, and 248 00:14:40,120 --> 00:14:43,040 Speaker 2: fungus would just love to like dive into an ant 249 00:14:43,080 --> 00:14:48,280 Speaker 2: hill and create an epidemic because one little ant carrying 250 00:14:48,320 --> 00:14:52,400 Speaker 2: fungus spores into the ant hill. Oh, they could go crazy. 251 00:14:52,760 --> 00:14:55,120 Speaker 2: But you know, you've got those guards on the doorway 252 00:14:55,400 --> 00:14:58,360 Speaker 2: that are gonna maybe catch those spores. But as the 253 00:14:58,400 --> 00:15:00,920 Speaker 2: ant worker ant goes deeper or into the ant hill, 254 00:15:01,920 --> 00:15:06,360 Speaker 2: there's there are other cleaner ants sanitation ants, right, And 255 00:15:06,440 --> 00:15:10,640 Speaker 2: so what's fascinating to be is that these ants, these 256 00:15:10,640 --> 00:15:15,320 Speaker 2: sanitation ants, remove these fungal spores, but yet don't get 257 00:15:15,360 --> 00:15:18,280 Speaker 2: sick themselves. And I was like how, And so I 258 00:15:18,320 --> 00:15:21,480 Speaker 2: looked into the research and it's just amazing. This guy, 259 00:15:21,560 --> 00:15:25,120 Speaker 2: Christopher Poull is doing some awesome research with them. One 260 00:15:25,160 --> 00:15:27,400 Speaker 2: of the things that happens in certain ants is they 261 00:15:27,880 --> 00:15:31,520 Speaker 2: they actually put the spores in their mouths. Wait, leaning 262 00:15:31,680 --> 00:15:33,560 Speaker 2: the ants they're putting the spores in their mouth It 263 00:15:33,960 --> 00:15:35,480 Speaker 2: sounds really really like the. 264 00:15:35,440 --> 00:15:36,760 Speaker 1: Wrong thing to get dangerous. 265 00:15:36,880 --> 00:15:39,480 Speaker 2: Yeah, right, but they have these pockets in their mouth, 266 00:15:39,800 --> 00:15:42,520 Speaker 2: little pockets in their mouths that they stuff the spores 267 00:15:42,560 --> 00:15:45,240 Speaker 2: into and then they carry the spores off into the 268 00:15:45,280 --> 00:15:47,120 Speaker 2: garbage basically and get. 269 00:15:47,040 --> 00:15:50,000 Speaker 1: Rid of them and spit it out. Yeah, that's amazing. 270 00:15:50,200 --> 00:15:53,400 Speaker 2: And this story goes deeper and deeper because in this story, 271 00:15:53,520 --> 00:15:58,360 Speaker 2: actually if the young, the pupa, the larvae are infected 272 00:15:58,680 --> 00:16:05,280 Speaker 2: by spores, the sanitation ants actually destroy them, which sounds. 273 00:16:05,040 --> 00:16:08,080 Speaker 1: Terrible, right, it's zombie apocalypse rules, you know. 274 00:16:08,920 --> 00:16:12,840 Speaker 2: The zombie absolu And but it's such an analogy to 275 00:16:12,960 --> 00:16:15,600 Speaker 2: our own bodies, where if we have cells that are 276 00:16:15,600 --> 00:16:19,040 Speaker 2: infected guess what they have to die? 277 00:16:19,320 --> 00:16:25,080 Speaker 1: Apoptosis is. It's it's really interesting because the cell death 278 00:16:25,520 --> 00:16:29,080 Speaker 1: sounds really bad. Oh, cell death, it's the thing that 279 00:16:29,200 --> 00:16:33,800 Speaker 1: keeps us alive. We need our cells to die. They 280 00:16:33,880 --> 00:16:37,720 Speaker 1: can replenish. Obviously. If you have too much cellular death, 281 00:16:37,800 --> 00:16:41,040 Speaker 1: that's a bad thing. But if you have no cellular death, 282 00:16:41,080 --> 00:16:44,680 Speaker 1: that's actually what cancer basically is. It's when your cell 283 00:16:45,200 --> 00:16:48,800 Speaker 1: doesn't know how to die. It's your cell loses the ability. 284 00:16:48,800 --> 00:16:53,680 Speaker 1: There's a mutation that prevents it from uh from dying 285 00:16:54,320 --> 00:16:59,920 Speaker 1: from this process called apoptosis, and that is really really bad. 286 00:17:00,440 --> 00:17:04,959 Speaker 1: It's also what protects us from pathogens, because an infected 287 00:17:05,080 --> 00:17:09,199 Speaker 1: cell can be like, oh, this isn't good actually, like 288 00:17:09,440 --> 00:17:15,400 Speaker 1: destroy itself, and even through destroying itself, can can cause 289 00:17:15,600 --> 00:17:18,199 Speaker 1: the virus to break apart, and then that can be 290 00:17:18,240 --> 00:17:20,679 Speaker 1: picked up by other cells, which go, oh, this is 291 00:17:20,840 --> 00:17:24,040 Speaker 1: an interesting thing to learn from and bring those little 292 00:17:24,160 --> 00:17:27,800 Speaker 1: those little antigens, the parts of the virus that are 293 00:17:28,359 --> 00:17:31,080 Speaker 1: that can be learned from. And so yeah, it's really 294 00:17:31,200 --> 00:17:35,160 Speaker 1: interesting how like the the immune system does attack our 295 00:17:35,200 --> 00:17:39,919 Speaker 1: own bodies sometimes and that's both important in life saving 296 00:17:40,680 --> 00:17:43,800 Speaker 1: and can also cause a lot of problems, right like, 297 00:17:43,920 --> 00:17:48,080 Speaker 1: if if our immune system attacks our own cells too strongly, 298 00:17:48,520 --> 00:17:51,280 Speaker 1: that can actually kill us. And if they don't attack 299 00:17:51,560 --> 00:17:55,440 Speaker 1: cells strongly enough, it's too weak of an immune response, 300 00:17:55,640 --> 00:17:59,959 Speaker 1: and so then the virus can actually directly harm our 301 00:18:00,240 --> 00:18:04,640 Speaker 1: cells and go and be and replicate unabated. But yeah, 302 00:18:04,680 --> 00:18:09,320 Speaker 1: that bounds. I love the connection to the ants because 303 00:18:09,880 --> 00:18:14,399 Speaker 1: you see these kind of very complex colony behaviors. Is 304 00:18:14,560 --> 00:18:18,199 Speaker 1: very much like how the immune system works because with ants, 305 00:18:18,280 --> 00:18:22,240 Speaker 1: you have a hierarchy. It's use sociality, right, Like, so 306 00:18:22,280 --> 00:18:26,320 Speaker 1: you have very specific roles that each of the ants has, 307 00:18:26,760 --> 00:18:29,760 Speaker 1: and you have like obviously the queen ants, which are 308 00:18:29,760 --> 00:18:32,520 Speaker 1: the ones that are the only ones that can reproduce generally, 309 00:18:32,920 --> 00:18:36,320 Speaker 1: but you also have different roles for the ants and something. 310 00:18:36,600 --> 00:18:39,679 Speaker 1: It can also be a different role based on the 311 00:18:39,720 --> 00:18:42,240 Speaker 1: time and the ants life or the same thing with bees, 312 00:18:42,320 --> 00:18:46,000 Speaker 1: right like a bees life cycle, their role might change 313 00:18:46,080 --> 00:18:48,840 Speaker 1: as it gets older. And so you see a very 314 00:18:48,840 --> 00:18:51,640 Speaker 1: similar thing in the immune system where you have these 315 00:18:51,680 --> 00:18:56,080 Speaker 1: immune cells and they have these It's kind of like 316 00:18:56,119 --> 00:18:59,439 Speaker 1: a use social system within our own bodies. Because you 317 00:18:59,560 --> 00:19:04,119 Speaker 1: have this hierarchical system, you have these very specific roles 318 00:19:04,119 --> 00:19:07,000 Speaker 1: that each of the cells play and these rules they 319 00:19:07,040 --> 00:19:11,080 Speaker 1: have to play by, and it's really interesting because we 320 00:19:11,200 --> 00:19:14,800 Speaker 1: have to have to be a unified organism. There has 321 00:19:14,880 --> 00:19:20,760 Speaker 1: to be that sacrifice in order to help the larger system, right, 322 00:19:20,840 --> 00:19:24,280 Speaker 1: the entire ant colony or the entire human to function. 323 00:19:24,359 --> 00:19:27,199 Speaker 1: And without that kind of sacrifice of these cells, we 324 00:19:27,280 --> 00:19:31,760 Speaker 1: couldn't function as an entire organism, which I think is 325 00:19:31,800 --> 00:19:32,560 Speaker 1: so interesting. 326 00:19:33,240 --> 00:19:36,040 Speaker 2: Yeah. Right. And the fact, one of the other things 327 00:19:36,040 --> 00:19:38,760 Speaker 2: that I found interesting about the story of about the 328 00:19:38,840 --> 00:19:43,960 Speaker 2: ants is that the worker ants basically are inoculating themselves 329 00:19:44,280 --> 00:19:49,280 Speaker 2: against the disease. Those interesting. Yeah, So if they're exposed 330 00:19:49,760 --> 00:19:54,520 Speaker 2: to a small amount scores, which they do, as you know, 331 00:19:54,920 --> 00:19:59,880 Speaker 2: workers bring in spores from the environment than those workers 332 00:20:00,119 --> 00:20:04,359 Speaker 2: and then those immune sorry, those sanitary ants, sanitization ants 333 00:20:05,240 --> 00:20:06,280 Speaker 2: are immune. 334 00:20:06,000 --> 00:20:07,760 Speaker 1: They develop immunity. That's incredible. 335 00:20:08,200 --> 00:20:11,479 Speaker 2: Yeah. Again, it's just a great analogy because we can 336 00:20:11,560 --> 00:20:15,280 Speaker 2: visualize that ant moving here and there and everywhere, and 337 00:20:15,320 --> 00:20:19,760 Speaker 2: in fact, in our body and all animals, you know, 338 00:20:20,560 --> 00:20:25,360 Speaker 2: the cells are kind of like those little ant. Can 339 00:20:25,400 --> 00:20:28,560 Speaker 2: I go back to something you mentioned absolutely, and that 340 00:20:28,920 --> 00:20:33,679 Speaker 2: is you mentioned how our immune systems sometimes kind of 341 00:20:33,800 --> 00:20:38,440 Speaker 2: can react and overreact and how that affects our body, 342 00:20:38,880 --> 00:20:42,959 Speaker 2: you know, speaking specifically about viruses, because that's something that 343 00:20:43,000 --> 00:20:46,199 Speaker 2: we're all very interested in these days. Yeah, you know, 344 00:20:47,800 --> 00:20:51,720 Speaker 2: the symptoms really are just our body reacting and overreacting. 345 00:20:52,160 --> 00:20:54,440 Speaker 2: And that reminds me of the story of the bats, 346 00:20:54,760 --> 00:20:57,320 Speaker 2: which just blows my mind. 347 00:20:57,640 --> 00:21:01,040 Speaker 1: Mm hmm. I love bats, and I let there well, 348 00:21:01,240 --> 00:21:04,040 Speaker 1: I don't want to interrupt you, but I just they're 349 00:21:04,160 --> 00:21:07,320 Speaker 1: so interesting to me, and especially when it comes to immunity, 350 00:21:08,000 --> 00:21:11,680 Speaker 1: because they have such big requirements in terms of energy 351 00:21:11,760 --> 00:21:15,440 Speaker 1: for flying. A mammal that can fly, it's it's an 352 00:21:15,480 --> 00:21:20,199 Speaker 1: incredible feat. It's this warm blooded, thermal regulating animal that 353 00:21:20,240 --> 00:21:26,760 Speaker 1: can also fly, and it has a relatively short evolutionary 354 00:21:27,160 --> 00:21:30,960 Speaker 1: history of flight when you compare it to say, like insects, 355 00:21:31,359 --> 00:21:35,040 Speaker 1: and so it's really really interesting. And the pressures, the 356 00:21:36,119 --> 00:21:40,119 Speaker 1: metabolic and energy pressures on these bats are incredible, and 357 00:21:40,160 --> 00:21:43,600 Speaker 1: so they have really interesting immune systems. And anyways, now 358 00:21:43,640 --> 00:21:45,320 Speaker 1: I'm gonna let you you tell your story. 359 00:21:45,440 --> 00:21:48,119 Speaker 2: No, that's great. I love it because one of the 360 00:21:48,160 --> 00:21:52,080 Speaker 2: things about bats is there's still so many questions about them, right, 361 00:21:52,320 --> 00:21:55,080 Speaker 2: like this idea that they can fly, but yet to 362 00:21:55,280 --> 00:21:59,120 Speaker 2: do that requires this huge metabolic rate. How do they 363 00:21:59,160 --> 00:22:02,160 Speaker 2: survive that? Because if we tried to do that, our 364 00:22:02,160 --> 00:22:05,240 Speaker 2: body would crash in so many ways. Yeah, number one, 365 00:22:05,280 --> 00:22:08,399 Speaker 2: because we'd be producing so much waste that our immune 366 00:22:08,400 --> 00:22:12,040 Speaker 2: system would be going after that waste and and it 367 00:22:12,080 --> 00:22:13,959 Speaker 2: would just be it would be it would be a 368 00:22:14,119 --> 00:22:18,879 Speaker 2: storm of our immune system. Right. So scientists are really 369 00:22:18,960 --> 00:22:22,399 Speaker 2: curious about how bads actually survive. I mean most people 370 00:22:22,400 --> 00:22:25,320 Speaker 2: have heard that, you know, bats can carry many many 371 00:22:25,440 --> 00:22:31,359 Speaker 2: viruses and that we can't in fact acquire viruses from 372 00:22:31,400 --> 00:22:34,440 Speaker 2: bats and vice versa. But you know, how is that? 373 00:22:34,560 --> 00:22:37,240 Speaker 2: How can they survive? I mean, there's so many bad species, 374 00:22:37,280 --> 00:22:40,680 Speaker 2: there's bats across the entire world except for Antarctica, and 375 00:22:40,720 --> 00:22:45,000 Speaker 2: how can they be surviving so many viruses? And come 376 00:22:45,160 --> 00:22:48,280 Speaker 2: find out one of the one of the things is 377 00:22:48,400 --> 00:22:54,360 Speaker 2: their innate immune system is strong, so strong that that 378 00:22:54,440 --> 00:22:58,879 Speaker 2: may be driving the evolution of viruses, right because their bodies. 379 00:22:59,520 --> 00:23:03,640 Speaker 2: In order for a virus to successfully infect that, it's 380 00:23:03,640 --> 00:23:07,639 Speaker 2: got to be pretty amazing. The interesting story that I 381 00:23:07,680 --> 00:23:10,080 Speaker 2: discovered as I was doing research for this book is 382 00:23:10,119 --> 00:23:14,920 Speaker 2: that the innate While the innate immune system, the first 383 00:23:15,400 --> 00:23:20,080 Speaker 2: immune system basically is so strong, the secondary or the 384 00:23:20,320 --> 00:23:23,680 Speaker 2: adaptive required depending on who you're talking to, that immune 385 00:23:23,680 --> 00:23:27,119 Speaker 2: system basically says, guess what, virus, if you made it 386 00:23:27,160 --> 00:23:31,560 Speaker 2: past that first line? Okay, so what if the immune 387 00:23:31,600 --> 00:23:37,440 Speaker 2: system decides to not react? And I'm saying this anthropomorphically obviously, 388 00:23:37,600 --> 00:23:44,320 Speaker 2: but if the immune system isn't reacting in this storm, 389 00:23:44,640 --> 00:23:48,840 Speaker 2: the symptoms aren't there, right, And in order to figure 390 00:23:48,880 --> 00:23:53,360 Speaker 2: that out. The work that went into that was amazing 391 00:23:53,800 --> 00:23:56,560 Speaker 2: because you had to actually look at what was happening 392 00:23:56,600 --> 00:24:00,959 Speaker 2: on a cellular level to create that storm. This inflammation 393 00:24:01,040 --> 00:24:04,439 Speaker 2: they call it the inflammazone And basically what's happening is, 394 00:24:04,920 --> 00:24:10,159 Speaker 2: in comparison to other mammals, bats turned down like a dial, 395 00:24:10,600 --> 00:24:14,720 Speaker 2: they turn down or they dial down that inflammation rate. 396 00:24:15,520 --> 00:24:17,680 Speaker 2: And when you do that, you don't have the information. 397 00:24:17,720 --> 00:24:19,399 Speaker 2: When you don't have the information, therefore you don't have 398 00:24:19,440 --> 00:24:23,400 Speaker 2: the symptoms. Basically, they're kind of saying them, Oh, wait, 399 00:24:23,560 --> 00:24:26,280 Speaker 2: you're really hurting me, virus, Why don't I just let 400 00:24:26,320 --> 00:24:28,600 Speaker 2: you be? Like, we don't have to fight, which I 401 00:24:28,680 --> 00:24:31,320 Speaker 2: think is a really cool message just to think about. Right, 402 00:24:31,880 --> 00:24:34,720 Speaker 2: if you're not really killing me, Yeah, you know, we 403 00:24:34,800 --> 00:24:38,400 Speaker 2: can deal, we can survive. Yeah, we can coexist, which 404 00:24:38,440 --> 00:24:39,119 Speaker 2: is powerful. 405 00:24:40,200 --> 00:24:43,359 Speaker 1: Yeah, it's really interesting. I mean, you do talk about 406 00:24:43,400 --> 00:24:47,639 Speaker 1: this a bit in Sick, which again I love because 407 00:24:47,640 --> 00:24:50,920 Speaker 1: this is so cool to like introduce these concepts of 408 00:24:51,160 --> 00:24:54,719 Speaker 1: like the fact that we do have some viral DNA 409 00:24:55,040 --> 00:24:59,280 Speaker 1: still with us, right, Like viruses don't always viruses in 410 00:24:59,440 --> 00:25:04,040 Speaker 1: bacteria especially like are not always dangerous. They can actually 411 00:25:04,720 --> 00:25:08,639 Speaker 1: start to incorporate themselves that there's like a there can 412 00:25:08,680 --> 00:25:14,879 Speaker 1: be like a mutualistic symbiosis between animals and bacteria and 413 00:25:14,920 --> 00:25:19,800 Speaker 1: even viruses, And it's so cool. And I mean, the 414 00:25:20,119 --> 00:25:23,000 Speaker 1: other thing with bats is, like I think it's it's 415 00:25:23,040 --> 00:25:26,879 Speaker 1: a really important thing for people to understand that the 416 00:25:27,000 --> 00:25:30,520 Speaker 1: reason that bats can have these these viruses that can 417 00:25:30,520 --> 00:25:33,760 Speaker 1: be dangerous for humans is not because they're dirty. They're 418 00:25:33,760 --> 00:25:38,080 Speaker 1: actually very hygienic, uh, they but the fact that they 419 00:25:38,119 --> 00:25:41,840 Speaker 1: have these this very different kind of immune system, this 420 00:25:41,960 --> 00:25:45,879 Speaker 1: immune system that has adapted differently from urts. So like 421 00:25:45,960 --> 00:25:48,199 Speaker 1: if they when they encounter a virus, right and they 422 00:25:48,200 --> 00:25:53,240 Speaker 1: don't have they have successfully whittled down the viral load 423 00:25:53,359 --> 00:25:58,399 Speaker 1: because of their incredible innate immune system, and then they 424 00:25:58,400 --> 00:26:01,440 Speaker 1: don't have as strong of an inflammatory response, so then 425 00:26:01,440 --> 00:26:05,680 Speaker 1: they survive. When we're introduced to that same virus, our 426 00:26:05,680 --> 00:26:09,679 Speaker 1: innate response, our adaptive response is going to be much stronger, 427 00:26:10,240 --> 00:26:13,960 Speaker 1: and so we can actually even though without our adaptive 428 00:26:13,960 --> 00:26:16,480 Speaker 1: immune system we wouldn't get very far because we wouldn't 429 00:26:16,480 --> 00:26:20,760 Speaker 1: be able to destroy viruses and pathogens that could replicate 430 00:26:20,800 --> 00:26:24,960 Speaker 1: inside of us. It also means that we can have 431 00:26:25,040 --> 00:26:30,080 Speaker 1: this massive inflammatory response, a cytokine storm, which is essentially 432 00:26:30,560 --> 00:26:33,520 Speaker 1: like a game of dominoes gone wrong inside of your 433 00:26:33,560 --> 00:26:39,120 Speaker 1: immune system, and it can be really damaging. So it's 434 00:26:39,160 --> 00:26:43,080 Speaker 1: like the same immune response that can save your life, right, 435 00:26:43,160 --> 00:26:46,639 Speaker 1: like a fever which is killing off a bacteria or 436 00:26:47,640 --> 00:26:50,800 Speaker 1: virus which can save your life, can also kill you. 437 00:26:50,880 --> 00:26:56,879 Speaker 1: But back to the concept of these viruses not always 438 00:26:57,520 --> 00:27:00,679 Speaker 1: being bad for us, Like the the fact that we 439 00:27:00,880 --> 00:27:04,560 Speaker 1: have like in our DNA now like from you know, 440 00:27:04,840 --> 00:27:08,240 Speaker 1: millions of years ago, like viral DNA that has inserted 441 00:27:08,240 --> 00:27:11,080 Speaker 1: itself into our DNA and then it just works out 442 00:27:11,320 --> 00:27:12,720 Speaker 1: is incredible to me. 443 00:27:13,400 --> 00:27:15,280 Speaker 2: Yeah, we think of that, you know, we have this 444 00:27:15,400 --> 00:27:18,360 Speaker 2: bias that viruses are bad. Well, guess what, So much 445 00:27:18,400 --> 00:27:23,160 Speaker 2: of our DNA is viral, which I had no idea 446 00:27:23,320 --> 00:27:27,280 Speaker 2: how that happened, right, I didn't understand the entire concept 447 00:27:27,320 --> 00:27:32,600 Speaker 2: of retroviruses, which okay, can we we can dive deeply 448 00:27:32,640 --> 00:27:34,440 Speaker 2: into this I didn't get to let's do it. There's 449 00:27:34,440 --> 00:27:36,840 Speaker 2: an entire chapter that didn't make it into this book 450 00:27:37,680 --> 00:27:41,240 Speaker 2: because it was so complex, but it just am so 451 00:27:41,520 --> 00:27:47,120 Speaker 2: fascinated by it. Right, So, retroviruses, all viruses, we most 452 00:27:47,160 --> 00:27:49,399 Speaker 2: of us know that the virus has to enter the 453 00:27:49,680 --> 00:27:54,240 Speaker 2: cell of the host to be replicated, right, but retroviruses 454 00:27:54,280 --> 00:27:57,840 Speaker 2: go deeper than that. So once they enter the cell 455 00:27:59,320 --> 00:28:02,720 Speaker 2: and their DNA is their their genetic material I should say, 456 00:28:03,520 --> 00:28:10,000 Speaker 2: is replicated, then that genetic material actually enters the cell's nucleus, 457 00:28:10,680 --> 00:28:13,480 Speaker 2: which is like whoa who, Well, like that's the safe house, 458 00:28:13,560 --> 00:28:15,680 Speaker 2: you know, like the cell is one thing. But entering 459 00:28:15,720 --> 00:28:19,040 Speaker 2: the nucleus, where like are the genetic material of the 460 00:28:19,119 --> 00:28:24,399 Speaker 2: host exists, You're like entering the vault. And then they 461 00:28:25,680 --> 00:28:33,560 Speaker 2: that retroviral genetic material inserts itself into the host's genetic material, 462 00:28:33,640 --> 00:28:37,679 Speaker 2: which is like so mind blowing that that can actually happen. 463 00:28:38,000 --> 00:28:40,440 Speaker 2: But if you think about it again, it's this concept 464 00:28:40,560 --> 00:28:44,880 Speaker 2: that like, do we have to be a war? We're 465 00:28:44,920 --> 00:28:47,760 Speaker 2: two there are two organisms here, and you can either 466 00:28:47,840 --> 00:28:49,520 Speaker 2: be a war and one can win and the other 467 00:28:49,600 --> 00:28:53,600 Speaker 2: can lose or you could coexist. And an amazing way 468 00:28:53,720 --> 00:29:00,120 Speaker 2: that's happened. And every placental mammal, every placental mammal, so 469 00:29:00,280 --> 00:29:03,440 Speaker 2: we think of that as you know us and other 470 00:29:05,000 --> 00:29:11,600 Speaker 2: large organizers, but we all have retroviral DNA in us 471 00:29:12,000 --> 00:29:15,200 Speaker 2: that allows us to give live birth. 472 00:29:16,360 --> 00:29:17,640 Speaker 1: It's amazing, amazed. 473 00:29:17,680 --> 00:29:20,160 Speaker 2: Okay, I have to tell this story about these kittens 474 00:29:20,160 --> 00:29:22,520 Speaker 2: that came into my life as I was doing this research. 475 00:29:24,040 --> 00:29:25,800 Speaker 2: There was a cat that got hit by a car 476 00:29:25,880 --> 00:29:30,320 Speaker 2: and long story short, she was pregnant and she was 477 00:29:30,440 --> 00:29:35,160 Speaker 2: not gonna make it, but she was doing well enough 478 00:29:35,720 --> 00:29:38,440 Speaker 2: that she crawled up in my lap and gave birth 479 00:29:38,480 --> 00:29:43,680 Speaker 2: to kittens. Wow, they were amazing. Well, I had never 480 00:29:43,960 --> 00:29:48,280 Speaker 2: observed that, and I had been doing this research about placenta, 481 00:29:48,320 --> 00:29:50,800 Speaker 2: so I got very interested in the placenta and how 482 00:29:50,840 --> 00:29:56,400 Speaker 2: this happened. Turns out, you know, and a zygod an 483 00:29:56,440 --> 00:30:00,960 Speaker 2: embryo is is going to be considered non self right right, Yes, 484 00:30:01,680 --> 00:30:07,840 Speaker 2: an outside invader inside the mother. The question comes now 485 00:30:07,920 --> 00:30:12,840 Speaker 2: in the world does a mother's body accept this invader 486 00:30:12,960 --> 00:30:16,600 Speaker 2: in because they shouldn't. Like the immune system from the 487 00:30:16,600 --> 00:30:21,560 Speaker 2: mother should attack this invader and kick it out well, 488 00:30:21,960 --> 00:30:27,280 Speaker 2: who's really good at checking the immune system viruses. In 489 00:30:27,400 --> 00:30:30,520 Speaker 2: order for a virus to enter our cell, it has 490 00:30:30,560 --> 00:30:32,520 Speaker 2: to chrick us. It has to have that message on 491 00:30:32,600 --> 00:30:35,040 Speaker 2: its surface, that protein that says, wait, wait, I'm part 492 00:30:35,080 --> 00:30:37,600 Speaker 2: of you. It's okay, don't worry about me. I'm just 493 00:30:38,160 --> 00:30:38,760 Speaker 2: along here. 494 00:30:39,360 --> 00:30:42,600 Speaker 1: Fake the fake ID that sells carry around because we 495 00:30:42,680 --> 00:30:46,000 Speaker 1: have these, we have essentially tiny cops inside of our 496 00:30:46,040 --> 00:30:49,600 Speaker 1: bodies called natural kill our cells that will go around 497 00:30:49,680 --> 00:30:54,360 Speaker 1: checking everyone's passport, checking everyone's papers. It's a little bit 498 00:30:54,720 --> 00:30:57,880 Speaker 1: you know, it's a little authoritarian inside our bodies sometimes. 499 00:30:58,320 --> 00:31:02,000 Speaker 1: And so a lot of viruses have created this like 500 00:31:02,400 --> 00:31:05,960 Speaker 1: basically a fake ID to show the natural killerself like 501 00:31:06,000 --> 00:31:09,240 Speaker 1: I'm legit. But yeah, that that can be applied to 502 00:31:10,200 --> 00:31:12,800 Speaker 1: protecting our own offspring is amazing. 503 00:31:13,240 --> 00:31:17,040 Speaker 2: Right. So if that if that future offspring didn't have 504 00:31:18,240 --> 00:31:24,240 Speaker 2: that retroviral genetic material that therefore programmed the proteins on 505 00:31:24,320 --> 00:31:27,840 Speaker 2: its surface to tell the mother, hey it's okay, let 506 00:31:27,880 --> 00:31:31,800 Speaker 2: me in the placenta, would never happen, right, The attachment 507 00:31:32,080 --> 00:31:36,200 Speaker 2: would never happen. And so every single one of us 508 00:31:36,480 --> 00:31:40,000 Speaker 2: we should be thanking the viruses right because we were born. 509 00:31:40,880 --> 00:31:43,960 Speaker 2: It's just amazing and a phenomenal thing. Kind of on 510 00:31:44,000 --> 00:31:46,920 Speaker 2: a little another aside, but it's amazing. Is there's there 511 00:31:46,920 --> 00:31:49,560 Speaker 2: are some lizards that do this as well. Wait, lizards, 512 00:31:49,800 --> 00:31:53,520 Speaker 2: Lizards are not supposed to have licentius, but yet they 513 00:31:53,560 --> 00:31:57,800 Speaker 2: did some of them down right, It's because this retroviral 514 00:31:57,920 --> 00:32:02,680 Speaker 2: invasion has happened so many times across times. 515 00:32:03,200 --> 00:32:07,240 Speaker 1: Yeah, it's it's amazing. Yeah, it's so it's I mean, 516 00:32:07,280 --> 00:32:09,920 Speaker 1: it's the same. I think that people are more familiar 517 00:32:10,080 --> 00:32:12,520 Speaker 1: with this concept when it comes to bacteria, right, Like, 518 00:32:12,560 --> 00:32:16,960 Speaker 1: we've got good bacteria and bad bacteria. Uh, and a 519 00:32:17,000 --> 00:32:19,480 Speaker 1: lot of it is not even just good or bad bacteria, 520 00:32:19,520 --> 00:32:22,200 Speaker 1: but the balance of bacteria, right Like, it's a specific 521 00:32:22,240 --> 00:32:27,240 Speaker 1: balance of which bacteria you have and your own immune system. 522 00:32:27,320 --> 00:32:31,520 Speaker 1: Right for some people, bacteria that's generally good and fine 523 00:32:31,600 --> 00:32:33,880 Speaker 1: can be bad for someone else because their immune system 524 00:32:34,120 --> 00:32:36,880 Speaker 1: reacts too strongly to it. So there are all these 525 00:32:36,920 --> 00:32:40,080 Speaker 1: different factors that come into play. But that's the same 526 00:32:40,640 --> 00:32:43,720 Speaker 1: thing with like viruses, right like most I mean, it's 527 00:32:43,760 --> 00:32:47,000 Speaker 1: true that most times you catch some kind of virus, 528 00:32:47,120 --> 00:32:50,240 Speaker 1: right like a cold or a flu, it's not good 529 00:32:50,280 --> 00:32:53,520 Speaker 1: for you. It's not good necessarily good to get sick. 530 00:32:54,560 --> 00:32:57,920 Speaker 1: You know, sometimes it's it's just a fact of life 531 00:32:57,960 --> 00:33:00,320 Speaker 1: that you're going to get sick. Uh. And some times 532 00:33:00,360 --> 00:33:03,880 Speaker 1: the timing of when you get sick can be really important, 533 00:33:03,960 --> 00:33:07,560 Speaker 1: right Like, if you get certain viruses, you absolutely do 534 00:33:07,600 --> 00:33:10,040 Speaker 1: not want to get as an infant because your immune 535 00:33:10,040 --> 00:33:12,880 Speaker 1: system's too weak. But some if you do get as 536 00:33:12,880 --> 00:33:16,720 Speaker 1: an infant, they're less serious when you're an adult. Now 537 00:33:17,080 --> 00:33:21,680 Speaker 1: we have vaccines which make it a lot safer to 538 00:33:21,720 --> 00:33:26,880 Speaker 1: introduce viral information to infants and to adults without us 539 00:33:26,920 --> 00:33:30,160 Speaker 1: having to go through the risks of infection. But it's 540 00:33:30,320 --> 00:33:33,160 Speaker 1: really interesting to see the way that you know, the 541 00:33:33,680 --> 00:33:37,720 Speaker 1: that like viruses, like being introduced to a virus isn't 542 00:33:37,760 --> 00:33:41,719 Speaker 1: always bad. Sometimes it depends on the timing of the virus. 543 00:33:41,760 --> 00:33:44,280 Speaker 1: And then sometimes there can be a virus that actually 544 00:33:44,320 --> 00:33:49,600 Speaker 1: aids in our evolution. But then again, I'm not suggesting 545 00:33:49,640 --> 00:33:52,800 Speaker 1: that you go out and like French kiss someone who 546 00:33:52,880 --> 00:33:56,840 Speaker 1: has COVID or the flu, because most times, most times 547 00:33:56,840 --> 00:34:01,040 Speaker 1: that we encounter viruses, it's not necessarily going to be 548 00:34:01,160 --> 00:34:03,920 Speaker 1: a good thing. It might not hurt us that badly, 549 00:34:04,000 --> 00:34:06,600 Speaker 1: but it's certainly not gonna, you know, be the next 550 00:34:06,600 --> 00:34:09,600 Speaker 1: stage in human evolution. But if that happens enough, like 551 00:34:10,120 --> 00:34:13,640 Speaker 1: I think just the scale of evolution of millions of 552 00:34:13,719 --> 00:34:16,840 Speaker 1: years of this happening, you know, once in a while 553 00:34:16,880 --> 00:34:21,359 Speaker 1: there will actually be a useful mutation caused by this 554 00:34:21,520 --> 00:34:24,840 Speaker 1: viral DNA, which again, it's it's really interesting when like 555 00:34:25,719 --> 00:34:29,600 Speaker 1: that RNA and DNA essentially can like float around and 556 00:34:29,640 --> 00:34:34,320 Speaker 1: then just be absorbed into the cell and then whoop, 557 00:34:34,480 --> 00:34:36,600 Speaker 1: now it's part of our DNA. It's so weird. That 558 00:34:36,680 --> 00:34:39,279 Speaker 1: doesn't seem like that should be how it works, right, 559 00:34:39,360 --> 00:34:43,320 Speaker 1: that there can be free floating uh, you know, RNA 560 00:34:43,440 --> 00:34:46,000 Speaker 1: or DNA that we can actually incorporate into our own 561 00:34:46,040 --> 00:34:49,880 Speaker 1: genome and then pass on through our reproductive cells. That 562 00:34:50,239 --> 00:34:53,920 Speaker 1: seems like that should not work, but it does, and 563 00:34:53,960 --> 00:34:57,160 Speaker 1: that's probably I mean, that's like we're getting into sort 564 00:34:57,160 --> 00:34:59,239 Speaker 1: of the origin of life, right like where you have 565 00:34:59,360 --> 00:35:04,000 Speaker 1: these free floating strands of proteins that one you know, 566 00:35:04,239 --> 00:35:07,319 Speaker 1: glob absorbs another glob and now it's become a more 567 00:35:07,360 --> 00:35:11,040 Speaker 1: complex glob that has proteins that can start to actually 568 00:35:11,320 --> 00:35:15,719 Speaker 1: construct new proteins, which is, you know, so hard for 569 00:35:15,800 --> 00:35:18,760 Speaker 1: me to wrap my head around how that started. 570 00:35:18,400 --> 00:35:20,600 Speaker 2: But and so hard for all of us, and I 571 00:35:20,640 --> 00:35:25,040 Speaker 2: think science in general were hesitant to accept ideas, which 572 00:35:25,080 --> 00:35:29,239 Speaker 2: is awesome, right, That's what makes science unique in that 573 00:35:29,320 --> 00:35:35,360 Speaker 2: we consider new hypotheses and theories, but we have to 574 00:35:35,400 --> 00:35:37,880 Speaker 2: have lots of evidence. And one of the really cool 575 00:35:37,920 --> 00:35:41,560 Speaker 2: stories about that, of course, is our own mitochondria. This 576 00:35:41,680 --> 00:35:45,439 Speaker 2: story started a very long time ago where people started wondering, weight, 577 00:35:45,680 --> 00:35:48,640 Speaker 2: what's up with this mitochondria? The powerhouse, right, the cells 578 00:35:48,760 --> 00:35:51,560 Speaker 2: like ourselves, didn't function without them because they're what converts 579 00:35:51,600 --> 00:35:55,480 Speaker 2: the sugar into energy. But they're weirdos. They don't seem 580 00:35:55,520 --> 00:35:58,760 Speaker 2: to belong in a cell. And for the long time, 581 00:35:59,719 --> 00:36:03,719 Speaker 2: some scientists were very curious about this and saying, wait, 582 00:36:03,760 --> 00:36:06,239 Speaker 2: there's something different, and other folks were like, no, no, no, no, 583 00:36:06,400 --> 00:36:08,359 Speaker 2: you're what are you talking about? That's weird, you know. 584 00:36:08,680 --> 00:36:13,000 Speaker 2: And for a long time, the the science behind my 585 00:36:13,160 --> 00:36:17,279 Speaker 2: country where they came from, was ignored. But now we 586 00:36:17,480 --> 00:36:22,080 Speaker 2: understand that they are very different. The mitochondria as an organelle, 587 00:36:22,239 --> 00:36:26,480 Speaker 2: and you know, the theory is that they came from microbes. 588 00:36:26,520 --> 00:36:30,719 Speaker 2: So if we had never incorporated this microbe, this other 589 00:36:31,640 --> 00:36:35,759 Speaker 2: you know, into a cell, the complex cells with the 590 00:36:35,880 --> 00:36:40,080 Speaker 2: U carry outs would never have evolved, which just so 591 00:36:40,680 --> 00:36:46,560 Speaker 2: mind blowing. I mean, the whole idea of good versus 592 00:36:46,600 --> 00:36:50,600 Speaker 2: bad is a thing, you know, right, like the story 593 00:36:50,640 --> 00:36:53,400 Speaker 2: of the Turkey vultures. We talk about vultures because they 594 00:36:53,440 --> 00:36:54,160 Speaker 2: are awesome. 595 00:36:54,440 --> 00:36:57,279 Speaker 1: I mean I love them so yes, absolutely. 596 00:36:56,760 --> 00:36:58,920 Speaker 2: They're amazing. I mean, like they stick their head in 597 00:36:59,000 --> 00:37:01,600 Speaker 2: the grossest nest, the stuff, which we know is full 598 00:37:01,640 --> 00:37:04,520 Speaker 2: of bacteria. And if we think about sticking our head 599 00:37:04,560 --> 00:37:07,000 Speaker 2: into a dead body and eating it, of course we 600 00:37:07,080 --> 00:37:10,040 Speaker 2: think everything in there, all that bacteria that's rotting it, 601 00:37:10,040 --> 00:37:14,720 Speaker 2: it's got to be awful. But yet they don't get sick, right, 602 00:37:15,480 --> 00:37:17,840 Speaker 2: they don't. They survive this stuff and they don't have 603 00:37:17,880 --> 00:37:23,320 Speaker 2: any food poisoning and wow. And so a scientist decided 604 00:37:23,400 --> 00:37:26,360 Speaker 2: to investigate that, like he's like, we've got to understand 605 00:37:26,400 --> 00:37:30,600 Speaker 2: what's going into their body. And so he took a 606 00:37:30,600 --> 00:37:34,200 Speaker 2: bunch of dead vultures. Sadly, there were a number of 607 00:37:34,320 --> 00:37:37,759 Speaker 2: vultures that he swabbed their faces and their necks, and 608 00:37:37,800 --> 00:37:42,160 Speaker 2: there he found like over seven hundred different bacterial species 609 00:37:42,239 --> 00:37:45,799 Speaker 2: on them. Wait seven hundred can you imagine? And some 610 00:37:45,840 --> 00:37:49,960 Speaker 2: of those were like really really intense. And he's like, okay, 611 00:37:50,000 --> 00:37:52,960 Speaker 2: so what's going in their mouths, you know, is whatever's 612 00:37:52,960 --> 00:37:56,120 Speaker 2: on their face and lo and behold when he looks 613 00:37:56,160 --> 00:38:01,360 Speaker 2: in their guts, there's about seventy over just over set species. 614 00:38:01,640 --> 00:38:06,240 Speaker 2: Like that's huge, and so I how did that happen? 615 00:38:06,760 --> 00:38:09,600 Speaker 2: You know? And what's going on that we don't know? Right? 616 00:38:09,800 --> 00:38:12,640 Speaker 2: That is such new science. We don't know. But what's 617 00:38:12,680 --> 00:38:14,960 Speaker 2: intriguing to think about is the ones that are in 618 00:38:15,000 --> 00:38:18,520 Speaker 2: the guts are the ones that we would freak out 619 00:38:18,560 --> 00:38:20,520 Speaker 2: if they were in our guts. Like there's flesh eating 620 00:38:20,600 --> 00:38:23,279 Speaker 2: bacteria in there, there's ecola, there's this stuff. We're like, 621 00:38:23,320 --> 00:38:26,880 Speaker 2: whoa get away from us? Right, But yet they're surviving 622 00:38:26,920 --> 00:38:30,920 Speaker 2: and thriving in there, and we would assume that that's terrible, 623 00:38:30,920 --> 00:38:34,480 Speaker 2: but maybe not, you know, maybe they're actually supporting each other. 624 00:38:35,560 --> 00:38:38,440 Speaker 1: Yeah, now, I mean that is what is so interesting, right, Like, 625 00:38:38,520 --> 00:38:44,600 Speaker 1: you can have these very complex symbiotic relationships, and symbiosis 626 00:38:45,520 --> 00:38:49,839 Speaker 1: is not always good and it's not always bad, right Like, 627 00:38:49,880 --> 00:38:55,440 Speaker 1: Symbiosis just describes a close uh, basically a ballet between 628 00:38:55,480 --> 00:39:00,320 Speaker 1: two species. It could be a parasite and a ghost, 629 00:39:00,560 --> 00:39:05,000 Speaker 1: or it could be a mutualistic relationship. And sometimes these 630 00:39:05,040 --> 00:39:08,560 Speaker 1: relationships can like change over time, right, something that was 631 00:39:08,760 --> 00:39:13,280 Speaker 1: once like maybe at some point in the vulture's evolutionary 632 00:39:13,360 --> 00:39:17,000 Speaker 1: history these bacteria did harm them, and then over time 633 00:39:18,000 --> 00:39:22,759 Speaker 1: they evolved to coexist in a way where the bacteria 634 00:39:22,800 --> 00:39:26,839 Speaker 1: were able to survive, but so was the vulture. And 635 00:39:27,000 --> 00:39:30,080 Speaker 1: I mean it's so interesting because I mean, I do 636 00:39:30,160 --> 00:39:32,319 Speaker 1: I love vultures, and I love how like all of 637 00:39:32,320 --> 00:39:35,799 Speaker 1: the things that we see about them that seems to 638 00:39:35,840 --> 00:39:38,320 Speaker 1: make them gross, right, Like they have these bald heads 639 00:39:38,320 --> 00:39:41,320 Speaker 1: and it's like, oh, that's that's gross looking. That's for hygiene. 640 00:39:41,360 --> 00:39:44,480 Speaker 1: That's so blood and stuff doesn't get stuck to their feathers. 641 00:39:44,880 --> 00:39:47,120 Speaker 1: And then they poop on themselves. They poop on their 642 00:39:47,200 --> 00:39:50,000 Speaker 1: legs and for us that'd be like the most gross 643 00:39:50,040 --> 00:39:52,719 Speaker 1: thing you could do, But that's also for hygiene. They 644 00:39:52,760 --> 00:39:55,480 Speaker 1: have this very like they like bird poop in general 645 00:39:55,600 --> 00:39:59,040 Speaker 1: is a combination of urine and feces typically, and so 646 00:39:59,239 --> 00:40:02,560 Speaker 1: like the turepoop has this very it's very acidic, and 647 00:40:02,600 --> 00:40:05,799 Speaker 1: so it actually cleans their legs. And so it's like 648 00:40:05,840 --> 00:40:08,759 Speaker 1: these things that we would consider disgusting about them, right 649 00:40:08,800 --> 00:40:11,960 Speaker 1: Like they're eating they're eating a corpse. It's usually a 650 00:40:12,040 --> 00:40:16,240 Speaker 1: rotting cadaver, or it's it's really disgusting. Well, they're actually 651 00:40:16,280 --> 00:40:21,440 Speaker 1: taking a lot of like bacteria and nasty things out 652 00:40:21,480 --> 00:40:27,000 Speaker 1: of the environment and then converting it into food, containing 653 00:40:27,040 --> 00:40:30,680 Speaker 1: it and expelling it in a way that is less 654 00:40:30,680 --> 00:40:34,640 Speaker 1: harmful to other animals, to other to the environment. So 655 00:40:34,640 --> 00:40:38,799 Speaker 1: it's like, you know, these are actually amazing, Like we 656 00:40:38,840 --> 00:40:41,440 Speaker 1: can think of them as like the sanitation experts of 657 00:40:41,520 --> 00:40:44,680 Speaker 1: the animal kingdom. So everything that seems gross about them 658 00:40:44,680 --> 00:40:49,399 Speaker 1: to us is actually this process of taking these bad 659 00:40:49,480 --> 00:40:52,359 Speaker 1: things and then turning it into a process that like 660 00:40:52,480 --> 00:40:56,799 Speaker 1: works for them and then is helpful for preventing the 661 00:40:56,840 --> 00:40:58,640 Speaker 1: spread of disease and other animals. 662 00:40:59,000 --> 00:41:00,400 Speaker 2: We should be thinking them every. 663 00:41:00,320 --> 00:41:02,520 Speaker 1: Day, I personally do. 664 00:41:03,080 --> 00:41:09,000 Speaker 2: I realized I misspoke. When Gary the scientist Gary Graves 665 00:41:09,200 --> 00:41:12,319 Speaker 2: studied the vultures, he found over five hundred species on 666 00:41:12,360 --> 00:41:17,840 Speaker 2: their heads. We get so many. You know, what we 667 00:41:17,960 --> 00:41:20,080 Speaker 2: keep kind of coming back to is this idea of 668 00:41:20,280 --> 00:41:25,680 Speaker 2: evolution and you know, microbes and germs and all of 669 00:41:25,719 --> 00:41:28,839 Speaker 2: those things that we see is so bad. They're bad 670 00:41:29,000 --> 00:41:35,960 Speaker 2: for individuals, yes, but for populations it's different, you know, Yeah, 671 00:41:36,160 --> 00:41:39,960 Speaker 2: And so it's interesting to you know, our perspective as 672 00:41:40,000 --> 00:41:43,359 Speaker 2: individuals is that these things are bad because they can 673 00:41:43,440 --> 00:41:47,760 Speaker 2: kill individuals. But if we look in the evolutionary scope, 674 00:41:48,719 --> 00:41:52,000 Speaker 2: that's different, right in terms of the diversity that we 675 00:41:52,080 --> 00:41:56,279 Speaker 2: have on the planet. They've driven this evolution, and that's 676 00:41:56,480 --> 00:42:01,880 Speaker 2: just a mind boggling idea. 677 00:42:00,320 --> 00:42:04,759 Speaker 1: Right, Yeah, And without that diversity, I mean, what's this 678 00:42:04,840 --> 00:42:07,120 Speaker 1: is what's interesting, right, is because we have all sorts 679 00:42:07,160 --> 00:42:11,359 Speaker 1: of different selective pressures, from the very small like bacteria 680 00:42:11,640 --> 00:42:15,600 Speaker 1: and viruses, to the very large like a meteor hitting 681 00:42:15,680 --> 00:42:20,160 Speaker 1: the earth and changing the climate. And we can't like, 682 00:42:20,160 --> 00:42:24,640 Speaker 1: like the the fact that like bacteria and viruses have 683 00:42:24,760 --> 00:42:28,120 Speaker 1: driven this diversification of species, right, Like you know, you 684 00:42:28,120 --> 00:42:30,200 Speaker 1: would think like, well, so what right, it causes a 685 00:42:30,200 --> 00:42:32,840 Speaker 1: lot of suffering. So it's not they're not really good 686 00:42:32,920 --> 00:42:37,239 Speaker 1: to have. But because you have such a diversity of species, 687 00:42:37,400 --> 00:42:41,560 Speaker 1: then life can survive things like the climate suddenly changing. 688 00:42:41,840 --> 00:42:44,080 Speaker 1: A metea is striking their earth and causing because now 689 00:42:44,080 --> 00:42:48,120 Speaker 1: you have more of a like a genetic library for 690 00:42:48,280 --> 00:42:50,719 Speaker 1: these different animals. And so you're going to have the 691 00:42:50,880 --> 00:42:54,080 Speaker 1: mass extinction of a lot of animals, but you're going 692 00:42:54,120 --> 00:42:59,400 Speaker 1: to have just enough that have the ability to survive this. 693 00:42:59,600 --> 00:43:03,080 Speaker 1: And so much of that is driven by microbes, by 694 00:43:03,120 --> 00:43:05,600 Speaker 1: things that are things that are harmful and bad but 695 00:43:05,760 --> 00:43:08,560 Speaker 1: have driven this diversification of species that they actually are 696 00:43:08,600 --> 00:43:12,560 Speaker 1: able to survive, you know, devastating events. Maybe not on 697 00:43:12,600 --> 00:43:16,200 Speaker 1: the individual level, which is sad for the individual of course, 698 00:43:16,360 --> 00:43:19,719 Speaker 1: but in terms of like just life on Earth, like, 699 00:43:19,840 --> 00:43:24,879 Speaker 1: viruses and bacteria are not necessarily bad for life on 700 00:43:24,920 --> 00:43:29,200 Speaker 1: earth like for individual lives. Yes, and so again, keep 701 00:43:29,360 --> 00:43:32,920 Speaker 1: washing your hands, keep getting vaccinated. I'm not saying on 702 00:43:32,960 --> 00:43:36,320 Speaker 1: an individual level it's good for us to get walloped 703 00:43:36,360 --> 00:43:39,759 Speaker 1: by the flu or whatever. But yeah, in terms of 704 00:43:40,080 --> 00:43:44,879 Speaker 1: just general life on Earth, these relationships that we have 705 00:43:45,120 --> 00:43:50,200 Speaker 1: with with pathogens is actually really complex and it's not. 706 00:43:50,360 --> 00:43:55,760 Speaker 2: All bad exactly. And there's the whole, the whole idea 707 00:43:55,800 --> 00:44:00,759 Speaker 2: that we've lumped all microbes into this bad category. You know, 708 00:44:00,800 --> 00:44:03,120 Speaker 2: it's very easy for us too, because we can't see them, 709 00:44:03,200 --> 00:44:05,200 Speaker 2: and when we can't see them, we don't understand them. 710 00:44:05,600 --> 00:44:09,280 Speaker 2: And that's why I'm so passionate about learning and teaching 711 00:44:09,320 --> 00:44:13,480 Speaker 2: about this because the more we know, Wow, it opens 712 00:44:13,600 --> 00:44:16,920 Speaker 2: our eyes to so many things that we didn't understand. 713 00:44:17,160 --> 00:44:20,440 Speaker 2: This complexity that's there, These microbes that are in our 714 00:44:20,440 --> 00:44:24,760 Speaker 2: bodies that we wouldn't survive without you know. That's nest. 715 00:44:25,600 --> 00:44:26,520 Speaker 2: It's mind blowing. 716 00:44:26,760 --> 00:44:30,120 Speaker 1: It's something you can't even if you can't directly see it, 717 00:44:30,120 --> 00:44:32,759 Speaker 1: it's something you can feel. If you've ever had a 718 00:44:32,880 --> 00:44:39,280 Speaker 1: bad stomach flu, which I have had recently, and essentially 719 00:44:39,280 --> 00:44:41,719 Speaker 1: what happens with the stomach flu is your body is 720 00:44:41,760 --> 00:44:45,200 Speaker 1: like hits the eject button because something is in there 721 00:44:45,400 --> 00:44:50,040 Speaker 1: that's that's bad. Sometimes it's a virus, sometimes it's food poisoning, 722 00:44:51,280 --> 00:44:55,640 Speaker 1: and so your body is like emergency, We've got to evacuate. 723 00:44:56,000 --> 00:44:58,000 Speaker 1: We've got to get rid of this. So you're gonna 724 00:44:58,080 --> 00:45:01,920 Speaker 1: vomit and you're gonna have diarrhea. Uh. And so that's 725 00:45:01,960 --> 00:45:04,000 Speaker 1: why it's I mean, the number one thing when you 726 00:45:04,040 --> 00:45:08,520 Speaker 1: have a stomach flu or food poisoning is hydration because 727 00:45:08,600 --> 00:45:12,080 Speaker 1: like you're losing a lot of fluid food, you don't 728 00:45:12,080 --> 00:45:14,879 Speaker 1: have to worry about as much. You will you will 729 00:45:14,880 --> 00:45:17,040 Speaker 1: be hungry when you're hungry, it's going to take a 730 00:45:17,080 --> 00:45:19,439 Speaker 1: little while. But yeah, so you should hydrate. But your 731 00:45:19,560 --> 00:45:22,279 Speaker 1: your body is doing something important. It is it is 732 00:45:22,360 --> 00:45:26,480 Speaker 1: getting rid of something that it thinks is really dangerous 733 00:45:26,520 --> 00:45:29,600 Speaker 1: and could cut and could really severely hurt you. Is 734 00:45:29,640 --> 00:45:33,520 Speaker 1: it always right? Maybe not, but it's it's doing the 735 00:45:33,520 --> 00:45:36,560 Speaker 1: best job it can in terms of gauging. Okay, when 736 00:45:36,600 --> 00:45:40,480 Speaker 1: do we need to just eject everything? But what happens 737 00:45:40,560 --> 00:45:45,279 Speaker 1: is you actually lose like through that injection, Like after that, 738 00:45:45,360 --> 00:45:48,040 Speaker 1: you might find that sometimes you get more kind of 739 00:45:48,120 --> 00:45:51,439 Speaker 1: you feel kind of yucky a while after, like after 740 00:45:51,480 --> 00:45:53,920 Speaker 1: you're done with the stomach flu, after you're done with 741 00:45:53,960 --> 00:45:56,760 Speaker 1: the food poisoning, you still kind of maybe get maybe 742 00:45:56,800 --> 00:46:00,239 Speaker 1: some like indigestion or some stomach issues. And it's like, well, 743 00:46:00,280 --> 00:46:03,040 Speaker 1: because you flushed out a lot of good bacteria as well, 744 00:46:03,640 --> 00:46:07,600 Speaker 1: and which is why you know, the immune response has 745 00:46:07,640 --> 00:46:12,520 Speaker 1: to be so delicate and not always go off all 746 00:46:12,640 --> 00:46:16,480 Speaker 1: the time whenever you are infected with them, you know, 747 00:46:16,560 --> 00:46:21,279 Speaker 1: a tiny pathogen like because that that flushing out, you 748 00:46:21,360 --> 00:46:24,600 Speaker 1: are flushing out also like good bacteria. So it's you know, 749 00:46:24,640 --> 00:46:28,239 Speaker 1: it's good to like uh sort of uh try to 750 00:46:28,600 --> 00:46:31,560 Speaker 1: you know, once you start to rehydrate and eat food 751 00:46:31,760 --> 00:46:35,319 Speaker 1: and stuff and naturally, your your gut floora will repopulate. 752 00:46:35,400 --> 00:46:37,960 Speaker 1: So it's not something you have to panic about or 753 00:46:38,000 --> 00:46:40,920 Speaker 1: anything like that. But it is really interesting and it's 754 00:46:40,960 --> 00:46:45,440 Speaker 1: also it's so interesting these there are things in medicine 755 00:46:45,440 --> 00:46:48,799 Speaker 1: where we recognize right the power of this gut bacteria. 756 00:46:48,920 --> 00:46:53,000 Speaker 1: So we have things like fecal transplants, which sounds horrifying, 757 00:46:54,440 --> 00:46:58,319 Speaker 1: sounds sounds not like something that you would want to 758 00:46:58,360 --> 00:47:01,319 Speaker 1: have happened, but it is apparently something that can be 759 00:47:01,360 --> 00:47:05,440 Speaker 1: really important in terms of helping repopulate someone's gut with 760 00:47:05,560 --> 00:47:09,879 Speaker 1: good bacteria, with something that can actually help them help 761 00:47:09,920 --> 00:47:12,040 Speaker 1: a person like when you digest food. It can also 762 00:47:12,080 --> 00:47:16,480 Speaker 1: protect you from other bacteria because bacteria, like any organism, 763 00:47:16,880 --> 00:47:19,279 Speaker 1: are in competition with each other. So if you have 764 00:47:19,440 --> 00:47:23,840 Speaker 1: a less harmful bacteria that is populating your gut, it 765 00:47:23,880 --> 00:47:26,880 Speaker 1: will try to compete with and interfere with bacteria that 766 00:47:26,960 --> 00:47:30,760 Speaker 1: might make you sick. So yeah, like bacteria is often 767 00:47:30,840 --> 00:47:35,480 Speaker 1: our friend, it's just sometimes when it isn't, it's really noticeable. 768 00:47:36,080 --> 00:47:40,720 Speaker 2: Yeah, and it's nasty discussing. Yeah, fecal transplants are just amazing. 769 00:47:40,840 --> 00:47:44,200 Speaker 2: I just I can hardly believe that that works, but 770 00:47:44,280 --> 00:47:47,960 Speaker 2: it does. And once I met some folks who have 771 00:47:48,400 --> 00:47:54,560 Speaker 2: had fecal transplants and successfully, you know, cure m it's 772 00:47:54,640 --> 00:47:59,919 Speaker 2: just amazing what they what they can do. So when 773 00:48:00,000 --> 00:48:03,200 Speaker 2: one of the things that amazes me is that even 774 00:48:03,280 --> 00:48:07,040 Speaker 2: bacteria that we see as the bad guys like staphylococcus, right, 775 00:48:07,239 --> 00:48:12,080 Speaker 2: which can be really a huge problem. But staff itself 776 00:48:12,520 --> 00:48:17,680 Speaker 2: is infected. Some staff can exist on us in a 777 00:48:18,239 --> 00:48:23,240 Speaker 2: very healthy way, and other staff that have has genetic 778 00:48:23,360 --> 00:48:26,520 Speaker 2: material that's we're not really sure how it gets in there, 779 00:48:26,800 --> 00:48:30,240 Speaker 2: but it has. It has additional genetic material from another 780 00:48:30,400 --> 00:48:34,239 Speaker 2: organism that in fact is like it in self is infected. 781 00:48:34,560 --> 00:48:36,960 Speaker 2: So we don't think about the fact that that all 782 00:48:37,040 --> 00:48:40,239 Speaker 2: of these microupes are in their own world dealing with 783 00:48:40,360 --> 00:48:43,560 Speaker 2: infections of themselves just wind. 784 00:48:43,360 --> 00:48:46,200 Speaker 1: Blowing when you zoom out more like it's easier to 785 00:48:46,320 --> 00:48:49,440 Speaker 1: comprehend that where when you have a mosquito, Mosquitoes do 786 00:48:49,520 --> 00:48:54,000 Speaker 1: not make us sick, right, Mosquitoes are would actually be 787 00:48:54,880 --> 00:49:01,719 Speaker 1: relatively harmless. They are parasites, but they would if if 788 00:49:01,760 --> 00:49:09,320 Speaker 1: not for pathogens that actually infect the mosquitoes. Mosquitoes themselves 789 00:49:09,400 --> 00:49:13,920 Speaker 1: would be pretty harmless to like a human, but because 790 00:49:13,960 --> 00:49:20,400 Speaker 1: they themselves can be infected with with pathogens with like 791 00:49:21,239 --> 00:49:23,920 Speaker 1: something that can actually be passed on to us, and 792 00:49:23,920 --> 00:49:26,799 Speaker 1: in fact that it's the whole reason that they will 793 00:49:26,840 --> 00:49:30,640 Speaker 1: infect the the the mosquito. The mosquito can then pass 794 00:49:30,719 --> 00:49:34,000 Speaker 1: something along to us and so something that we see 795 00:49:34,239 --> 00:49:38,000 Speaker 1: right like as this mosquito is like hurting us, it's like, well, 796 00:49:38,000 --> 00:49:40,480 Speaker 1: it's not really the mosquito itself, it's whatever has hitched 797 00:49:40,480 --> 00:49:43,480 Speaker 1: a ride on the mosquito. And then but then when 798 00:49:43,520 --> 00:49:46,000 Speaker 1: you of course, like you go and sort of like 799 00:49:46,120 --> 00:49:49,440 Speaker 1: all the evolutionary pressures and the sorts of like symbiotic 800 00:49:49,520 --> 00:49:53,759 Speaker 1: relationships that affect like like organisms, you know, macro organisms, 801 00:49:54,200 --> 00:49:57,600 Speaker 1: are those same things are happening on a microscopic level. 802 00:49:57,640 --> 00:50:01,279 Speaker 1: Like that is not my I don't talk about it 803 00:50:01,320 --> 00:50:03,320 Speaker 1: as much because it is not sort of my area 804 00:50:03,320 --> 00:50:06,160 Speaker 1: of expertise, but it is still really really interesting. 805 00:50:06,360 --> 00:50:09,320 Speaker 2: It is mind blowing. I came across a study of ticks, 806 00:50:10,000 --> 00:50:13,640 Speaker 2: same concept, where a tick doesn't ask to be infected 807 00:50:13,640 --> 00:50:16,480 Speaker 2: by lime disease. Right, that's not something they chose, right, 808 00:50:16,560 --> 00:50:22,640 Speaker 2: they are infected. There's an amazing study of a lizard 809 00:50:23,160 --> 00:50:27,680 Speaker 2: out in the western United States. Who if an infected 810 00:50:27,840 --> 00:50:33,040 Speaker 2: tick bites this lizard. We don't understand everything that's going 811 00:50:33,080 --> 00:50:36,760 Speaker 2: on here, but the tick when it leaves the lizard 812 00:50:37,320 --> 00:50:40,480 Speaker 2: no longer has carries lime disease. 813 00:50:40,920 --> 00:50:42,399 Speaker 1: Oh that's so interesting. 814 00:50:42,080 --> 00:50:48,560 Speaker 2: So amazing, Right, So something's happening when the blood from 815 00:50:48,600 --> 00:50:53,000 Speaker 2: the lizard enters the foregut of the tick that's affecting 816 00:50:53,400 --> 00:50:58,960 Speaker 2: that disease causing microbe. Just mind blowing to think about it. 817 00:50:58,960 --> 00:51:00,920 Speaker 2: You know, we think of ticks they're terrible, awful, but 818 00:51:01,040 --> 00:51:04,600 Speaker 2: just like mosquitoes, they and of themselves don't cause that 819 00:51:04,719 --> 00:51:05,480 Speaker 2: much damage. 820 00:51:05,800 --> 00:51:10,120 Speaker 1: But yeah, yeah, but they are too convenient of a 821 00:51:10,160 --> 00:51:18,240 Speaker 1: little taxi, uh for like they like mosquitoes, ticks, fleas, rats, 822 00:51:18,280 --> 00:51:20,520 Speaker 1: you know, all these these little animals that we think 823 00:51:20,520 --> 00:51:23,320 Speaker 1: of as you know, gross, like you know, plague bearing animals. 824 00:51:23,320 --> 00:51:25,719 Speaker 1: It's just because they're little taxis, right Like, they get 825 00:51:25,719 --> 00:51:28,279 Speaker 1: around a lot. They're easy to hitch your right on, 826 00:51:28,880 --> 00:51:31,360 Speaker 1: and you know, I mean it's like a flea hitching 827 00:51:31,360 --> 00:51:34,600 Speaker 1: your right on a rat. But then you know the 828 00:51:34,600 --> 00:51:38,080 Speaker 1: the bubonic plague hitching your right on the flea. It's 829 00:51:38,200 --> 00:51:43,359 Speaker 1: it's these these other intermediary organisms have no idea that 830 00:51:43,400 --> 00:51:47,160 Speaker 1: they are little cab drivers for disease. And it's not 831 00:51:47,200 --> 00:51:50,360 Speaker 1: really their fault. Uh So it's I mean, it's not 832 00:51:50,440 --> 00:51:52,560 Speaker 1: even the disease's fault when you get down to it. 833 00:51:53,000 --> 00:51:55,920 Speaker 1: But you know, it's just it it is really interesting. 834 00:51:57,280 --> 00:51:59,800 Speaker 1: Before we go, I guess I just wanted to circle 835 00:51:59,800 --> 00:52:03,759 Speaker 1: back to kind of the initial question that we talked about, like, 836 00:52:03,800 --> 00:52:07,200 Speaker 1: why do you think so called gross stuff is so 837 00:52:07,360 --> 00:52:08,520 Speaker 1: fascinating to people? 838 00:52:08,600 --> 00:52:08,759 Speaker 2: Right? 839 00:52:08,800 --> 00:52:12,520 Speaker 1: Because I certainly find it fascinating. I have never grown 840 00:52:12,520 --> 00:52:16,719 Speaker 1: out of finding poop and puke and mucus to be 841 00:52:16,840 --> 00:52:21,839 Speaker 1: really interesting. Now I don't want to necessarily see it 842 00:52:21,960 --> 00:52:24,920 Speaker 1: much in real life, right, Like, if I step on 843 00:52:25,080 --> 00:52:27,560 Speaker 1: dog poop, I'm not like, well, this is great. But 844 00:52:28,239 --> 00:52:31,520 Speaker 1: in terms of being interested in stories about it, being 845 00:52:31,560 --> 00:52:33,399 Speaker 1: interested in the science of it, what do you think 846 00:52:33,560 --> 00:52:38,040 Speaker 1: is so compelling about it that kids and adults, even 847 00:52:38,040 --> 00:52:40,640 Speaker 1: adults who don't want to admit it, finds so interesting. 848 00:52:41,160 --> 00:52:44,400 Speaker 2: I think it's the questions, because I think questions are 849 00:52:45,080 --> 00:52:48,279 Speaker 2: or and or curiosity all to linked together. That's what 850 00:52:48,360 --> 00:52:51,560 Speaker 2: drives learning, and the human mind wants to learn, right, 851 00:52:52,040 --> 00:52:55,040 Speaker 2: We're innately driven to learn and learn and learn. And 852 00:52:55,080 --> 00:52:59,160 Speaker 2: when we find something such as poop or blood or 853 00:52:59,160 --> 00:53:02,200 Speaker 2: something like that that society says, oh, no, gross, don't 854 00:53:02,200 --> 00:53:04,759 Speaker 2: look at that, don't pay attention to it, We're like, wait, 855 00:53:04,760 --> 00:53:08,239 Speaker 2: what you know? I want to know more? And the 856 00:53:08,280 --> 00:53:10,520 Speaker 2: first question is why why am I not supposed to 857 00:53:10,520 --> 00:53:12,600 Speaker 2: look at that? Right? It's a. It's a kind of 858 00:53:12,600 --> 00:53:16,840 Speaker 2: a taboo subject, but why, And then that just drives 859 00:53:16,920 --> 00:53:19,799 Speaker 2: us to learn more and more the human mind. It's 860 00:53:19,760 --> 00:53:22,520 Speaker 2: an amazing thing when we ask those questions, when we 861 00:53:22,520 --> 00:53:25,520 Speaker 2: look a little closer, that's when we discover all of 862 00:53:25,560 --> 00:53:27,480 Speaker 2: this that we've been talking about today was all driven 863 00:53:27,480 --> 00:53:32,160 Speaker 2: by questions. Somebody's question about something weird that happened, that 864 00:53:32,200 --> 00:53:35,680 Speaker 2: they observed, and they dug a little deeper, and in 865 00:53:35,719 --> 00:53:38,399 Speaker 2: the end, our minds get blown again and again as 866 00:53:38,400 --> 00:53:41,480 Speaker 2: we look at the animal kingdom right as we discover 867 00:53:41,920 --> 00:53:44,719 Speaker 2: these little bits and pieces. And what I'm so fascinated 868 00:53:44,760 --> 00:53:46,600 Speaker 2: with is the fact that every single one of us 869 00:53:46,640 --> 00:53:48,640 Speaker 2: can do that every day. All we have to do 870 00:53:48,800 --> 00:53:51,160 Speaker 2: is look and start asking questions. 871 00:53:52,400 --> 00:53:56,080 Speaker 1: Absolutely, Well, thank you so much for coming on.
