1 00:00:07,280 --> 00:00:10,640 Speaker 1: Welcome to Creature Feature production of I Heart Radio. I'm 2 00:00:10,680 --> 00:00:14,440 Speaker 1: your host of Many Parasites, Katie Golden. I studied psychology 3 00:00:14,440 --> 00:00:19,279 Speaker 1: and evolutionary biology, and today on the show listener questions again. 4 00:00:19,800 --> 00:00:22,360 Speaker 1: You guys send me in your questions and I love 5 00:00:22,440 --> 00:00:25,760 Speaker 1: to answer them, So let's scare right into it. I 6 00:00:25,800 --> 00:00:30,240 Speaker 1: guess I got some really good questions this time, so 7 00:00:30,280 --> 00:00:33,440 Speaker 1: I'm very excited to answer them. All Right, So I 8 00:00:33,520 --> 00:00:36,159 Speaker 1: got some emails, I got some tweets. I'm going to 9 00:00:36,240 --> 00:00:40,240 Speaker 1: start off with an email from Rachel. My name is Rachel, 10 00:00:40,280 --> 00:00:42,480 Speaker 1: and I love your show. I've been a fan since 11 00:00:42,520 --> 00:00:44,720 Speaker 1: episode one and Creature Feature has been the highlight of 12 00:00:44,760 --> 00:00:47,040 Speaker 1: my week ever since. Thank you so much, You're so sweet. 13 00:00:47,200 --> 00:00:49,720 Speaker 1: As a result, I have become the person at work 14 00:00:49,760 --> 00:00:53,360 Speaker 1: that will randomly spout animal facts and conversation excellent. One. 15 00:00:53,440 --> 00:00:57,440 Speaker 1: Such a conversation resulted in a question, how do tis 16 00:00:58,000 --> 00:01:00,520 Speaker 1: where I lived? Ticks are constant problem? But how do 17 00:01:00,680 --> 00:01:02,960 Speaker 1: they get so prevalent? Like in order for a tick 18 00:01:03,000 --> 00:01:05,319 Speaker 1: to reach maturity, it needs to find an animal to 19 00:01:05,360 --> 00:01:08,080 Speaker 1: gorge itself on right, then it rides that animal to 20 00:01:08,200 --> 00:01:10,640 Speaker 1: who knows where. I know that there are male and 21 00:01:10,680 --> 00:01:13,000 Speaker 1: female ticks. How do they find each other? It would 22 00:01:13,000 --> 00:01:15,959 Speaker 1: seem like they're nutritional and reproductive needs are at odds 23 00:01:16,000 --> 00:01:20,679 Speaker 1: with each other. Second, I had a topic idea. Pride 24 00:01:20,680 --> 00:01:23,240 Speaker 1: Month is coming up, and I am transgender. I would 25 00:01:23,240 --> 00:01:25,560 Speaker 1: love to learn more about animals that have the ability 26 00:01:25,600 --> 00:01:28,399 Speaker 1: to change sex or mimic the opposite sex. I know 27 00:01:28,480 --> 00:01:32,080 Speaker 1: you have touched on it a little in the past, frogs, cuttlefish, etcetera. 28 00:01:32,200 --> 00:01:33,760 Speaker 1: I think it would be cool to learn about the 29 00:01:33,760 --> 00:01:36,959 Speaker 1: gender and sexual fluidity in nature. Anyways, thanks for making 30 00:01:37,000 --> 00:01:40,000 Speaker 1: a great show. Don't ever stop being you take care Rachel. Well, 31 00:01:40,040 --> 00:01:42,319 Speaker 1: thank you so much, Rachel for your kind words, and 32 00:01:42,319 --> 00:01:45,760 Speaker 1: you're great, You're great. Questions. First of all, I think 33 00:01:45,800 --> 00:01:48,480 Speaker 1: that sexual fluidity is a great idea for a show, 34 00:01:48,800 --> 00:01:51,200 Speaker 1: and I'd love to do an episode on that real soon, 35 00:01:51,800 --> 00:01:55,520 Speaker 1: just to quickly touch upon it. There are actually many 36 00:01:55,600 --> 00:02:00,000 Speaker 1: species of ray finn fish who are masters of sexual fluidity, 37 00:02:00,240 --> 00:02:05,120 Speaker 1: like clown fish. So with clownfish social structures, there are 38 00:02:05,160 --> 00:02:09,160 Speaker 1: a dominant females and breeding males in a hierarchy, but 39 00:02:09,280 --> 00:02:13,000 Speaker 1: when the dominant female dies, the dominant male will actually 40 00:02:13,040 --> 00:02:17,280 Speaker 1: become the new dominant female and undergo reproductive changes. To 41 00:02:17,320 --> 00:02:22,840 Speaker 1: become female in the hierarchy. I think it's important to 42 00:02:22,919 --> 00:02:25,720 Speaker 1: point out, and Rachel, I know that you're not saying this, 43 00:02:25,760 --> 00:02:28,760 Speaker 1: but I think whenever we talk about like, we kind 44 00:02:28,760 --> 00:02:32,359 Speaker 1: of make comparisons to human sexuality and sexuality and nature. 45 00:02:32,680 --> 00:02:36,560 Speaker 1: It's an important note that like animals, for the most part, 46 00:02:37,120 --> 00:02:39,320 Speaker 1: although well I'll talk about this little later, but for 47 00:02:39,440 --> 00:02:43,000 Speaker 1: the most part, generally speaking, animals don't really have a gender, 48 00:02:43,480 --> 00:02:47,040 Speaker 1: so to speak. So I bet if we do research 49 00:02:47,240 --> 00:02:52,360 Speaker 1: into intelligent animals, we may actually find some interesting information 50 00:02:52,440 --> 00:02:57,000 Speaker 1: on the animals concept of gender expression. But when we 51 00:02:57,080 --> 00:03:01,800 Speaker 1: talk about animals in general, like animal going through say 52 00:03:02,120 --> 00:03:05,040 Speaker 1: a change of sex, like a clown, which changing from 53 00:03:05,040 --> 00:03:10,079 Speaker 1: male sex to female sex. This is a physical, physiological process, 54 00:03:10,120 --> 00:03:15,280 Speaker 1: whereas in humans gender expression is it's different. I'm not 55 00:03:15,440 --> 00:03:18,720 Speaker 1: necessarily an expert on gender expression in humans, but I 56 00:03:18,720 --> 00:03:21,639 Speaker 1: think that for people it's both an internal and an 57 00:03:21,639 --> 00:03:27,160 Speaker 1: external experience. It's both social and deeply personal. So, like you, 58 00:03:27,160 --> 00:03:31,520 Speaker 1: you have your own personal concept of gender within yourself, 59 00:03:31,600 --> 00:03:35,400 Speaker 1: and then there's also socially constructed gender, and so all 60 00:03:35,440 --> 00:03:39,240 Speaker 1: of that interacts in a very complex way. And so 61 00:03:39,560 --> 00:03:42,800 Speaker 1: anytime we talk about animal sex like it it's it's 62 00:03:42,840 --> 00:03:46,480 Speaker 1: going to be very different from humans, but not completely. 63 00:03:46,560 --> 00:03:51,000 Speaker 1: Like it's not as if we can't enjoy seeing sort 64 00:03:51,040 --> 00:03:55,640 Speaker 1: of like the diversity of sexual changes in animals. And 65 00:03:55,920 --> 00:03:59,400 Speaker 1: you know, I do think it's interesting when people try 66 00:03:59,440 --> 00:04:03,480 Speaker 1: to just ify bigotry against trans people or sexual and 67 00:04:03,520 --> 00:04:07,280 Speaker 1: gender minorities by citing like, oh, it's not natural. And 68 00:04:07,400 --> 00:04:10,560 Speaker 1: people who say things like that tint to not know 69 00:04:10,800 --> 00:04:14,280 Speaker 1: anything about nature. I mean, when you look at nature, 70 00:04:14,640 --> 00:04:19,480 Speaker 1: it is so diverse when it comes to sex and reproduction. 71 00:04:20,000 --> 00:04:23,000 Speaker 1: So to say like, oh, well, this isn't natural, it's like, well, okay, 72 00:04:23,040 --> 00:04:26,320 Speaker 1: but nature has so much stuff going on when it 73 00:04:26,360 --> 00:04:29,360 Speaker 1: comes to sexual reproduction, Like, how can you say it's 74 00:04:29,360 --> 00:04:33,440 Speaker 1: not natural? You can't. There's nature has every type of 75 00:04:33,480 --> 00:04:37,000 Speaker 1: sexual reproduction you can think of, every type of sex, 76 00:04:37,600 --> 00:04:40,479 Speaker 1: every type of kinds of behavior. So to say like 77 00:04:40,520 --> 00:04:42,760 Speaker 1: this isn't natural, it's like, well, I mean, first of all, 78 00:04:42,800 --> 00:04:46,120 Speaker 1: who cares if it's not natural. We're humans. We have 79 00:04:46,400 --> 00:04:49,960 Speaker 1: televisions and medicine, which you could argue aren't natural either. 80 00:04:50,040 --> 00:04:53,640 Speaker 1: But secondly, it's just wrong. It's nature has no like 81 00:04:54,640 --> 00:04:59,680 Speaker 1: one type of sexuality. That's ridiculous in terms of actual 82 00:05:00,120 --> 00:05:04,520 Speaker 1: gender expression in animals. It's a much more complex question 83 00:05:04,920 --> 00:05:08,840 Speaker 1: than say like sexual fluidity in animals because you can 84 00:05:08,880 --> 00:05:12,080 Speaker 1: see you can look at a clown fish and see that, Okay, 85 00:05:12,160 --> 00:05:16,280 Speaker 1: so it goes under this hormonal change where you know, 86 00:05:16,360 --> 00:05:20,599 Speaker 1: a clown fish will like that situation I described, when 87 00:05:20,600 --> 00:05:23,640 Speaker 1: the dominant females die, the dominant male will undergo this 88 00:05:23,680 --> 00:05:29,280 Speaker 1: hormonal change and actually express uh female genitals. And so 89 00:05:29,360 --> 00:05:34,240 Speaker 1: that's an external physical change we can observe, so researchers 90 00:05:34,240 --> 00:05:39,599 Speaker 1: can actually observe that directly. But gender uh in humans 91 00:05:40,200 --> 00:05:43,360 Speaker 1: is an often not just a social experience, but an 92 00:05:43,360 --> 00:05:47,360 Speaker 1: internal experience. So we can't just ask an animal like like, 93 00:05:47,520 --> 00:05:50,960 Speaker 1: what what are your feelings on gender? Uh? What does 94 00:05:51,000 --> 00:05:53,919 Speaker 1: that mean to you? So it's very hard to study 95 00:05:54,000 --> 00:05:59,120 Speaker 1: that and say more intelligent animals like primates or dolphins 96 00:05:59,200 --> 00:06:02,680 Speaker 1: or elephants. But that's not to say that there have 97 00:06:02,760 --> 00:06:05,760 Speaker 1: been no attempts made to parse this issue out. So 98 00:06:06,040 --> 00:06:08,960 Speaker 1: there's this great article. I highly recommend you read the 99 00:06:09,000 --> 00:06:11,560 Speaker 1: whole article because it does a great job of explaining 100 00:06:11,600 --> 00:06:15,680 Speaker 1: all these things. Uh. It's in Sapiens Anthropology magazine by j. 101 00:06:15,880 --> 00:06:20,400 Speaker 1: Schwartz and Assistant Professor of Psychological Science, at Western Oregon University. 102 00:06:20,720 --> 00:06:24,280 Speaker 1: The article is called is Gender Unique to Humans? In 103 00:06:24,320 --> 00:06:27,000 Speaker 1: this article there is a description of a study at 104 00:06:27,040 --> 00:06:30,880 Speaker 1: Florida International University that looks at the behaviors of chimpanzees 105 00:06:30,920 --> 00:06:35,920 Speaker 1: and bonobo's, a couple of our closest primate relatives. Uh, 106 00:06:36,000 --> 00:06:39,920 Speaker 1: And they look at, well, could there be something like 107 00:06:40,160 --> 00:06:44,120 Speaker 1: gender expression in these primates? Could there be a social 108 00:06:44,560 --> 00:06:49,120 Speaker 1: concept of gender? And they found that in the wild, uh, 109 00:06:49,240 --> 00:06:54,040 Speaker 1: social grooming behavior differs by sex. Now, with that alone, 110 00:06:54,120 --> 00:06:57,640 Speaker 1: we still don't know whether this is like a gender 111 00:06:57,680 --> 00:07:01,279 Speaker 1: expression or what it is, because that could could be instinctive, 112 00:07:01,360 --> 00:07:05,200 Speaker 1: it could have all sorts of different explanations. But they 113 00:07:05,240 --> 00:07:10,280 Speaker 1: did find that in captivity social grooming behavior doesn't really 114 00:07:10,360 --> 00:07:14,600 Speaker 1: differ that much by sex, which seems to indicate that, 115 00:07:15,400 --> 00:07:19,120 Speaker 1: you know, these primates in the wild may have a 116 00:07:19,200 --> 00:07:23,960 Speaker 1: different culture than primates in captivity, where in the wild 117 00:07:24,000 --> 00:07:28,240 Speaker 1: they have a different social expectations for different genders when 118 00:07:28,240 --> 00:07:32,600 Speaker 1: it comes to grooming behaviors versus primates in captivity who 119 00:07:32,600 --> 00:07:35,760 Speaker 1: are cut off from that culture in the wild. Now, 120 00:07:36,440 --> 00:07:40,600 Speaker 1: this is not definitive because animals in captivity, as I 121 00:07:40,640 --> 00:07:43,320 Speaker 1: believe we've talked about on the show before, they are 122 00:07:43,960 --> 00:07:48,280 Speaker 1: in a very different circumstance. So because it's such a 123 00:07:48,360 --> 00:07:51,480 Speaker 1: strange environment for them to be in, and their stress 124 00:07:51,600 --> 00:07:55,160 Speaker 1: responses and all their social organization gets kind of like 125 00:07:55,280 --> 00:07:59,320 Speaker 1: messed up by being in this captive setting. It's hard 126 00:07:59,400 --> 00:08:03,760 Speaker 1: to say, well, is there's a difference because they're they're 127 00:08:03,880 --> 00:08:06,720 Speaker 1: sort of gender culture is different within captivity or is 128 00:08:06,720 --> 00:08:09,680 Speaker 1: it because they're stressed and other factors. I don't think 129 00:08:09,680 --> 00:08:12,680 Speaker 1: we really know yet, But this is really interesting to 130 00:08:12,760 --> 00:08:16,560 Speaker 1: me that we're starting to, you know, think about like, well, 131 00:08:16,840 --> 00:08:22,440 Speaker 1: you know, humans have a social gender construct and an 132 00:08:22,440 --> 00:08:26,440 Speaker 1: internal gender construct and uh, you know when we look 133 00:08:26,560 --> 00:08:30,320 Speaker 1: at animals, if we look at our closest relatives, I 134 00:08:30,360 --> 00:08:34,760 Speaker 1: don't think it's too far of a leap of logic 135 00:08:34,800 --> 00:08:38,200 Speaker 1: to think, well, maybe they may have something uh, you know, 136 00:08:38,640 --> 00:08:42,360 Speaker 1: while not similar to our concept of gender, maybe they 137 00:08:42,440 --> 00:08:45,120 Speaker 1: have something uh, and we just don't know. And I 138 00:08:45,160 --> 00:08:48,520 Speaker 1: think that's it's really interesting that we are starting to 139 00:08:48,559 --> 00:08:51,720 Speaker 1: look into that. Um. But yeah, it's very difficult to 140 00:08:51,800 --> 00:08:54,240 Speaker 1: research because, like I said, you know, gender is an 141 00:08:54,240 --> 00:08:58,560 Speaker 1: internal experience like um that that you feel inside, and 142 00:08:58,600 --> 00:09:01,920 Speaker 1: it's also an external experien that you learn from your culture. 143 00:09:02,080 --> 00:09:07,080 Speaker 1: So either question is quite difficult for researchers to answer 144 00:09:07,160 --> 00:09:10,600 Speaker 1: when looking at a like, say, a primate culture. But 145 00:09:10,640 --> 00:09:13,280 Speaker 1: we do know that primates do learn from each other, 146 00:09:13,360 --> 00:09:17,400 Speaker 1: and they seem to have different cultures. So you have, um, 147 00:09:17,440 --> 00:09:20,520 Speaker 1: you may have like a group of orangutans who use 148 00:09:20,760 --> 00:09:25,640 Speaker 1: specific tools to get termites or ants, where you don't 149 00:09:25,640 --> 00:09:29,720 Speaker 1: see that in other orienting groups. So it seems to 150 00:09:29,760 --> 00:09:33,560 Speaker 1: indicate that primates do learn from each other they could 151 00:09:33,600 --> 00:09:36,080 Speaker 1: form these cultures. So I think this is a really 152 00:09:36,120 --> 00:09:40,640 Speaker 1: interesting line of research. And so oh, as to your 153 00:09:40,720 --> 00:09:44,400 Speaker 1: other question, Rachel, how do ticks work? This is a 154 00:09:44,440 --> 00:09:47,760 Speaker 1: great question because it does. It does blow my mind 155 00:09:47,840 --> 00:09:51,160 Speaker 1: when we talk about parasites. I love parasites. I don't 156 00:09:51,240 --> 00:09:53,760 Speaker 1: obviously don't want ticks on me. I don't want ticks 157 00:09:53,800 --> 00:09:57,240 Speaker 1: on my dog. But parasites in general as a topic 158 00:09:57,440 --> 00:10:03,559 Speaker 1: of research is fascinating because of how incredibly specialized they are. 159 00:10:03,800 --> 00:10:08,320 Speaker 1: It's almost beyond belief. In terms of your your questionab well, 160 00:10:08,360 --> 00:10:12,520 Speaker 1: how does their needs for a host and mating interact? 161 00:10:12,520 --> 00:10:16,319 Speaker 1: It does seem counterintuitive, right, like why would you if 162 00:10:16,320 --> 00:10:19,360 Speaker 1: you want to be able to mate, um, you know, 163 00:10:19,559 --> 00:10:23,040 Speaker 1: having to be on another animal to get your food. 164 00:10:23,080 --> 00:10:25,520 Speaker 1: It's like, well, that seems like that would potentially limit 165 00:10:25,520 --> 00:10:28,040 Speaker 1: the dating pool because you're you know, just hopping from 166 00:10:28,040 --> 00:10:30,960 Speaker 1: animal to animal. But they actually don't have too much 167 00:10:31,000 --> 00:10:33,600 Speaker 1: of a problem. So, first of all, there are two 168 00:10:34,000 --> 00:10:38,000 Speaker 1: main types of ticks. There are hard ticks and soft ticks, 169 00:10:38,000 --> 00:10:42,680 Speaker 1: and this encompasses a number of species. Hard ticks will 170 00:10:42,720 --> 00:10:45,680 Speaker 1: actually mate on top of their hosts, which you know, 171 00:10:45,800 --> 00:10:50,160 Speaker 1: well yucky, but the female will gorge herself on blood 172 00:10:50,440 --> 00:10:53,080 Speaker 1: after mating and then drop off to lay her eggs. 173 00:10:53,840 --> 00:10:57,679 Speaker 1: Soft ticks, the other group of species of ticks, don't 174 00:10:57,800 --> 00:11:01,000 Speaker 1: spend as much time on their hosts. They typically just 175 00:11:01,080 --> 00:11:03,440 Speaker 1: kind of bite their hosts, they get a little meal, um, 176 00:11:03,559 --> 00:11:07,800 Speaker 1: so they uh well, actually mate off of their hosts. 177 00:11:07,800 --> 00:11:11,120 Speaker 1: So wherever they are usually like in grasses, and so 178 00:11:11,320 --> 00:11:14,560 Speaker 1: they will feed after mating, so they may feed on 179 00:11:14,600 --> 00:11:18,160 Speaker 1: a host, drop off and then lay her eggs. Uh So, 180 00:11:18,280 --> 00:11:22,000 Speaker 1: in terms of the tick dating pool, unfortunately, there are 181 00:11:22,040 --> 00:11:25,320 Speaker 1: just so many ticks out there, so many ticks in 182 00:11:25,360 --> 00:11:29,360 Speaker 1: the sea, that they don't really have too much of 183 00:11:29,360 --> 00:11:31,720 Speaker 1: a struggle to find a mate even if they are 184 00:11:31,800 --> 00:11:34,440 Speaker 1: hopping on an animal. So if you have a tick 185 00:11:34,559 --> 00:11:38,080 Speaker 1: hopping on a deer, the chances that they encounter another 186 00:11:38,120 --> 00:11:42,240 Speaker 1: deer or another tick on that deer pretty high unfortunately 187 00:11:42,320 --> 00:11:45,800 Speaker 1: for that deer. And if they do struggle to find 188 00:11:45,800 --> 00:11:48,400 Speaker 1: a host to feed on and find a mate, they 189 00:11:48,440 --> 00:11:52,280 Speaker 1: actually have some tricks up there, little ticks sleeves. Soft 190 00:11:52,440 --> 00:11:56,720 Speaker 1: ticks can survive years between feedings if they can't find 191 00:11:56,760 --> 00:11:59,640 Speaker 1: a suitable host, and they go into this kind of 192 00:11:59,679 --> 00:12:04,280 Speaker 1: stay a sis until they detect a host nearby. So yeah, 193 00:12:04,320 --> 00:12:07,880 Speaker 1: they are unfortunately for some of us who don't like 194 00:12:07,960 --> 00:12:10,880 Speaker 1: getting bitten by ticks. They're very good at finding hosts 195 00:12:10,920 --> 00:12:14,240 Speaker 1: and they're very patient, so they will be able to 196 00:12:14,320 --> 00:12:19,600 Speaker 1: find a mate and a host, no problem, all right. 197 00:12:19,679 --> 00:12:23,240 Speaker 1: And this is a short and sweet question from j 198 00:12:24,520 --> 00:12:29,679 Speaker 1: who asks why are possums so perfect? They have little hands? 199 00:12:30,520 --> 00:12:34,120 Speaker 1: Thank you, Ja, Yes, I agree a possums and possums 200 00:12:34,120 --> 00:12:37,960 Speaker 1: are amazing. So oh possums are the ones native to 201 00:12:38,200 --> 00:12:41,640 Speaker 1: the Americas, and we often call them possums if you're 202 00:12:41,679 --> 00:12:48,200 Speaker 1: in really sort of deep in the technical uh possum world. Technically, 203 00:12:48,720 --> 00:12:53,960 Speaker 1: um possum refers to marsupials found in Australia, another a 204 00:12:54,040 --> 00:12:58,040 Speaker 1: very similar but a different species. Oh possums and the 205 00:12:58,080 --> 00:13:01,959 Speaker 1: Americas and possums are both more supials. The possums found 206 00:13:02,000 --> 00:13:06,280 Speaker 1: in Australia are arguably cuter than our opossums, but I 207 00:13:06,320 --> 00:13:09,720 Speaker 1: think that's also kind of subjective, and I love opossums. 208 00:13:09,760 --> 00:13:13,760 Speaker 1: I think they're adorable, so whatever. Um, But opossums, the 209 00:13:14,080 --> 00:13:18,800 Speaker 1: North American impossums are actually the only more supial found 210 00:13:18,840 --> 00:13:23,800 Speaker 1: in North America. They also have opposable thumbs and prehensile 211 00:13:23,920 --> 00:13:27,720 Speaker 1: tails that allow them to grip onto tree branches, so 212 00:13:28,320 --> 00:13:31,760 Speaker 1: very curiously primate like, but they are not primates. They 213 00:13:31,760 --> 00:13:37,320 Speaker 1: are marsupials. Despite looking maybe kind of intimidating or scary, 214 00:13:37,360 --> 00:13:40,760 Speaker 1: they are not at all aggressive. And when they puff 215 00:13:40,840 --> 00:13:43,920 Speaker 1: up it's kind of like a frightened house cat. They're 216 00:13:43,960 --> 00:13:47,160 Speaker 1: just they're just trying to seem like they're big and 217 00:13:47,200 --> 00:13:50,000 Speaker 1: scary and tough, and but really they don't want to 218 00:13:50,040 --> 00:13:52,000 Speaker 1: fight you. That's the last thing that they want to do. 219 00:13:52,320 --> 00:13:57,680 Speaker 1: In fact, they'd rather play dead when they are seriously threatened, 220 00:13:57,760 --> 00:14:00,480 Speaker 1: so they can actually lower their body and picture and 221 00:14:00,600 --> 00:14:03,800 Speaker 1: release a foul smell to make the act very convincing. 222 00:14:04,080 --> 00:14:07,600 Speaker 1: They're the Daniel day Lewis of method acting in terms 223 00:14:07,640 --> 00:14:10,280 Speaker 1: of playing dead. They really don't want to mess with you, 224 00:14:10,520 --> 00:14:13,760 Speaker 1: and they may kind of like surprise you sometimes because 225 00:14:13,800 --> 00:14:16,120 Speaker 1: you're like, go, you're taking your trash out and book, 226 00:14:16,200 --> 00:14:19,760 Speaker 1: there's a possum. But uh, they really don't don't mean 227 00:14:19,800 --> 00:14:23,000 Speaker 1: any harm. And they all that hissing and puffing, that's 228 00:14:23,000 --> 00:14:25,680 Speaker 1: all because they're scared of you. And they're actually great 229 00:14:25,720 --> 00:14:29,160 Speaker 1: to have around in your community because speaking of ticks, 230 00:14:29,200 --> 00:14:32,400 Speaker 1: which we talked about earlier, they love to eat ticks. 231 00:14:32,480 --> 00:14:34,680 Speaker 1: They eat a bunch of ticks. They eat the same 232 00:14:34,760 --> 00:14:37,720 Speaker 1: kinds of ticks that cause lime disease. So hooray for 233 00:14:37,800 --> 00:14:40,600 Speaker 1: possums or a possums, whatever you want to call them. 234 00:14:40,680 --> 00:14:44,080 Speaker 1: I'm not gonna I'm not gonna judge you if you 235 00:14:44,160 --> 00:14:47,280 Speaker 1: call them possums. I think that's totally fine. So yeah, 236 00:14:47,440 --> 00:14:50,760 Speaker 1: I love apossums too. They're adorable, they're sweet, they're they're 237 00:14:50,760 --> 00:14:55,760 Speaker 1: a little trash buddies. And then I got some wonderful questions. 238 00:14:55,800 --> 00:14:58,720 Speaker 1: Actually two questions are very similar. Soul answer them both 239 00:14:58,720 --> 00:15:03,160 Speaker 1: at the same time. How do animals that reproduce parthenogenically 240 00:15:03,680 --> 00:15:08,920 Speaker 1: maintain genetic diversity? Also, since platypus and some ant eaters 241 00:15:09,000 --> 00:15:11,280 Speaker 1: lay eggs, would you try them and this is from 242 00:15:11,280 --> 00:15:17,080 Speaker 1: twenty magic on Twitter. And another question those lizards in 243 00:15:17,120 --> 00:15:20,840 Speaker 1: Arizona where the species and is only female. Does each 244 00:15:20,920 --> 00:15:23,680 Speaker 1: lizard just reproduce a clone of itself or are there 245 00:15:23,760 --> 00:15:27,280 Speaker 1: eggs mixing somehow? If so, can we figure out how 246 00:15:27,320 --> 00:15:29,720 Speaker 1: to do this with human couples? And this is from 247 00:15:29,720 --> 00:15:32,000 Speaker 1: Hannah Michael's I've actually had Halla on my show and 248 00:15:32,040 --> 00:15:34,360 Speaker 1: she's a good friend of mine, So thanks Hannah for 249 00:15:34,520 --> 00:15:37,880 Speaker 1: sitting in your question. I love these questions because I 250 00:15:37,880 --> 00:15:40,800 Speaker 1: get to talk about the whiptail lizard, and I get 251 00:15:40,840 --> 00:15:43,240 Speaker 1: to talk about platypuses and lana treams, and I love 252 00:15:43,280 --> 00:15:46,400 Speaker 1: all these animals. So here we go. First, I'll answer 253 00:15:46,440 --> 00:15:49,720 Speaker 1: the question would I eat a platypus egg? And when 254 00:15:49,760 --> 00:15:52,680 Speaker 1: you say ant eater, I think you are referring to 255 00:15:52,800 --> 00:15:57,720 Speaker 1: the spiny ant eater a k A kidna. Actually, so kidnas, 256 00:15:57,720 --> 00:16:02,280 Speaker 1: just like platypuses, are monotorying, and they actually aren't related 257 00:16:02,320 --> 00:16:04,920 Speaker 1: to other ant eaters like the giant ant eater, but 258 00:16:04,920 --> 00:16:07,120 Speaker 1: they're just called a spiny ant eater because they have 259 00:16:07,280 --> 00:16:11,480 Speaker 1: that long snoot and they do eat ants. So monotreams 260 00:16:11,520 --> 00:16:16,360 Speaker 1: are a fascinating ancient off branch of mammals, and they 261 00:16:16,640 --> 00:16:21,600 Speaker 1: do lay eggs, so they do actually produce milk though, 262 00:16:22,000 --> 00:16:24,840 Speaker 1: but instead of it kind of coming out of nipples 263 00:16:24,880 --> 00:16:27,000 Speaker 1: all nice and tidy like most mammals, are just kind 264 00:16:27,000 --> 00:16:31,800 Speaker 1: of gooches out of their their pores on on their bellies, 265 00:16:32,320 --> 00:16:34,120 Speaker 1: which is a little weird, but you know, hey, you 266 00:16:34,200 --> 00:16:38,280 Speaker 1: do you monotreams. I'm not here to judge, but they 267 00:16:38,520 --> 00:16:42,480 Speaker 1: do lay eggs. However, they do not lay unfertilized eggs 268 00:16:42,520 --> 00:16:45,000 Speaker 1: like chickens, so every egg they lay is actually going 269 00:16:45,040 --> 00:16:47,640 Speaker 1: to be a fertilized egg. So if I was to 270 00:16:47,840 --> 00:16:52,440 Speaker 1: eat a platypus or a kidna egg, I'd be eating 271 00:16:52,560 --> 00:16:57,320 Speaker 1: some platypus or a kidnea embryo or fetus. So no, 272 00:16:57,440 --> 00:17:01,000 Speaker 1: I would probably not not eat one of their eggs. 273 00:17:01,120 --> 00:17:03,840 Speaker 1: I'm not sure i'd like the mouth feel. So now 274 00:17:03,960 --> 00:17:08,320 Speaker 1: onto the question. Both Magic and my friend Hannah asked 275 00:17:08,400 --> 00:17:12,360 Speaker 1: about parthenogenesis. So parthenogenesis is a type of a sexual 276 00:17:12,400 --> 00:17:16,720 Speaker 1: reproduction in which an embryo from an unfertilized egg develops 277 00:17:16,800 --> 00:17:21,400 Speaker 1: to maturity. So it is true that reproducing a sexually 278 00:17:21,560 --> 00:17:26,120 Speaker 1: comes with the problem of limiting genetic diversity. Some species 279 00:17:26,160 --> 00:17:29,120 Speaker 1: avoid this by going through cycles of sexual and then 280 00:17:29,160 --> 00:17:32,640 Speaker 1: a sexual reproductions. So a fids do this. There are 281 00:17:32,680 --> 00:17:37,800 Speaker 1: actually many generations of clonal females with aphids, but then 282 00:17:37,840 --> 00:17:40,280 Speaker 1: when the conditions are right, there is a phase of 283 00:17:40,600 --> 00:17:46,359 Speaker 1: sexual reproduction. So during the parthenogenic phases, the a sexual phases, 284 00:17:46,800 --> 00:17:51,400 Speaker 1: the females only give birth to live female nymphs. Nymphs 285 00:17:51,400 --> 00:17:55,560 Speaker 1: are immature aphids, and in fact those nymphs can be 286 00:17:55,600 --> 00:18:00,480 Speaker 1: borne pregnant already with their own clone. So it's an 287 00:18:00,480 --> 00:18:03,480 Speaker 1: a FIT giving birth to an a fit, which is 288 00:18:03,480 --> 00:18:07,080 Speaker 1: a clone of itself. But that little baby, if it 289 00:18:07,200 --> 00:18:11,840 Speaker 1: is already pregnant with its own clone, which is you know, weird. 290 00:18:11,880 --> 00:18:17,560 Speaker 1: This is called telescopic development. But as you guys pointed out, 291 00:18:17,800 --> 00:18:20,960 Speaker 1: this is a problem because how do you maintain genetic 292 00:18:20,960 --> 00:18:24,720 Speaker 1: diversity in your population. Because when you don't have genetic diversity, 293 00:18:24,760 --> 00:18:27,680 Speaker 1: if you're all clones, as soon as there's a new 294 00:18:27,800 --> 00:18:32,640 Speaker 1: disease or a new predator or parasite or even changing conditions, 295 00:18:33,000 --> 00:18:37,240 Speaker 1: you don't have enough genes to kind of shuffle through 296 00:18:37,800 --> 00:18:42,399 Speaker 1: to get characteristics that may help your species survive during 297 00:18:42,800 --> 00:18:46,800 Speaker 1: these changes, So you'll just kind of go extinct. So 298 00:18:47,080 --> 00:18:49,960 Speaker 1: their solution is to go through these periods of sexual 299 00:18:50,000 --> 00:18:53,560 Speaker 1: reproduction in between the clonal reproduction. So this gives them 300 00:18:53,720 --> 00:18:58,680 Speaker 1: the advantage of clonal reproduction, which is super fast, super smooth, 301 00:18:58,800 --> 00:19:01,720 Speaker 1: like just pumping out many many clones. You know, think 302 00:19:01,760 --> 00:19:04,600 Speaker 1: of Star Wars, an army of clones. But then you 303 00:19:04,800 --> 00:19:08,560 Speaker 1: just like every so often, inject some genetic diversity into 304 00:19:08,600 --> 00:19:11,800 Speaker 1: the population so you don't get this genetic fall neck. 305 00:19:12,040 --> 00:19:15,360 Speaker 1: So during the sexual phase, when weather conditions are right 306 00:19:15,560 --> 00:19:19,359 Speaker 1: and the a fit females will start giving birth to 307 00:19:19,680 --> 00:19:24,600 Speaker 1: parthenogenic females but also males. So typically when they go 308 00:19:24,760 --> 00:19:28,360 Speaker 1: through their a sexual cycles, it's just female clones, a 309 00:19:28,400 --> 00:19:32,199 Speaker 1: real wind for feminism. So but during the sexual phase, 310 00:19:32,280 --> 00:19:35,160 Speaker 1: they give birth to both females and males, and then 311 00:19:35,320 --> 00:19:39,199 Speaker 1: that generation goes on to do sexual reproduction and they 312 00:19:39,240 --> 00:19:42,960 Speaker 1: actually lay eggs instead of giving life birth. So that's 313 00:19:42,960 --> 00:19:45,480 Speaker 1: how they actually kind of have a little loophole that 314 00:19:45,520 --> 00:19:49,040 Speaker 1: allows them to do generations of clonal females. But then 315 00:19:49,040 --> 00:19:50,720 Speaker 1: they mix it up with a little bit of sex 316 00:19:50,800 --> 00:19:54,200 Speaker 1: here and there, so they have some genetic diversity. As 317 00:19:54,320 --> 00:20:00,760 Speaker 1: for the truly all female parthenogenic species, there's one called 318 00:20:00,800 --> 00:20:05,240 Speaker 1: the desert grassland whiptail lizards of New Mexico. So these 319 00:20:05,240 --> 00:20:09,280 Speaker 1: are a lizard that is an all female species. They 320 00:20:09,520 --> 00:20:14,240 Speaker 1: do parthenogenic reproduction. They do not have sex at all. 321 00:20:14,600 --> 00:20:20,199 Speaker 1: They're like you know, Amazonian uh, mythical ladies who just 322 00:20:20,320 --> 00:20:23,760 Speaker 1: are chilling out, all female um. And they actually have 323 00:20:23,840 --> 00:20:27,240 Speaker 1: a really interesting genetic story. So they actually have three 324 00:20:27,240 --> 00:20:30,600 Speaker 1: sets of chromosomes that they got from the initial mutation 325 00:20:30,960 --> 00:20:35,760 Speaker 1: that kind of spawned this all female, parthenogenic species of lizard. 326 00:20:35,960 --> 00:20:40,359 Speaker 1: So instead of the regular two sets of chromosome that humans, 327 00:20:40,640 --> 00:20:43,920 Speaker 1: other mammals, and other diploid sex having animals have, they 328 00:20:43,920 --> 00:20:47,440 Speaker 1: have three sets. And this means that the whiptail lizards 329 00:20:47,480 --> 00:20:51,600 Speaker 1: can effectively shuffle through their deck of genes. They actually 330 00:20:51,720 --> 00:20:56,240 Speaker 1: recombine their own three sets of chromosomes during the process 331 00:20:56,280 --> 00:21:01,680 Speaker 1: of reproduction, allowing them to create non clone parthenogenic offspring. 332 00:21:01,760 --> 00:21:05,960 Speaker 1: So when they give birth without ever having sex, unlike 333 00:21:06,000 --> 00:21:09,000 Speaker 1: the aphids who are giving birth to clones, they're actually 334 00:21:09,000 --> 00:21:12,199 Speaker 1: giving birth to a unique individual who is not a 335 00:21:12,200 --> 00:21:16,240 Speaker 1: clone of themselves, and that is how they bypass that 336 00:21:16,359 --> 00:21:21,119 Speaker 1: problem of genetic bottleneck. Also, fun fact, even though they 337 00:21:21,160 --> 00:21:25,440 Speaker 1: do not have real sex quote unquote, real sex where 338 00:21:25,440 --> 00:21:29,520 Speaker 1: it's uh, you know, where they are exchanging genetic information 339 00:21:29,680 --> 00:21:35,560 Speaker 1: with another of their species. They do pseudocopulations, so they 340 00:21:35,560 --> 00:21:39,200 Speaker 1: will hump each other, essentially, do courtship and mating behaviors 341 00:21:39,200 --> 00:21:43,000 Speaker 1: with each other. This all female species, and that actually 342 00:21:43,000 --> 00:21:45,600 Speaker 1: helps them get in the mood to give birth. So 343 00:21:45,960 --> 00:21:49,200 Speaker 1: even though they're not actually exchanging any genes with their 344 00:21:49,240 --> 00:21:53,200 Speaker 1: fellow members of their species, just the act of this pseudocopulation, 345 00:21:53,680 --> 00:21:56,480 Speaker 1: you know, it helps kind of bring on the hormones 346 00:21:56,600 --> 00:22:01,560 Speaker 1: that will help them give birth to their little Jesus babies, 347 00:22:02,359 --> 00:22:07,159 Speaker 1: all female Jesus lizards. So really interesting stuff. Uh and 348 00:22:07,200 --> 00:22:09,320 Speaker 1: I think it ties back in earlier when we're talking 349 00:22:09,359 --> 00:22:13,480 Speaker 1: about just the incredible diversity of how sex works in nature. 350 00:22:14,000 --> 00:22:16,679 Speaker 1: Uh So if anyone says like, oh, you know, that's unnatural, 351 00:22:16,840 --> 00:22:19,919 Speaker 1: like whatever sex thing, it's like you don't know anything 352 00:22:19,920 --> 00:22:23,439 Speaker 1: about nature. Nature is buck wild. I guess that's the 353 00:22:23,480 --> 00:22:32,040 Speaker 1: definition of nature. Here is a question from Mark f. 354 00:22:32,600 --> 00:22:35,720 Speaker 1: This may be a dumb one, but how do animals 355 00:22:35,720 --> 00:22:38,280 Speaker 1: know to breed with their species? How do the blue 356 00:22:38,320 --> 00:22:40,800 Speaker 1: jays in my neighborhood no to breed with blue jays 357 00:22:40,800 --> 00:22:43,560 Speaker 1: instead of the robin's nearby. This is from Mark f 358 00:22:43,800 --> 00:22:46,840 Speaker 1: It's not at all dumb question. Every time guys that 359 00:22:46,920 --> 00:22:48,960 Speaker 1: you say like, oh, this may be a dumb question, 360 00:22:49,000 --> 00:22:51,840 Speaker 1: it never is, so don't worry about it. This is 361 00:22:51,880 --> 00:22:54,359 Speaker 1: a great question in terms of like being able to 362 00:22:54,400 --> 00:22:57,040 Speaker 1: breed with your own species. For some animals, it's just 363 00:22:57,160 --> 00:23:01,200 Speaker 1: pure instinct that you know, come pre programmed with these 364 00:23:01,240 --> 00:23:04,720 Speaker 1: mating instincts, um. But for some other animals, including many 365 00:23:04,760 --> 00:23:09,560 Speaker 1: species of birds, they actually learn as juveniles based on 366 00:23:09,800 --> 00:23:13,240 Speaker 1: their parents. So this is called imprinting. So they see 367 00:23:13,240 --> 00:23:16,360 Speaker 1: their parents after they hatch and they imprint upon them 368 00:23:16,359 --> 00:23:18,640 Speaker 1: that this is my species, this is who I am. 369 00:23:19,160 --> 00:23:21,760 Speaker 1: And this is actually very important for many species of 370 00:23:21,840 --> 00:23:25,959 Speaker 1: songbirds because this is how they learn their own species 371 00:23:26,040 --> 00:23:29,800 Speaker 1: specific calls, so they're mating calls, their alarm calls. They 372 00:23:29,880 --> 00:23:33,200 Speaker 1: learn from their parents because they imprint. They as soon 373 00:23:33,240 --> 00:23:36,640 Speaker 1: as they start to see the blurry world as little hatchlings, 374 00:23:36,640 --> 00:23:38,520 Speaker 1: they see their parents like this is me, that's who 375 00:23:38,520 --> 00:23:43,640 Speaker 1: I am, um. But sometimes this goes a little bit 376 00:23:44,160 --> 00:23:47,679 Speaker 1: cock eyed, because if birds are raised by another species 377 00:23:47,720 --> 00:23:52,040 Speaker 1: of bird and they imprint upon the wrong species, that's 378 00:23:52,160 --> 00:23:55,720 Speaker 1: they'll just guilelessly think that they are this other species, 379 00:23:56,119 --> 00:23:59,800 Speaker 1: and they will attempt to mate with their adoptive parental species. 380 00:24:00,200 --> 00:24:04,359 Speaker 1: In fact, this is such a problem that when conservationists 381 00:24:04,440 --> 00:24:07,960 Speaker 1: raise baby birds like and trying to repopulate birds and 382 00:24:08,000 --> 00:24:12,639 Speaker 1: these conservation efforts such as sandhill cranes, they have to 383 00:24:12,680 --> 00:24:15,800 Speaker 1: be very careful that the sandhill cranes don't see that 384 00:24:15,840 --> 00:24:18,640 Speaker 1: it's humans taking care of them, otherwise the cranes will 385 00:24:18,680 --> 00:24:21,800 Speaker 1: imprint upon the humans. So in order to feed them, 386 00:24:21,840 --> 00:24:24,560 Speaker 1: what they do is they actually have a hand puppet 387 00:24:25,000 --> 00:24:28,920 Speaker 1: that looks like a sandhill crane to feed the birds, 388 00:24:29,400 --> 00:24:33,240 Speaker 1: so that the baby birds will see the hand puppet 389 00:24:33,280 --> 00:24:35,879 Speaker 1: of the sandhill crane and think, okay, this is what 390 00:24:35,960 --> 00:24:38,960 Speaker 1: I look like, this is my species instead of being 391 00:24:38,960 --> 00:24:42,280 Speaker 1: fed by a humans. So you'll see these researchers like 392 00:24:42,480 --> 00:24:46,639 Speaker 1: ducking under tables just like a Jim Hanson operation, feeding 393 00:24:46,640 --> 00:24:50,359 Speaker 1: these baby sandhill cranes, tricking them into thinking they're being 394 00:24:50,359 --> 00:24:54,600 Speaker 1: fed by sandhill crane so that they understand that's their species, 395 00:24:54,600 --> 00:24:56,880 Speaker 1: so that they can be released into the wild and 396 00:24:57,400 --> 00:25:01,160 Speaker 1: understand their sandhill cranes and mate and uh be able 397 00:25:01,200 --> 00:25:05,879 Speaker 1: to repopulate. So but when you don't do this, a 398 00:25:05,920 --> 00:25:08,119 Speaker 1: bird can imprint on a human and think, oh, this 399 00:25:08,200 --> 00:25:09,919 Speaker 1: is what I look like, I must be a human. 400 00:25:10,080 --> 00:25:12,920 Speaker 1: Sometimes they fall in love with human beings and they 401 00:25:12,960 --> 00:25:16,280 Speaker 1: just think they're they think they're people. Uh. And this 402 00:25:16,359 --> 00:25:20,000 Speaker 1: can happen naturally as well. Uh. There was a Canada 403 00:25:20,080 --> 00:25:24,280 Speaker 1: goose spotted uh. Speaking of sandhill cranes. The Canada goose 404 00:25:24,440 --> 00:25:28,359 Speaker 1: also imprints upon their parents. But this Canada goose was 405 00:25:28,480 --> 00:25:32,679 Speaker 1: adopted by sandhill crane probably some kind of egg mishap, 406 00:25:33,000 --> 00:25:34,879 Speaker 1: and it just thought it was a sandhill crane. So 407 00:25:34,920 --> 00:25:37,280 Speaker 1: I hang out hung out with the sandhill cranes. Uh. 408 00:25:37,800 --> 00:25:40,960 Speaker 1: Thinks this is perfectly normal. The sandhill cranes didn't seem 409 00:25:40,960 --> 00:25:44,080 Speaker 1: to mind it, So yeah, that's what happens, all right. 410 00:25:44,520 --> 00:25:47,680 Speaker 1: And I got a question from another front of the show, 411 00:25:47,760 --> 00:25:52,560 Speaker 1: Alex Schmidt, host of Secretly Incredibly Fascinating, and I've had 412 00:25:52,600 --> 00:25:54,399 Speaker 1: him on the show and he's a great guy. Highly 413 00:25:54,400 --> 00:25:57,960 Speaker 1: recommend his podcast. And he writes, what's an exciting thing 414 00:25:58,000 --> 00:26:03,800 Speaker 1: worth knowing about woodchucks? And also someone responded to this 415 00:26:03,920 --> 00:26:08,160 Speaker 1: question saying are they related to nun chucks? Uh? Well, 416 00:26:08,200 --> 00:26:10,800 Speaker 1: thank you for the question, Alex, uh, and thank you 417 00:26:10,840 --> 00:26:15,320 Speaker 1: for the nunchuck comment. Alberton Um, no, they're not related 418 00:26:15,359 --> 00:26:19,000 Speaker 1: to nunchucks. Be serious. Come on, this is a serious 419 00:26:19,080 --> 00:26:24,840 Speaker 1: science show and jokes will not be tolerated anyways. Wood chucks. 420 00:26:24,880 --> 00:26:27,359 Speaker 1: So what is a woodchuck? Does it chuck wood? No? 421 00:26:27,760 --> 00:26:29,800 Speaker 1: Why is it called the woodchuck? Well, I think we 422 00:26:29,880 --> 00:26:33,080 Speaker 1: talked about this a while back on the show, but uh, 423 00:26:33,240 --> 00:26:38,400 Speaker 1: the likely story is that Colonizer's came here they misunderstood 424 00:26:38,600 --> 00:26:43,600 Speaker 1: the language of the Algonquian Native American Indian nation of 425 00:26:43,800 --> 00:26:47,240 Speaker 1: Rhode Island, and so then they thought like, oh, it 426 00:26:47,240 --> 00:26:51,959 Speaker 1: sounds like woodchuck, which was probably misunderstanding because their actual 427 00:26:52,000 --> 00:26:56,600 Speaker 1: word for ground hogs is okuk chewan. Or it could 428 00:26:56,600 --> 00:27:00,159 Speaker 1: have been that the colonists thought that they were talking 429 00:27:00,160 --> 00:27:04,160 Speaker 1: about a woodchuck, whereas they have a word that sounds 430 00:27:04,240 --> 00:27:07,399 Speaker 1: kind of like woodchuck, but that's actually word for a 431 00:27:07,440 --> 00:27:12,000 Speaker 1: weasel like animal called a fisher. So you know, the 432 00:27:12,119 --> 00:27:16,439 Speaker 1: name woodchuck is just based on stupidity. But here we 433 00:27:16,520 --> 00:27:19,760 Speaker 1: are we call them woodchucks, then we have tongue twisters. 434 00:27:19,760 --> 00:27:24,679 Speaker 1: But really, hey, woodchucks are just groundhogs, so you know, 435 00:27:25,040 --> 00:27:28,760 Speaker 1: just groundhogs by another name. In fact, they have other 436 00:27:28,920 --> 00:27:32,800 Speaker 1: names such as whistle pig due to the noises they make, 437 00:27:33,240 --> 00:27:36,760 Speaker 1: or mouse bear because I guess they look like tiny bears. 438 00:27:36,920 --> 00:27:39,199 Speaker 1: I'm not sure I buy it, but hey, you know 439 00:27:39,440 --> 00:27:42,720 Speaker 1: I guess I'm I wasn't there when they named these things, 440 00:27:42,760 --> 00:27:47,840 Speaker 1: Otherwise I probably would have named them little little fluff buddies. 441 00:27:48,160 --> 00:27:50,000 Speaker 1: And this is why they don't put me in charge 442 00:27:50,000 --> 00:27:53,760 Speaker 1: of name and animals. So groundhogs a K wood chucks 443 00:27:53,760 --> 00:27:56,600 Speaker 1: a K whistle pigs a K. Mouse bears are a 444 00:27:56,680 --> 00:28:00,080 Speaker 1: type of large rodent. They are healthy little dudes a 445 00:28:00,160 --> 00:28:04,000 Speaker 1: weigh about thirteen pounds or six kis. Are actually about 446 00:28:04,080 --> 00:28:07,640 Speaker 1: the same size and weight of my dog Cookie, So 447 00:28:07,920 --> 00:28:10,199 Speaker 1: you know, she probably wishes she could take on one 448 00:28:10,240 --> 00:28:12,280 Speaker 1: of these woodchucks, but I don't think so. I don't 449 00:28:12,280 --> 00:28:15,879 Speaker 1: think so, Cookie. Uh. So, they're found all over North 450 00:28:15,920 --> 00:28:20,880 Speaker 1: America and they are burrowing animals who, actually, like bears, 451 00:28:21,040 --> 00:28:24,240 Speaker 1: do hibernate during the winter months. In fact, they are 452 00:28:24,520 --> 00:28:30,159 Speaker 1: really true hibernators, more so than bears. Bears don't really 453 00:28:30,280 --> 00:28:33,000 Speaker 1: hibernate in the true sense of the word. They go 454 00:28:33,240 --> 00:28:37,199 Speaker 1: into a lighter state of torpor, like a really, really 455 00:28:37,359 --> 00:28:40,880 Speaker 1: deep sleep. They do slow down their metallobolism, but they 456 00:28:40,960 --> 00:28:44,800 Speaker 1: can wake up, so during torpor, they will wake up 457 00:28:44,840 --> 00:28:49,120 Speaker 1: relatively quickly in response to danger. But hibernation is a 458 00:28:49,200 --> 00:28:53,120 Speaker 1: much more serious version of this. It's more like suspended animation, 459 00:28:53,520 --> 00:28:56,800 Speaker 1: and the groundhog is almost completely dead to the world. 460 00:28:57,160 --> 00:29:02,240 Speaker 1: During hibernation, groundhogs body temperature or drops from nine degrees fahrenheit, 461 00:29:02,240 --> 00:29:06,040 Speaker 1: which is about the normal human temperature, maybe a little higher, 462 00:29:06,240 --> 00:29:10,400 Speaker 1: but it drops to thirty seven degrees fahrenheit, which we 463 00:29:10,440 --> 00:29:13,880 Speaker 1: would be so extremely dead at this point, like anything 464 00:29:14,320 --> 00:29:18,200 Speaker 1: around seventy degrees were already probably going to be dead. Uh, 465 00:29:18,240 --> 00:29:21,520 Speaker 1: thirty seven degrees, we've probably been dead for a while. 466 00:29:21,680 --> 00:29:25,960 Speaker 1: That's yeah. No. Also, the groundhogs breathing slows to two 467 00:29:26,120 --> 00:29:30,160 Speaker 1: breaths a minute and their heart beats slows to five 468 00:29:30,400 --> 00:29:34,800 Speaker 1: beats per minutes, so like about as dead as they 469 00:29:34,840 --> 00:29:39,479 Speaker 1: can be without actually being dead. For the entire period 470 00:29:39,480 --> 00:29:43,320 Speaker 1: of hibernation, which can last around a hundred and fifty days, 471 00:29:43,360 --> 00:29:46,640 Speaker 1: they will not eat and they lose about a fourth 472 00:29:46,720 --> 00:29:50,600 Speaker 1: of their body weight. So it's able to survive this 473 00:29:50,680 --> 00:29:56,560 Speaker 1: extreme food deprivation because their metabolism have has been slowed 474 00:29:56,640 --> 00:30:00,320 Speaker 1: to an absolute crawl. So it's essentially into this beended 475 00:30:00,320 --> 00:30:04,600 Speaker 1: animation other quick which check facts. They are able to 476 00:30:04,640 --> 00:30:08,680 Speaker 1: grind up tough vegetation like wild grasses because their teeth 477 00:30:08,800 --> 00:30:13,200 Speaker 1: grow constantly to withstand the grinding. In fact, they grow 478 00:30:13,240 --> 00:30:15,880 Speaker 1: around a sixteenth of an inch or one point five 479 00:30:15,920 --> 00:30:19,720 Speaker 1: millimeters every week. If their teeth are not aligned properly 480 00:30:19,840 --> 00:30:22,400 Speaker 1: and they are not chewed down by the act of 481 00:30:22,480 --> 00:30:27,600 Speaker 1: munching on grasses, the teeth continually grow until they are tusks, 482 00:30:27,680 --> 00:30:30,800 Speaker 1: and they can actually be lethal if they grow up 483 00:30:30,840 --> 00:30:34,200 Speaker 1: into the groundhogs jaw or grow so wonky and curly 484 00:30:34,280 --> 00:30:38,600 Speaker 1: that they can't chew on grass. So ground hogs are 485 00:30:38,640 --> 00:30:41,960 Speaker 1: actually quite social and friendly with each other. They dig 486 00:30:42,000 --> 00:30:46,000 Speaker 1: burrows together, they whistle to report threats to each other. 487 00:30:46,720 --> 00:30:49,400 Speaker 1: And if you think that groundhogs look a little bit 488 00:30:49,440 --> 00:30:52,520 Speaker 1: like marmots, you are correct. They are actually a type 489 00:30:52,520 --> 00:30:56,680 Speaker 1: of marmot. And by the way, marmots are actually technically 490 00:30:56,680 --> 00:31:01,240 Speaker 1: a type of ground squirrel, So yeah, other species of 491 00:31:01,280 --> 00:31:04,880 Speaker 1: marmots and ground squirrels are also pretty social. They have 492 00:31:05,000 --> 00:31:09,160 Speaker 1: these like little colonies where they dig burrows and they 493 00:31:09,160 --> 00:31:12,840 Speaker 1: will alert each other two threats. So, uh, you know, 494 00:31:12,880 --> 00:31:15,600 Speaker 1: this is what we got from wood chucks to basically 495 00:31:15,600 --> 00:31:19,360 Speaker 1: ground squirrels. This is a quite a reveal fun fact 496 00:31:19,400 --> 00:31:22,800 Speaker 1: about marmots if you go hiking in the Sequoias. In 497 00:31:22,840 --> 00:31:25,880 Speaker 1: addition to making sure none of your food is left out, 498 00:31:25,920 --> 00:31:28,400 Speaker 1: you also need to be careful about anything you have 499 00:31:28,840 --> 00:31:32,200 Speaker 1: that has your human sweat on it, because marmots love 500 00:31:32,280 --> 00:31:34,840 Speaker 1: the salty taste of human sweat, and we'll try to 501 00:31:34,880 --> 00:31:38,680 Speaker 1: steal your socks, even your hiking poles, which I learned 502 00:31:38,720 --> 00:31:42,520 Speaker 1: when I was hiking with my brother. Uh, a marmot 503 00:31:42,520 --> 00:31:45,360 Speaker 1: grabbed his pole and ran as fast as it could, 504 00:31:45,520 --> 00:31:48,400 Speaker 1: so if the pole hadn't gotten caught on a rock, 505 00:31:48,680 --> 00:31:51,400 Speaker 1: probably the marmot would have my brother's hiking pole to 506 00:31:51,480 --> 00:31:54,880 Speaker 1: this day. So yeah, they love the taste of human sweat, 507 00:31:54,960 --> 00:31:58,360 Speaker 1: which I think is a little alarming because if they 508 00:31:58,440 --> 00:32:00,920 Speaker 1: figure out they can make us it by making us 509 00:32:00,960 --> 00:32:04,040 Speaker 1: really scared, we would probably be in some kind of 510 00:32:04,120 --> 00:32:08,120 Speaker 1: marmot fear factory saw type situation. But luckily they probably 511 00:32:08,120 --> 00:32:11,400 Speaker 1: don't listen to this podcast, so hey, maybe we'll be 512 00:32:11,480 --> 00:32:15,320 Speaker 1: safe from the marmot threat another year. So to end 513 00:32:15,400 --> 00:32:19,000 Speaker 1: the episode, I think I'll play you some lovely groundhog 514 00:32:19,200 --> 00:32:23,080 Speaker 1: slash wood chuck slash whistle pig sounds, so you will 515 00:32:23,120 --> 00:32:29,800 Speaker 1: see why they are also called whistle pigs.
