1
00:00:00,280 --> 00:00:02,920
Speaker 1: Brought to you by the reinvented two thousand twelve Camray.

2
00:00:03,160 --> 00:00:07,560
Speaker 1: It's ready. Are you welcome to Stuff you should Know

3
00:00:08,119 --> 00:00:16,400
Speaker 1: from house Stuff Works dot com? Hey, and welcome to

4
00:00:16,440 --> 00:00:19,600
Speaker 1: the podcast. I'm Josh Clark with me as always is

5
00:00:19,720 --> 00:00:24,800
Speaker 1: Charles W. Chuck Bryant. I am here, sir, and that

6
00:00:24,840 --> 00:00:29,760
Speaker 1: makes this stuff you should know. Indeed, the Friday versions

7
00:00:29,760 --> 00:00:32,600
Speaker 1: been while on the Friday, it is Friday, isn't it?

8
00:00:32,600 --> 00:00:35,200
Speaker 1: Are we shouting out to Kiva? First thing? I think

9
00:00:35,200 --> 00:00:38,720
Speaker 1: we definitely should, dudes and do debts. We have surpassed

10
00:00:39,120 --> 00:00:43,160
Speaker 1: half a million bucks as a team in micro loans

11
00:00:43,760 --> 00:00:46,479
Speaker 1: to Kiva dot org. And that was our goal was

12
00:00:46,520 --> 00:00:48,879
Speaker 1: to hit it in May, and darn it all if

13
00:00:48,920 --> 00:00:51,879
Speaker 1: we didn't do it. We totally did it, and we

14
00:00:51,920 --> 00:01:01,360
Speaker 1: started our team October ten, two nine, and but by

15
00:01:01,400 --> 00:01:05,240
Speaker 1: the next October we'd already passed our two fifty dollar goal,

16
00:01:06,000 --> 00:01:08,120
Speaker 1: and then we wanted to get to five hundred thousand

17
00:01:08,120 --> 00:01:10,800
Speaker 1: in May. I didn't think it was possible. We totally did.

18
00:01:11,000 --> 00:01:14,360
Speaker 1: It's possible because of people like Glenn and Sonja who

19
00:01:14,920 --> 00:01:17,960
Speaker 1: helm the team for us. There are de facto captains.

20
00:01:18,080 --> 00:01:21,479
Speaker 1: It's because of people like Blake this guy who came

21
00:01:21,520 --> 00:01:26,280
Speaker 1: in and UM basically put sixteen lemons I think on

22
00:01:26,480 --> 00:01:28,560
Speaker 1: his credit card because he said he was sick of

23
00:01:28,640 --> 00:01:31,000
Speaker 1: us being so close to half a million dollars but

24
00:01:31,080 --> 00:01:35,200
Speaker 1: not quite there. Um. And everybody who's a member on

25
00:01:35,280 --> 00:01:39,520
Speaker 1: our team who's contributed anything, well at least five bucks. Yeah,

26
00:01:39,560 --> 00:01:42,440
Speaker 1: we're number three on all of Cuba in the number

27
00:01:42,520 --> 00:01:46,600
Speaker 1: of team members, ahead of Team Obama in Australia and Europe.

28
00:01:46,640 --> 00:01:49,280
Speaker 1: We're just so proud of you. We're very proud of everybody,

29
00:01:49,280 --> 00:01:51,360
Speaker 1: and it's just cool. And I guess Glenn and Sonia

30
00:01:51,400 --> 00:01:53,880
Speaker 1: will probably help us figure out the next goal, which

31
00:01:54,160 --> 00:01:56,760
Speaker 1: I guess will be a million bucks. I would say

32
00:01:57,040 --> 00:02:00,040
Speaker 1: we I'd say a million why not, let's do it.

33
00:02:00,120 --> 00:02:02,480
Speaker 1: Might take a year from now, but I ain't going anywhere.

34
00:02:02,520 --> 00:02:05,280
Speaker 1: We'll find out. Let's do it, okay, So our goal

35
00:02:05,360 --> 00:02:09,079
Speaker 1: now is to lend a million dollars on Cuba through

36
00:02:09,080 --> 00:02:11,720
Speaker 1: our stuff. You should know team Let's go, guys, all right,

37
00:02:11,919 --> 00:02:15,400
Speaker 1: way to go. Everybody eat a cupcake, that's right, a

38
00:02:15,520 --> 00:02:17,840
Speaker 1: good one too. And if you want to know about

39
00:02:17,880 --> 00:02:19,880
Speaker 1: CIVA and you don't know about our team, you can

40
00:02:19,919 --> 00:02:23,360
Speaker 1: find that at k I D A dot org slash

41
00:02:23,400 --> 00:02:28,040
Speaker 1: team or is it teams team team slash stuff. You

42
00:02:28,080 --> 00:02:30,280
Speaker 1: should know you can join up at the team and

43
00:02:30,520 --> 00:02:33,519
Speaker 1: just make one little lousy loan and you can get

44
00:02:33,520 --> 00:02:34,960
Speaker 1: your money back and then you can pull it out

45
00:02:35,000 --> 00:02:37,200
Speaker 1: if you want, but you're probably gonna want to reinvest it,

46
00:02:37,200 --> 00:02:39,240
Speaker 1: which is kind of cool. And you know what before

47
00:02:39,240 --> 00:02:41,800
Speaker 1: you do, before you sign up um, or if you

48
00:02:41,960 --> 00:02:44,360
Speaker 1: just recently signed up, you should read our two part

49
00:02:44,400 --> 00:02:47,760
Speaker 1: blog post on CIVA and how we feel about Cuba

50
00:02:48,080 --> 00:02:51,360
Speaker 1: because it's not a perfect system. Um and after a

51
00:02:51,360 --> 00:02:54,480
Speaker 1: while everyone inevitably runs up against the flaws and it

52
00:02:54,520 --> 00:02:57,160
Speaker 1: and talks about quitting and all that and um, so

53
00:02:57,200 --> 00:02:59,280
Speaker 1: we wrote a couple of posts on it so you

54
00:02:59,320 --> 00:03:01,959
Speaker 1: could sort whis why we land at s Y s

55
00:03:02,040 --> 00:03:05,520
Speaker 1: k um and uh, that will bring it up on

56
00:03:05,560 --> 00:03:08,240
Speaker 1: the blogs, right yeah, And just you know, what I've

57
00:03:08,280 --> 00:03:12,240
Speaker 1: learned is just like regular loans, micro loans are no different.

58
00:03:12,320 --> 00:03:15,080
Speaker 1: There are people that get in trouble and should not

59
00:03:15,120 --> 00:03:17,520
Speaker 1: have borrowed what they borrowed. And it's even sadder I

60
00:03:17,560 --> 00:03:20,440
Speaker 1: think that people borrow you know, six hundred bucks and

61
00:03:20,480 --> 00:03:23,600
Speaker 1: can't for that, and so there are there are some downsides,

62
00:03:23,639 --> 00:03:25,640
Speaker 1: but we found not only that there are also tons

63
00:03:25,680 --> 00:03:29,520
Speaker 1: of predators out there lending to people at horrible rates.

64
00:03:29,639 --> 00:03:31,240
Speaker 1: But we believe in Kiva and we found that there

65
00:03:31,240 --> 00:03:35,040
Speaker 1: are many, many more positive associations. So agreed, Moving on,

66
00:03:35,200 --> 00:03:38,920
Speaker 1: Moving on, dude, um So also probably wouldn't hurt to

67
00:03:38,920 --> 00:03:41,560
Speaker 1: go listen to our micro Lending How micro Lending Works

68
00:03:41,600 --> 00:03:45,800
Speaker 1: podcasts where we first discovered Cuba. That's right, um So, Chuck,

69
00:03:45,840 --> 00:03:48,280
Speaker 1: We're going to talk about something that has absolutely nothing

70
00:03:48,320 --> 00:03:51,400
Speaker 1: to do with CIVA as far as I know. Okay,

71
00:03:52,280 --> 00:03:57,119
Speaker 1: I think you're right. Um let's talk first about Australia. Uh,

72
00:03:57,200 --> 00:04:02,520
Speaker 1: Australia is this awesome little all natural laboratory, a giant

73
00:04:02,560 --> 00:04:06,200
Speaker 1: Petrie dish if you will. Just from childhood, I've always

74
00:04:06,200 --> 00:04:09,080
Speaker 1: been amazed that it's a country and a continent. My

75
00:04:09,120 --> 00:04:11,720
Speaker 1: hats always gone off to Australia. So to all of

76
00:04:11,720 --> 00:04:16,440
Speaker 1: our peeps down in Australia, Chuck, take off your hand. Okay,

77
00:04:16,440 --> 00:04:18,920
Speaker 1: there you get You're supposed to say, ohit oit oi, yes,

78
00:04:19,520 --> 00:04:23,400
Speaker 1: just pretend I just did. Um and Uh. The reason

79
00:04:23,440 --> 00:04:26,760
Speaker 1: being is because at one point the the continents all

80
00:04:26,800 --> 00:04:30,520
Speaker 1: formed a super continent, Pangaea, some of the other continents.

81
00:04:30,680 --> 00:04:33,280
Speaker 1: Um kind of stuck together a little more. Australia went

82
00:04:33,320 --> 00:04:36,279
Speaker 1: off by itself, as Australians do. It went off to

83
00:04:36,279 --> 00:04:39,320
Speaker 1: do its own thing, that's right. And um, there were

84
00:04:39,360 --> 00:04:42,640
Speaker 1: animals in existence about sixty million years ago when it

85
00:04:42,680 --> 00:04:47,279
Speaker 1: broke off. Um that we're living on Australia. Yeah. I

86
00:04:47,279 --> 00:04:50,360
Speaker 1: pictured the little crack forming and then separating and literally

87
00:04:50,400 --> 00:04:55,039
Speaker 1: animals looking at their little species brethren going by. That's

88
00:04:55,080 --> 00:04:57,279
Speaker 1: a that's a really good way to look at it too,

89
00:04:57,279 --> 00:05:00,520
Speaker 1: because it's not like these cracks happened like you know

90
00:05:00,760 --> 00:05:03,440
Speaker 1: this this species lives over here and this species lives

91
00:05:03,480 --> 00:05:06,200
Speaker 1: over there, right, I mean that's pretty much exactly how

92
00:05:06,200 --> 00:05:09,360
Speaker 1: it happened. I mean not that quickly, maybe using time

93
00:05:09,360 --> 00:05:16,000
Speaker 1: and last photography, but um, essentially that gave that gave

94
00:05:16,120 --> 00:05:22,120
Speaker 1: rise to related species evolving in in completely different parts

95
00:05:22,120 --> 00:05:24,800
Speaker 1: of the world, that's right. So Australia gave us some

96
00:05:24,839 --> 00:05:31,320
Speaker 1: freak shows like koala, bears, kangaroos, wombats, Tasmanian devils that

97
00:05:31,360 --> 00:05:33,479
Speaker 1: are really different than other animals and other parts of

98
00:05:33,480 --> 00:05:37,000
Speaker 1: the world exactly. Um, but it also gave us a

99
00:05:37,040 --> 00:05:42,159
Speaker 1: little something called the flying falangists. I've never heard of this, Okay,

100
00:05:42,200 --> 00:05:45,760
Speaker 1: the flying falangists looks it's a it's a rodent, has

101
00:05:45,760 --> 00:05:48,800
Speaker 1: a tail that has a tiny head just covered in fur.

102
00:05:49,600 --> 00:05:52,760
Speaker 1: It'll give you some sort of pestilent disease if you

103
00:05:52,800 --> 00:05:57,000
Speaker 1: eat it raw. Yeah. Um. But it also has this

104
00:05:57,279 --> 00:06:02,760
Speaker 1: weird little um bit of in that were tracks, except

105
00:06:02,760 --> 00:06:06,120
Speaker 1: when it's jumping from tree to tree, it spreads its

106
00:06:06,240 --> 00:06:09,480
Speaker 1: arms and legs out yep, spread eagle, and this flap

107
00:06:09,520 --> 00:06:13,640
Speaker 1: of skin in between its arm and say it's ribs

108
00:06:14,360 --> 00:06:18,960
Speaker 1: and then its legs and it's so say buttocks. This

109
00:06:19,320 --> 00:06:22,640
Speaker 1: skin flaps out to allow it to glide. It's like

110
00:06:23,000 --> 00:06:25,600
Speaker 1: it's like those flying dudes that you see now, the

111
00:06:25,640 --> 00:06:29,760
Speaker 1: skydivers that they basically wear a little flying suits. Yeah,

112
00:06:29,800 --> 00:06:32,480
Speaker 1: wingsuit yeah, wings Those things are awesome. It's pretty cool,

113
00:06:32,880 --> 00:06:35,960
Speaker 1: um and way dangerous. So this is like the original.

114
00:06:36,080 --> 00:06:37,720
Speaker 1: This is the o G of that. Yeah. I think

115
00:06:37,760 --> 00:06:40,480
Speaker 1: it was based on that flying flanges. It sounds like, again,

116
00:06:40,560 --> 00:06:43,800
Speaker 1: a total freak show until you remember, oh yeah, North

117
00:06:43,839 --> 00:06:46,800
Speaker 1: America has flying squirrels that are the exact same thing.

118
00:06:47,000 --> 00:06:48,560
Speaker 1: And I had a pet one. I think I mentioned

119
00:06:48,560 --> 00:06:52,120
Speaker 1: that before you did, didn't you. Okay, So if you

120
00:06:52,200 --> 00:06:54,400
Speaker 1: go back far enough on the family tree, you're going

121
00:06:54,480 --> 00:06:57,640
Speaker 1: to find that both of these animals ancestors were living

122
00:06:57,760 --> 00:07:01,119
Speaker 1: on Australia and elsewhere in the world at the time.

123
00:07:01,200 --> 00:07:04,600
Speaker 1: That's right. Okay, so when they when they split off,

124
00:07:04,640 --> 00:07:09,480
Speaker 1: when Australia broke off, um, this this animal's habitat was disrupted,

125
00:07:09,720 --> 00:07:12,000
Speaker 1: and so you had two members of the same species

126
00:07:12,000 --> 00:07:16,800
Speaker 1: living on different parts of the world but evolving completely differently. Right.

127
00:07:17,200 --> 00:07:19,520
Speaker 1: So they've gotten to the point now where the flying

128
00:07:19,560 --> 00:07:22,200
Speaker 1: squirrel and the flying flanges they're not the same animal.

129
00:07:22,640 --> 00:07:27,040
Speaker 1: They're different species because they can't engage in successful reproduction

130
00:07:27,080 --> 00:07:32,560
Speaker 1: any longer. But they still both evolved independently these flaps,

131
00:07:32,880 --> 00:07:37,120
Speaker 1: which are just totally odd. That's what's called parallel evolution, right,

132
00:07:37,160 --> 00:07:40,920
Speaker 1: That's right. And um, the flying flanges and flying squirrel

133
00:07:40,960 --> 00:07:44,360
Speaker 1: are far from the only species that are no longer related,

134
00:07:44,720 --> 00:07:48,280
Speaker 1: that are no longer the same species that have evolved similarly,

135
00:07:48,520 --> 00:07:52,600
Speaker 1: which poses a really big question for biology and evolution.

136
00:07:53,040 --> 00:07:56,920
Speaker 1: How is this happening? It's right. Well, parallel evolution um.

137
00:07:57,280 --> 00:08:00,280
Speaker 1: Further defined is when they're related species that have been split.

138
00:08:01,200 --> 00:08:05,120
Speaker 1: When two different species share these traits, it's morphological similarity

139
00:08:06,000 --> 00:08:09,520
Speaker 1: kind of neat, huh. And when two completely unrelated species

140
00:08:09,560 --> 00:08:15,120
Speaker 1: develop this morphological similarity. It's called convergent evolution. And it's

141
00:08:15,160 --> 00:08:17,080
Speaker 1: kind of hard to tell because we don't know exactly

142
00:08:17,160 --> 00:08:20,960
Speaker 1: how things were millions of years ago. When sure exactly

143
00:08:20,960 --> 00:08:23,720
Speaker 1: which one of these uh we're similar back then? But

144
00:08:23,840 --> 00:08:25,360
Speaker 1: we do know in like the case of the squirrel

145
00:08:25,400 --> 00:08:31,480
Speaker 1: in the Philanger Philanger, Yeah plane filangists, Philanger, I've been

146
00:08:31,520 --> 00:08:35,599
Speaker 1: saying philangists, Philanger. Yeah, it's a Philanger, the flying Philanger.

147
00:08:35,880 --> 00:08:40,720
Speaker 1: What they should is called a squirrel. M. Well, that

148
00:08:40,720 --> 00:08:43,120
Speaker 1: that that occurred to me. Maybe maybe there isn't such

149
00:08:43,120 --> 00:08:45,360
Speaker 1: a thing as parallel evolution. Maybe it's all humans. We're

150
00:08:45,400 --> 00:08:49,200
Speaker 1: just not calling everything the same thing. It's our naming convention.

151
00:08:49,280 --> 00:08:52,839
Speaker 1: There's problem solved. So one of the reason and it's

152
00:08:52,840 --> 00:08:55,000
Speaker 1: pretty simple actually, and it makes a lot of sense

153
00:08:55,040 --> 00:08:58,600
Speaker 1: that parallel evolution can occur is that, um, when you

154
00:08:58,640 --> 00:09:03,360
Speaker 1: have a similar environment with two species, uh, population pressure

155
00:09:03,440 --> 00:09:07,000
Speaker 1: is gonna lead to similar traits, Like we gotta survive,

156
00:09:07,280 --> 00:09:10,480
Speaker 1: So if we live in a similar environment, then we're

157
00:09:10,520 --> 00:09:13,640
Speaker 1: probably gonna evolve similarly. Like if it's really cold, we're

158
00:09:13,679 --> 00:09:18,040
Speaker 1: probably gonna have thick fur as you know, different species. Um,

159
00:09:18,040 --> 00:09:21,160
Speaker 1: it's pretty basic. Another really good example I think that

160
00:09:21,240 --> 00:09:25,679
Speaker 1: was used with teeth, Yes right, yeah, I know that

161
00:09:25,679 --> 00:09:28,040
Speaker 1: it's jumping around a little bit, but that's all right.

162
00:09:28,520 --> 00:09:31,880
Speaker 1: Teeth things we take for granted, they're so ubiquitous. Sharp teeth.

163
00:09:31,880 --> 00:09:34,520
Speaker 1: Sharp teeth are found in all carnivores. And the reason

164
00:09:34,559 --> 00:09:37,880
Speaker 1: why is because it's a really good trait. Yeah right,

165
00:09:38,120 --> 00:09:41,480
Speaker 1: because we can dig into meat. Same thing though, although

166
00:09:41,480 --> 00:09:45,360
Speaker 1: I can't with my stupid bum tooth. I'm I'm devolving

167
00:09:45,480 --> 00:09:49,319
Speaker 1: someday again through technology, I hope. So. So, what you're

168
00:09:49,320 --> 00:09:53,199
Speaker 1: talking about, Chuck is Um with natural selection is that basically,

169
00:09:53,480 --> 00:09:57,480
Speaker 1: if you imagine dropping an animal into a an environment,

170
00:09:57,880 --> 00:10:01,480
Speaker 1: so a jungle, right, there are parts of it that

171
00:10:01,559 --> 00:10:04,560
Speaker 1: are going to allow it to thrive. There are things

172
00:10:04,600 --> 00:10:07,720
Speaker 1: that are going to make it less likely to thrive.

173
00:10:08,760 --> 00:10:11,479
Speaker 1: The things that make it likelier to thrive, or the

174
00:10:11,160 --> 00:10:13,480
Speaker 1: the traits that are going to get passed along from

175
00:10:13,480 --> 00:10:17,120
Speaker 1: generation to generation. As long as they hang along, hang

176
00:10:17,120 --> 00:10:20,280
Speaker 1: on long enough to to survive through the reproduction process,

177
00:10:20,320 --> 00:10:22,920
Speaker 1: then it gets ingrained and boom, you've got yourself a

178
00:10:22,960 --> 00:10:27,640
Speaker 1: trade well by nature, the the traits that allow it

179
00:10:27,679 --> 00:10:31,040
Speaker 1: to hang on long enough to reproduce are going to

180
00:10:31,200 --> 00:10:35,760
Speaker 1: be most successful traits because with reproduction, those are the

181
00:10:35,800 --> 00:10:38,600
Speaker 1: ones that are going to get passed around the most frequently,

182
00:10:38,880 --> 00:10:42,319
Speaker 1: and then eventually the one the animals that had more

183
00:10:42,360 --> 00:10:44,800
Speaker 1: of the traits that didn't allow it to thrive are

184
00:10:44,800 --> 00:10:47,280
Speaker 1: gonna die out. They're not going to reproduce. So on

185
00:10:47,320 --> 00:10:50,240
Speaker 1: a long enough time scale, this reproduction will lead to

186
00:10:50,800 --> 00:10:55,840
Speaker 1: um higher frequency of traits that make an animal fit

187
00:10:56,440 --> 00:10:59,280
Speaker 1: for its environment. Right, Like the guerrilla, for instance, used

188
00:10:59,320 --> 00:11:01,000
Speaker 1: to have a large ale with a pin wheel on

189
00:11:01,000 --> 00:11:03,760
Speaker 1: the end of it, but it was really you know,

190
00:11:03,800 --> 00:11:05,880
Speaker 1: I didn't really do much for him, so over time

191
00:11:05,880 --> 00:11:08,640
Speaker 1: it just kind of went away. Right. That's not true, though,

192
00:11:08,840 --> 00:11:11,480
Speaker 1: is it? No, it's not true. What do you mean?

193
00:11:11,600 --> 00:11:14,080
Speaker 1: Is it all right? It was making sure? Um? So

194
00:11:14,400 --> 00:11:17,440
Speaker 1: these changes though, these traits, right, they just kind of

195
00:11:17,440 --> 00:11:20,880
Speaker 1: seemed to pop up here there, if you're in our

196
00:11:20,920 --> 00:11:25,640
Speaker 1: current understanding of genetics, same nineteen eighties understanding of genetics,

197
00:11:25,800 --> 00:11:28,920
Speaker 1: they just kind of pop up out of nowhere. Um.

198
00:11:29,040 --> 00:11:31,920
Speaker 1: But chuck, if I may digress for a second, please,

199
00:11:32,000 --> 00:11:34,200
Speaker 1: have we ever explained what came first the chicken or

200
00:11:34,240 --> 00:11:38,079
Speaker 1: the egg. Yeah, it's been a while though it has,

201
00:11:38,240 --> 00:11:40,040
Speaker 1: but we have already yeah, but it's been a while.

202
00:11:40,120 --> 00:11:42,560
Speaker 1: I think it deserves a recap okay, because you actually

203
00:11:42,559 --> 00:11:46,440
Speaker 1: know the answer, Yes, I do. I can say that

204
00:11:46,840 --> 00:11:51,760
Speaker 1: the egg came first because the genetic mutation that gives

205
00:11:51,880 --> 00:11:56,160
Speaker 1: rise to new species, to new animals occurs UH in

206
00:11:56,200 --> 00:12:00,800
Speaker 1: the zygotic stage of development. Right. So that means a

207
00:12:00,920 --> 00:12:04,880
Speaker 1: non chicken and a non chicken got together and created

208
00:12:04,920 --> 00:12:08,600
Speaker 1: as I got that had a mutation that eventually turned

209
00:12:08,600 --> 00:12:12,000
Speaker 1: it into a chicken. Its jeans were expressed to be

210
00:12:12,160 --> 00:12:14,480
Speaker 1: a chicken. To the egg came first. The egg came

211
00:12:14,520 --> 00:12:17,320
Speaker 1: before the chicken. Eventually the egg hatched and you had

212
00:12:17,400 --> 00:12:20,440
Speaker 1: the first chicken. But the egg came first, all right, Um.

213
00:12:20,520 --> 00:12:23,559
Speaker 1: But the point of me saying that is that the

214
00:12:23,640 --> 00:12:28,200
Speaker 1: mutations that appear, these traits that change over time or

215
00:12:28,240 --> 00:12:31,840
Speaker 1: show up that make an animal more fit for its environment,

216
00:12:32,160 --> 00:12:37,160
Speaker 1: happened in the reproductive level of zygote, That's right. And

217
00:12:37,400 --> 00:12:40,720
Speaker 1: the accumulation of those traits, the beneficial traits that make

218
00:12:40,760 --> 00:12:43,959
Speaker 1: it able to survive UH in a certain place, like

219
00:12:44,040 --> 00:12:47,800
Speaker 1: a polar bear in the cold, is called an ecological niche.

220
00:12:48,120 --> 00:12:50,440
Speaker 1: Niche and some people say, we talked about the polar

221
00:12:50,440 --> 00:12:53,160
Speaker 1: bear before um separating from the Brown Bear and the

222
00:12:53,160 --> 00:12:56,040
Speaker 1: Black Bear and Evolution in Isolation, which was kind of

223
00:12:56,080 --> 00:13:00,280
Speaker 1: a companion podcast of this one. Did you write that one, Yeah,

224
00:13:00,280 --> 00:13:01,720
Speaker 1: I wrote that one. I didn't write this one that

225
00:13:01,760 --> 00:13:04,640
Speaker 1: this was the grabster. Yeah, that's right, of course. So

226
00:13:04,679 --> 00:13:09,319
Speaker 1: that's an ecological niche and um animals, like we mentioned

227
00:13:09,320 --> 00:13:11,200
Speaker 1: the polar bear, that have adapted to live in a

228
00:13:11,200 --> 00:13:12,800
Speaker 1: cold area. You throw a polar bear out in the

229
00:13:13,600 --> 00:13:17,319
Speaker 1: savannah of Africa and it's not gonna do too well, right,

230
00:13:17,440 --> 00:13:20,440
Speaker 1: which brings up another point I think that is there's

231
00:13:20,440 --> 00:13:22,720
Speaker 1: a lesson in all of this what we're talking about,

232
00:13:22,880 --> 00:13:27,520
Speaker 1: especially with ecological niches. We especially us being humans at

233
00:13:27,520 --> 00:13:29,439
Speaker 1: the top of the food chain and the smartest things

234
00:13:29,520 --> 00:13:33,920
Speaker 1: ever since slight spread um or prairie dogs go ahead, okay,

235
00:13:34,160 --> 00:13:38,800
Speaker 1: tend to look at evolution as um basically a ladder

236
00:13:39,080 --> 00:13:42,960
Speaker 1: and we're at the top, baby, right, that's not the

237
00:13:43,000 --> 00:13:46,480
Speaker 1: case an ecological niches point that point that out. If

238
00:13:46,520 --> 00:13:50,439
Speaker 1: you if humans okay, great example, if you take a

239
00:13:50,520 --> 00:13:52,880
Speaker 1: human and put it at the bottom of the Marianna trench,

240
00:13:53,040 --> 00:13:55,960
Speaker 1: it's not going to thrive, It's going to drown or

241
00:13:55,960 --> 00:13:58,760
Speaker 1: its heads going to explode. We're not suited for it.

242
00:13:59,000 --> 00:14:02,280
Speaker 1: So we're not evolved. We're not at the top of evolution.

243
00:14:02,480 --> 00:14:04,640
Speaker 1: If evolution were a ladder and we were at the top,

244
00:14:04,679 --> 00:14:07,280
Speaker 1: we'd be suited for any environment. We're not at a

245
00:14:07,360 --> 00:14:10,559
Speaker 1: good point. So, as a guy named Matt Ridley points

246
00:14:10,559 --> 00:14:13,120
Speaker 1: out in a book called The Red Queen, Sex and

247
00:14:13,160 --> 00:14:16,680
Speaker 1: the Evolution of Human Nature, um that evolution is not

248
00:14:17,440 --> 00:14:22,320
Speaker 1: a ladder, it is a treadmill. Yeah. No, animals necessarily

249
00:14:22,400 --> 00:14:25,880
Speaker 1: better than another more highly evolved. It has to do

250
00:14:25,960 --> 00:14:30,760
Speaker 1: with adapting to your local environment. That's one of the

251
00:14:30,800 --> 00:14:35,160
Speaker 1: processes of parallel evolution. Makes sense. We adapt to our

252
00:14:35,200 --> 00:14:39,760
Speaker 1: local environment or our ecological niche. That's right. That's a

253
00:14:39,840 --> 00:14:41,640
Speaker 1: very good point. And the reason we're pointing out ecological

254
00:14:41,720 --> 00:14:44,600
Speaker 1: niche to begin with is because animals are I'm sorry

255
00:14:44,680 --> 00:14:51,200
Speaker 1: organisms period that have parallel or convergent evolution are usually

256
00:14:51,920 --> 00:14:55,560
Speaker 1: or more likely to have a similar ecological niche. It's

257
00:14:55,600 --> 00:15:00,800
Speaker 1: a really really long way of putting that, was it. Yeah. Uh.

258
00:15:00,920 --> 00:15:03,480
Speaker 1: For instance, you look at um an animal like the

259
00:15:03,520 --> 00:15:08,440
Speaker 1: wildebeeste or North American cattle, they're actually sort of parallel

260
00:15:08,640 --> 00:15:13,320
Speaker 1: evolutionized and they because they live in very similar areas.

261
00:15:13,360 --> 00:15:17,200
Speaker 1: You know, planes, hot, grassy, and uh so they're really

262
00:15:17,200 --> 00:15:19,920
Speaker 1: similar in the end, even though they're on two different continents.

263
00:15:20,320 --> 00:15:24,600
Speaker 1: Number one evolutionized t shirt. Okay, okay, Number two, that's

264
00:15:24,600 --> 00:15:30,040
Speaker 1: absolutely right, all right, yeah, thank you, absolutely right? Right? Okay, great,

265
00:15:31,960 --> 00:15:33,720
Speaker 1: what do you think? I thought you said? Wrong? And

266
00:15:33,760 --> 00:15:39,440
Speaker 1: it's absolutely white? Okay, that's absolutely blite. But Josh, absolutely

267
00:15:39,880 --> 00:15:43,640
Speaker 1: sometimes convergent evolution does not depend on this ecological niche

268
00:15:44,320 --> 00:15:48,920
Speaker 1: because the trait is really advantageous for all kinds of organisms.

269
00:15:49,240 --> 00:15:54,880
Speaker 1: And that's when you brought up the sharp teeth, limbs, wings, arms.

270
00:15:55,480 --> 00:15:59,160
Speaker 1: Consider this the arms. Uh we can say now looking

271
00:15:59,200 --> 00:16:05,960
Speaker 1: at Jean Ms, that arms are a direct relative of fins.

272
00:16:06,800 --> 00:16:09,320
Speaker 1: This again goes to the idea that evolution is a treadmill,

273
00:16:09,400 --> 00:16:11,960
Speaker 1: not a ladder. Right, So it's not like arms are

274
00:16:12,120 --> 00:16:17,920
Speaker 1: the inevitable and of fins. What are you laughing about.

275
00:16:18,520 --> 00:16:21,920
Speaker 1: It's that fins are better suited for swimming around the water. Right.

276
00:16:22,120 --> 00:16:24,800
Speaker 1: But the same genes, the same genetics set, the same

277
00:16:24,880 --> 00:16:28,640
Speaker 1: genetic code that give you fins also give you arms

278
00:16:28,640 --> 00:16:31,400
Speaker 1: if you're walking around, maybe swinging from trees or need

279
00:16:31,480 --> 00:16:34,040
Speaker 1: to climb them, or need to like, you know, high

280
00:16:34,040 --> 00:16:39,200
Speaker 1: five somebody to keep society going right. Yeah, yeah, same thing. Yeah,

281
00:16:39,200 --> 00:16:41,960
Speaker 1: you're right, but you know, we're not the only things

282
00:16:42,040 --> 00:16:45,720
Speaker 1: that evolved limbs. But limbs are so advantageous, just like

283
00:16:45,800 --> 00:16:49,720
Speaker 1: teeth um that we are. That a lot of different,

284
00:16:49,800 --> 00:16:55,160
Speaker 1: completely unrelated species evolved limbs to walk and to grab things.

285
00:16:55,200 --> 00:17:00,040
Speaker 1: And which is what is that convergent evolution? Yes, I

286
00:17:00,080 --> 00:17:02,800
Speaker 1: would say so we're the very least parallel. You know.

287
00:17:02,840 --> 00:17:07,000
Speaker 1: I have to say I'm surprising myself, extremely passionate for

288
00:17:07,080 --> 00:17:09,520
Speaker 1: this one. I don't understand why. Well, it's cool. And

289
00:17:09,560 --> 00:17:12,360
Speaker 1: you know, we haven't covered evolution in Earnest as a podcast,

290
00:17:12,400 --> 00:17:14,760
Speaker 1: but we've hit on it in so many I think

291
00:17:14,760 --> 00:17:16,840
Speaker 1: we're covering it in the long run one way or

292
00:17:16,840 --> 00:17:18,679
Speaker 1: the other. You know what I think it is. I

293
00:17:18,680 --> 00:17:21,600
Speaker 1: am just barely hanging on by my fingernails. So I'm

294
00:17:21,680 --> 00:17:24,000
Speaker 1: really like, yeah, if I say it really fast, it'll

295
00:17:24,440 --> 00:17:26,800
Speaker 1: it'll be right. All right. Let's talk about genetics in

296
00:17:26,840 --> 00:17:30,520
Speaker 1: this whole mess a parallel evolution. There are two things

297
00:17:30,600 --> 00:17:32,760
Speaker 1: to think about when you think about genetics, and the

298
00:17:32,760 --> 00:17:35,400
Speaker 1: first one, I think it's kind of cool. The genetic

299
00:17:35,440 --> 00:17:42,720
Speaker 1: code for species potentially has a hidden blueprint almost for

300
00:17:42,760 --> 00:17:46,679
Speaker 1: what it could do but not necessarily does do. And

301
00:17:46,720 --> 00:17:48,879
Speaker 1: the grab stre likned it too. Let's say you have

302
00:17:48,880 --> 00:17:51,520
Speaker 1: a blueprint of a house and the architect designed it

303
00:17:51,600 --> 00:17:55,040
Speaker 1: such that you can add on a master bedroom here

304
00:17:55,040 --> 00:17:57,920
Speaker 1: in this spot, but you never do it. But it's there.

305
00:17:57,960 --> 00:18:00,359
Speaker 1: You've got the land and the blueprint it for it.

306
00:18:00,400 --> 00:18:03,240
Speaker 1: You just don't use it right because the architects said,

307
00:18:03,480 --> 00:18:05,520
Speaker 1: don't build that edition yet they don't have the money

308
00:18:05,520 --> 00:18:07,440
Speaker 1: for it. They're just building the house exactly. But it

309
00:18:07,520 --> 00:18:09,639
Speaker 1: still exists in the in the master blueprint. And the

310
00:18:09,680 --> 00:18:12,880
Speaker 1: same can be said of let's say a jellyfish, which

311
00:18:12,920 --> 00:18:15,560
Speaker 1: is round right. There's no right or left side of

312
00:18:15,560 --> 00:18:20,160
Speaker 1: a sea and and and and intomy has radial symmetry, right,

313
00:18:20,200 --> 00:18:23,760
Speaker 1: a jellyfish or an anemony so hard for me? Anemone

314
00:18:24,560 --> 00:18:29,560
Speaker 1: show off an enemy now it's not an enemy, uhete

315
00:18:29,560 --> 00:18:32,160
Speaker 1: and chuck. There is no left or right side as

316
00:18:32,160 --> 00:18:35,639
Speaker 1: a radial body plan. It's circular and which is not

317
00:18:35,720 --> 00:18:38,200
Speaker 1: a funny shape at all. And the genetic code, though

318
00:18:38,280 --> 00:18:42,760
Speaker 1: is there. So eventually, one day, let's say the jellyfish

319
00:18:42,880 --> 00:18:45,399
Speaker 1: needed to evolve to have a left or right side

320
00:18:45,640 --> 00:18:48,679
Speaker 1: for some reason, it could do that genetically speaking, the

321
00:18:48,680 --> 00:18:51,840
Speaker 1: code is there. Yeah, for bilateral symmetry, which I have,

322
00:18:51,960 --> 00:18:54,200
Speaker 1: which you have? That you could as down the middle.

323
00:18:54,920 --> 00:18:58,640
Speaker 1: We could be folded in half. Yes, if you put

324
00:18:58,720 --> 00:19:03,119
Speaker 1: a mirror up to your knows perpendicular to your nose, no,

325
00:19:03,240 --> 00:19:06,080
Speaker 1: parallel to your nose, the point of your nose, it

326
00:19:06,080 --> 00:19:09,160
Speaker 1: would be half. It looked like you. That's right, right,

327
00:19:09,280 --> 00:19:12,840
Speaker 1: you know they say symmetry equals beauty. Yes, that's what

328
00:19:12,880 --> 00:19:15,440
Speaker 1: they say. That's what a lot of people say. Um,

329
00:19:15,760 --> 00:19:18,840
Speaker 1: you've got a big walleye on one side. That's why

330
00:19:18,840 --> 00:19:21,440
Speaker 1: you're not attractive. What are you going after? The eyes?

331
00:19:22,160 --> 00:19:29,080
Speaker 1: You mentioned disco? I'm another recent podcast, did somebody Okay? So,

332
00:19:29,080 --> 00:19:32,040
Speaker 1: so jellyfish have radio symmetry, but they have a genetic

333
00:19:32,400 --> 00:19:35,680
Speaker 1: marker to kick in bilateral symmetry they ever need it,

334
00:19:35,720 --> 00:19:39,760
Speaker 1: and believe me, I would run horrified from Maybe that's

335
00:19:39,760 --> 00:19:43,439
Speaker 1: what Cathulhu is. It's a it's a jellyfish who's like

336
00:19:43,480 --> 00:19:47,399
Speaker 1: bilateral symmetry has started to kick in a little bit. Nice. Um.

337
00:19:47,560 --> 00:19:51,359
Speaker 1: The point is is it's not just jellyfish. There are

338
00:19:51,400 --> 00:19:54,400
Speaker 1: a lot of dormant jeans just ready to go off

339
00:19:54,440 --> 00:19:57,879
Speaker 1: with the right mutation um to change all sorts of

340
00:19:57,920 --> 00:20:00,080
Speaker 1: stuff and they think. Also, I read the article that

341
00:20:00,160 --> 00:20:03,840
Speaker 1: he cited, the art technical article that the jellyfish have

342
00:20:03,960 --> 00:20:07,879
Speaker 1: that so that they can develop their mouth. Yeah, cool,

343
00:20:08,160 --> 00:20:13,359
Speaker 1: because the mouth requires bilateral symmetry jellyfish. The reason we

344
00:20:13,359 --> 00:20:16,680
Speaker 1: mentioned this to begin with, though, is that the belief

345
00:20:16,760 --> 00:20:20,600
Speaker 1: that you can develop similar traits even though you evolve separately,

346
00:20:20,640 --> 00:20:22,240
Speaker 1: which is what we've been talking about this whole time,

347
00:20:22,600 --> 00:20:24,880
Speaker 1: because the trait has always been in your genetic code

348
00:20:24,880 --> 00:20:28,360
Speaker 1: to begin with, just dormant, right, it's just very very ancient,

349
00:20:29,119 --> 00:20:31,680
Speaker 1: and then it can express in different ways, like apparently

350
00:20:31,720 --> 00:20:35,880
Speaker 1: they looked at the fins of a fish, right and

351
00:20:35,960 --> 00:20:38,639
Speaker 1: found that they have pretty much the same genes that

352
00:20:38,680 --> 00:20:43,400
Speaker 1: we do for our arms, okay, and bilateral symmetry. Those

353
00:20:43,480 --> 00:20:46,680
Speaker 1: genes are the same for everything. Right, So we're all

354
00:20:46,720 --> 00:20:49,840
Speaker 1: a lot more related, I guess than we thought now

355
00:20:49,880 --> 00:20:52,000
Speaker 1: that we're starting to look into it. I wonder if,

356
00:20:52,119 --> 00:20:53,680
Speaker 1: well we probably know this by now, if we have

357
00:20:53,720 --> 00:20:57,600
Speaker 1: any dormant genetic codes and humans like, we could potentially

358
00:20:57,640 --> 00:21:00,280
Speaker 1: grow that tail if we needed to. Well, apparently we

359
00:21:00,480 --> 00:21:05,040
Speaker 1: do have tales in some embryotic development stage. We still

360
00:21:05,040 --> 00:21:07,640
Speaker 1: have distigial tales, and there are people who are born

361
00:21:07,640 --> 00:21:10,400
Speaker 1: with him who don't shed them. That's pretty cool. Who

362
00:21:10,800 --> 00:21:13,600
Speaker 1: had the tale? Uh? Jason Alexander had one in one

363
00:21:13,640 --> 00:21:17,280
Speaker 1: of the Fairly Brothers movies. Yeah, we're like, if it

364
00:21:17,400 --> 00:21:20,200
Speaker 1: was was it? There's something there's something about Mary. Wasn't it? No, No,

365
00:21:20,440 --> 00:21:24,359
Speaker 1: he wouldn't in that. Are you sure that wasn't it? Yes?

366
00:21:24,520 --> 00:21:26,639
Speaker 1: Thank you? Yeah, yeah, that's what I meant to. Didn't

367
00:21:26,640 --> 00:21:29,080
Speaker 1: one of the friends have a tale? No? No, no,

368
00:21:29,160 --> 00:21:33,159
Speaker 1: Channel had a third nipple? Yes, superfluous Nipplesony Krusty the clown.

369
00:21:34,520 --> 00:21:37,800
Speaker 1: He so, Josh, what's the second thing to consider? Well,

370
00:21:37,800 --> 00:21:42,040
Speaker 1: I guess the other thing we've been what got biologists

371
00:21:42,440 --> 00:21:44,879
Speaker 1: into the idea of looking at jeans is that we

372
00:21:44,880 --> 00:21:47,840
Speaker 1: were looking at morphological changes, right. Stuff we can see

373
00:21:48,520 --> 00:21:51,240
Speaker 1: like this flying squirrel is not related to that flying squirrel,

374
00:21:51,280 --> 00:21:53,240
Speaker 1: but they're both flying squirrels, even though we call them

375
00:21:53,240 --> 00:21:58,080
Speaker 1: different things. Philanders um. When we look at the genetic level,

376
00:21:58,119 --> 00:22:02,359
Speaker 1: we're finding that like the same morphological traits, the similarities

377
00:22:02,720 --> 00:22:06,440
Speaker 1: are are also found on the genetic level, right, So

378
00:22:06,480 --> 00:22:10,320
Speaker 1: basically they're thinking, like you can you can look at

379
00:22:10,560 --> 00:22:15,160
Speaker 1: the ecological pressure, the environmental pressure that caused a polar

380
00:22:15,200 --> 00:22:21,520
Speaker 1: bears coat to become white right um on an internal

381
00:22:21,600 --> 00:22:25,760
Speaker 1: level with the interactions between amino acids and proteins that

382
00:22:25,840 --> 00:22:30,280
Speaker 1: are causing these genes to be expressed, so internally and externally,

383
00:22:30,600 --> 00:22:36,359
Speaker 1: these changes are are occurring um to form flying filangers

384
00:22:36,440 --> 00:22:39,880
Speaker 1: and squirrels on two different continents. Thank you the freak

385
00:22:39,920 --> 00:22:43,600
Speaker 1: show that is Australia for basically pointing science in the

386
00:22:43,680 --> 00:22:45,720
Speaker 1: right direction. They love it when we talk about them too.

387
00:22:45,720 --> 00:22:48,119
Speaker 1: We always get email from masses that are just like you.

388
00:22:48,119 --> 00:22:51,800
Speaker 1: Guys are the best. Another and they gave us another

389
00:22:51,800 --> 00:22:57,440
Speaker 1: one too. Um the Tasmanian wolf now extinct wolf which

390
00:22:57,520 --> 00:23:01,320
Speaker 1: is um almost completely unre related to any other wolf.

391
00:23:01,480 --> 00:23:05,520
Speaker 1: It's extinct, like I said, um, but it is the

392
00:23:05,720 --> 00:23:09,720
Speaker 1: spitting image of the gray wolf here in North America,

393
00:23:10,119 --> 00:23:13,480
Speaker 1: even though they're like they were not related, same everything.

394
00:23:14,240 --> 00:23:17,600
Speaker 1: This is the kind of science I dig. Yeah, cool science. Yeah,

395
00:23:18,640 --> 00:23:23,040
Speaker 1: not that physics magnetism. You're into physics that sort of

396
00:23:25,000 --> 00:23:27,119
Speaker 1: just that a necessity, I guess. Yeah, but you you

397
00:23:27,160 --> 00:23:29,760
Speaker 1: have an appreciation more than I do. I think. Really, Yeah,

398
00:23:29,960 --> 00:23:32,400
Speaker 1: you don't like full crumbs? What is wrong with what's

399
00:23:32,400 --> 00:23:36,680
Speaker 1: the full crumb? The full crumb is the point it's

400
00:23:36,680 --> 00:23:39,560
Speaker 1: like a see saw, right, and that the full crumb. Yeah, okay,

401
00:23:39,640 --> 00:23:41,680
Speaker 1: it's the it's the point of balance on a on

402
00:23:41,760 --> 00:23:45,920
Speaker 1: a sea saw. It's the point that he saw balance. Yeah, yeah,

403
00:23:46,080 --> 00:23:50,200
Speaker 1: same thing. You got anything else? Are we just gonna

404
00:23:50,200 --> 00:23:53,440
Speaker 1: evolve separately? Here? I think? So? Okay, if you want

405
00:23:53,440 --> 00:23:57,320
Speaker 1: to learn more about evolution, UM, you should type in

406
00:23:57,359 --> 00:24:00,640
Speaker 1: evolution in the search part how stuff works dot com. Um.

407
00:24:00,720 --> 00:24:04,879
Speaker 1: Also check out can animals evolve in isolation? That's a

408
00:24:04,920 --> 00:24:07,800
Speaker 1: cool article, Um, This article we've been talking about from

409
00:24:07,800 --> 00:24:11,560
Speaker 1: the grabster, How can two seemingly unrelated species that live

410
00:24:11,560 --> 00:24:15,000
Speaker 1: in isolation from each other evolve into identical forms? You

411
00:24:15,040 --> 00:24:18,919
Speaker 1: can also reach it by typing in parallel evolution in

412
00:24:18,960 --> 00:24:22,000
Speaker 1: the search bart how stuff works dot Com. So there's

413
00:24:22,040 --> 00:24:24,880
Speaker 1: a lot for you to go check out there, all right? Yeah,

414
00:24:24,880 --> 00:24:26,760
Speaker 1: And I would say just type in evolution and how

415
00:24:26,800 --> 00:24:28,720
Speaker 1: stuff works, and you're gonna get a whole bevy of

416
00:24:28,840 --> 00:24:31,880
Speaker 1: cool cool stuff. That's what I said first. Yeah, I'm

417
00:24:31,920 --> 00:24:36,840
Speaker 1: reinforcing that well, Chuck said search bart how stuff works? Right, Yeah,

418
00:24:37,000 --> 00:24:39,760
Speaker 1: I did too. It means it's super super time for

419
00:24:40,080 --> 00:24:46,440
Speaker 1: listener mail. That's right, Josh, I'm gonna call this um

420
00:24:47,680 --> 00:24:53,160
Speaker 1: Mountaintop removable coal mining email from an inside one of millions. Yeah,

421
00:24:53,200 --> 00:24:54,840
Speaker 1: we got a lot of positive feedback from this, and

422
00:24:55,440 --> 00:24:57,880
Speaker 1: surprisingly not one person is written in yet that said,

423
00:24:58,320 --> 00:25:00,720
Speaker 1: you jerks. You never think about the the minor side

424
00:25:00,720 --> 00:25:03,240
Speaker 1: of things. Most people have been like, yeah, this is

425
00:25:03,280 --> 00:25:06,600
Speaker 1: probably shouldn't be. Some some guy on Twitter basically said

426
00:25:06,920 --> 00:25:09,679
Speaker 1: I don't like it when they get political, but this

427
00:25:09,760 --> 00:25:12,400
Speaker 1: one was pretty good. All right, Yeah, I'll take that. Man.

428
00:25:12,880 --> 00:25:14,879
Speaker 1: Hey guys, I've heard all your podcasts from day one,

429
00:25:14,880 --> 00:25:17,679
Speaker 1: and keep up the good work. Please. Uh sometimes you

430
00:25:17,680 --> 00:25:19,439
Speaker 1: are all I need to get away from the day's stress.

431
00:25:19,800 --> 00:25:23,680
Speaker 1: I mean mining engineers. Student enrolled at the University of

432
00:25:23,760 --> 00:25:28,479
Speaker 1: Kentucky Go Wildcats, one of the largest exporters of eager

433
00:25:29,040 --> 00:25:32,600
Speaker 1: and to do mining engineers. In reality, the decision to

434
00:25:32,680 --> 00:25:35,640
Speaker 1: enroll here had more to do with scholarship opportunities than

435
00:25:35,680 --> 00:25:39,320
Speaker 1: a lifelong love of Appalachian mining. However, after being surrounded

436
00:25:39,320 --> 00:25:42,240
Speaker 1: by over zealous students who would personally blow up the

437
00:25:42,240 --> 00:25:44,560
Speaker 1: earth for an ounce of coal because it keeps the

438
00:25:44,680 --> 00:25:48,320
Speaker 1: lights on, I have become entirely infatuated with this mindset.

439
00:25:48,760 --> 00:25:51,359
Speaker 1: I've interviewed for all the big name companies some of

440
00:25:51,359 --> 00:25:55,280
Speaker 1: which spend hundreds of thousands of dollars recruiting new workforce.

441
00:25:56,000 --> 00:25:58,040
Speaker 1: When I interviewed for these companies, they seem to be

442
00:25:58,080 --> 00:26:02,159
Speaker 1: in complete denial of this satistics, occasionally showing a picture

443
00:26:02,200 --> 00:26:04,000
Speaker 1: of a deer standing on a patch of grass and

444
00:26:04,040 --> 00:26:06,280
Speaker 1: claiming that it's as if we were never there in

445
00:26:06,280 --> 00:26:09,520
Speaker 1: the first place. As I have been shown firsthand what

446
00:26:09,600 --> 00:26:13,359
Speaker 1: the mining field entails, I have nothing but devout respect

447
00:26:13,400 --> 00:26:15,600
Speaker 1: for what these people do on a daily basis. And

448
00:26:15,600 --> 00:26:17,640
Speaker 1: that's something I don't know. If we make clear we're

449
00:26:17,640 --> 00:26:21,760
Speaker 1: not anti minors, we know these people were very thin. Yeah,

450
00:26:22,359 --> 00:26:24,280
Speaker 1: I have nothing but devout respect for what these people

451
00:26:24,320 --> 00:26:26,119
Speaker 1: do on a daily basis to make sure that I

452
00:26:26,160 --> 00:26:30,200
Speaker 1: can send this email on my electricity powered laptop. At

453
00:26:30,200 --> 00:26:33,359
Speaker 1: the same time, I shudder in disappointment that they wishfully

454
00:26:33,400 --> 00:26:36,040
Speaker 1: remain ignorant of the science involved in the harm they

455
00:26:36,080 --> 00:26:38,600
Speaker 1: are doing. Part of me wishes to enter the field

456
00:26:38,600 --> 00:26:41,919
Speaker 1: to reinvent the idea that providing energy must come at
