1
00:00:01,160 --> 00:00:04,120
Speaker 1: Welcome to Stuff You Missed in History Class from how

2
00:00:04,160 --> 00:00:15,160
Speaker 1: Stuff Works dot com. Hello, and welcome to the podcast.

3
00:00:15,360 --> 00:00:19,200
Speaker 1: I'm Tray, Steve Wilson, and I'm Holly Frying. So the

4
00:00:19,239 --> 00:00:24,520
Speaker 1: Piltdown Man one of the world's most infamous instances in

5
00:00:24,600 --> 00:00:29,360
Speaker 1: scientific fraud, and in August of which is this year,

6
00:00:30,000 --> 00:00:34,199
Speaker 1: researchers published a paper in Royal Society Open Science that

7
00:00:34,320 --> 00:00:36,919
Speaker 1: concluded that it was the work of a single hoaxer.

8
00:00:37,600 --> 00:00:42,640
Speaker 1: So rather than rolling that into our Unearthed episodes, which

9
00:00:42,680 --> 00:00:45,400
Speaker 1: are just around the corner, we are doing an entire

10
00:00:45,600 --> 00:00:50,000
Speaker 1: Unearthed episode just on this. Uh. We're going to talk

11
00:00:50,040 --> 00:00:54,520
Speaker 1: about the pilt Down Man, how this hoax played out,

12
00:00:54,680 --> 00:00:57,840
Speaker 1: and what exactly was unearthed in this newly published paper

13
00:00:57,920 --> 00:01:01,360
Speaker 1: that inspired us to do the episode. Yeah. So that

14
00:01:01,480 --> 00:01:04,720
Speaker 1: we've gotten lots of requests for over the years. Yeah,

15
00:01:04,760 --> 00:01:06,360
Speaker 1: And for me, I've sort of had it on the

16
00:01:06,720 --> 00:01:09,640
Speaker 1: I'll get to that one day maybe list. And now

17
00:01:09,680 --> 00:01:11,399
Speaker 1: this is a time when I can be proud of

18
00:01:11,400 --> 00:01:14,920
Speaker 1: my procrastination because it enabled this cool thing to come out.

19
00:01:15,480 --> 00:01:20,119
Speaker 1: Well what what is? Uh? One of the things that's

20
00:01:20,160 --> 00:01:22,520
Speaker 1: intriguing to me is that I literally wrote this on

21
00:01:22,560 --> 00:01:26,319
Speaker 1: the list in August right that it has. I have

22
00:01:26,360 --> 00:01:29,479
Speaker 1: been planning to do this episode right now as of August,

23
00:01:30,840 --> 00:01:35,840
Speaker 1: and now it seems particularly relevant because it is such

24
00:01:35,840 --> 00:01:43,119
Speaker 1: a cautionary tale about not just uncritically observing absorbing things

25
00:01:43,360 --> 00:01:47,680
Speaker 1: that are announced as news. The whole time I was

26
00:01:47,720 --> 00:01:49,680
Speaker 1: working on this outline, I was like, this is this

27
00:01:49,800 --> 00:01:54,840
Speaker 1: feels like we just need a reminder so it makes

28
00:01:54,840 --> 00:01:57,400
Speaker 1: sense of why the pilt down hoax even happened in

29
00:01:57,440 --> 00:01:59,520
Speaker 1: the first place. We actually need to go all the

30
00:01:59,560 --> 00:02:03,160
Speaker 1: way back to Charles Darwin's publication of On the Origin

31
00:02:03,200 --> 00:02:06,960
Speaker 1: of Species in eighteen fifty nine. The full title of

32
00:02:07,000 --> 00:02:10,000
Speaker 1: that particular writing is on the Origin of Species by

33
00:02:10,080 --> 00:02:14,160
Speaker 1: Means of Natural Selection or the Preservation of favored races

34
00:02:14,240 --> 00:02:18,280
Speaker 1: in the Struggle for Life, and this details Darwin's theories

35
00:02:18,320 --> 00:02:21,280
Speaker 1: of evolution by natural selection, which are at the foundation

36
00:02:21,440 --> 00:02:26,720
Speaker 1: of evolutionary biology. When he published this book, Darwin knew

37
00:02:26,840 --> 00:02:29,280
Speaker 1: that one type of evidence that would really support his

38
00:02:29,360 --> 00:02:33,680
Speaker 1: theories was in relatively short supply, and that is transitional fossils.

39
00:02:34,280 --> 00:02:37,080
Speaker 1: These are fossils that have some traits belonging to an

40
00:02:37,120 --> 00:02:40,800
Speaker 1: older species and some belonging to a more modern species.

41
00:02:41,240 --> 00:02:46,200
Speaker 1: And transitional fossils are physical evidence of an intermediary evolutionary

42
00:02:46,240 --> 00:02:51,760
Speaker 1: step that demonstrates how life is changing over time. One

43
00:02:51,800 --> 00:02:56,200
Speaker 1: famous example of a transitional fossil is archaeopterics. It's got

44
00:02:56,280 --> 00:02:59,240
Speaker 1: some features that are more like a reptile and others

45
00:02:59,240 --> 00:03:01,839
Speaker 1: that are more like a bird, and today it's viewed

46
00:03:01,880 --> 00:03:06,160
Speaker 1: as a transitional fossil between non avian dinosaurs and modern birds.

47
00:03:07,160 --> 00:03:10,640
Speaker 1: Darwin knew that people would try to discredit his work

48
00:03:10,760 --> 00:03:14,640
Speaker 1: because at that point in history, not that many transitional

49
00:03:14,680 --> 00:03:18,959
Speaker 1: fossils had been found. Archaeotrics, for example, would not even

50
00:03:19,000 --> 00:03:22,079
Speaker 1: be discovered until eighteen sixty, and a lot of people

51
00:03:22,360 --> 00:03:26,040
Speaker 1: at that point described it more as the first bird

52
00:03:26,240 --> 00:03:29,880
Speaker 1: rather than as a transitional fossil. Six of course, was

53
00:03:29,919 --> 00:03:33,359
Speaker 1: after his book had already been published, but Darwin actually

54
00:03:33,400 --> 00:03:38,680
Speaker 1: anticipated actually these exact source of discoveries. He explained in

55
00:03:38,720 --> 00:03:41,960
Speaker 1: the Origin of Species that this lack of evidence was

56
00:03:42,040 --> 00:03:45,640
Speaker 1: probably due to an incomplete geological record and not to

57
00:03:45,800 --> 00:03:49,760
Speaker 1: an actual absence of the fossils that would prove him Right.

58
00:03:51,080 --> 00:03:54,760
Speaker 1: After Darwin's publication of On the Origin of Species, there

59
00:03:54,840 --> 00:03:59,360
Speaker 1: was a big focus on finding more transitional fossils. In particular,

60
00:03:59,440 --> 00:04:02,760
Speaker 1: people were hoping to find the missing link, that single

61
00:04:02,800 --> 00:04:06,800
Speaker 1: fossil that would conclusively demonstrate a connection between ancient apes

62
00:04:06,880 --> 00:04:11,920
Speaker 1: and modern humans. Today, we know about lots of transitional

63
00:04:12,000 --> 00:04:15,760
Speaker 1: fossils that detailed the progression of all kinds of life.

64
00:04:16,080 --> 00:04:19,200
Speaker 1: We have transitional fossils and the evolutionary family trees of

65
00:04:19,240 --> 00:04:22,200
Speaker 1: birds and fish and whales and horses and elephants and

66
00:04:22,360 --> 00:04:27,800
Speaker 1: on and on. I literally could just randomly name animals.

67
00:04:27,880 --> 00:04:31,239
Speaker 1: That's the thirty minute podcast episode is just Tracy saying

68
00:04:31,279 --> 00:04:34,560
Speaker 1: animal words. It starts to sound like the list of

69
00:04:34,600 --> 00:04:37,360
Speaker 1: what they were eating in Monty Python in the Holy Grail.

70
00:04:37,520 --> 00:04:41,359
Speaker 1: So in terms of human life, the idea of a

71
00:04:41,560 --> 00:04:46,040
Speaker 1: single missing link between ancient hominids and modern humans has

72
00:04:46,080 --> 00:04:49,480
Speaker 1: really vanished under the weight of a lot of individual

73
00:04:49,560 --> 00:04:52,720
Speaker 1: transitional fossils that add up to a human family tree

74
00:04:52,760 --> 00:04:55,880
Speaker 1: that's full of forks and branches. It is not a

75
00:04:56,040 --> 00:05:00,320
Speaker 1: single linear, one lane road that starts on a and

76
00:05:00,480 --> 00:05:05,600
Speaker 1: ends on human connected with one magical quote missing link fossil.

77
00:05:06,000 --> 00:05:09,080
Speaker 1: It's a lot more complicated than that. Yeah. Uh. In

78
00:05:09,160 --> 00:05:11,840
Speaker 1: nineteen twelves, though, the missing link would have been an

79
00:05:11,839 --> 00:05:16,599
Speaker 1: earth shattering, groundbreaking and career making discovery, and that is

80
00:05:16,640 --> 00:05:20,159
Speaker 1: what brings us to pilt Down Man. In February of

81
00:05:20,240 --> 00:05:24,080
Speaker 1: nineteen twelve, Sir Arthur Smith Woodward, keeper of geology at

82
00:05:24,080 --> 00:05:27,120
Speaker 1: the British Museum now called the Natural History Museum, got

83
00:05:27,120 --> 00:05:31,040
Speaker 1: a letter from Charles Dawson. In addition to being a solicitor,

84
00:05:31,320 --> 00:05:34,160
Speaker 1: Dawson was an amateur archaeologist, and he said he had

85
00:05:34,200 --> 00:05:38,520
Speaker 1: found something very exciting in some gravel beds and pilt Down, Sussex.

86
00:05:39,400 --> 00:05:42,680
Speaker 1: According to Dawson's account, he had noticed that a road

87
00:05:42,680 --> 00:05:45,480
Speaker 1: where he lived had been repaired with some odd flints,

88
00:05:46,080 --> 00:05:48,599
Speaker 1: and he traced the flints to their source, which turned

89
00:05:48,600 --> 00:05:51,960
Speaker 1: out to be a shallow gravel bed. While talking the

90
00:05:51,960 --> 00:05:54,080
Speaker 1: workers there, he learned that they dug up something they

91
00:05:54,160 --> 00:05:57,719
Speaker 1: described as quote like a coconut, and that they'd thrown

92
00:05:57,760 --> 00:06:01,599
Speaker 1: the pieces away. Dawson dug these fragments out of the

93
00:06:01,640 --> 00:06:04,039
Speaker 1: trash and found that they were part of a skull,

94
00:06:04,680 --> 00:06:06,960
Speaker 1: and over the next couple of years he'd gone back

95
00:06:07,000 --> 00:06:09,640
Speaker 1: to the pit and found several other pieces of skull

96
00:06:09,720 --> 00:06:13,599
Speaker 1: and jaw bone before finally writing his letter to Smith Woodward.

97
00:06:14,800 --> 00:06:17,760
Speaker 1: Uh these skull fragments and jaw bone, he described, looked

98
00:06:17,920 --> 00:06:22,040
Speaker 1: somewhat human, but not exactly, and his letter he compared

99
00:06:22,120 --> 00:06:24,760
Speaker 1: his discovery to a jaw bone that had been discovered

100
00:06:24,800 --> 00:06:27,360
Speaker 1: by a workman in a sand pit near Heidelberg, Germany,

101
00:06:27,400 --> 00:06:31,800
Speaker 1: in nineteen oh seven, which had been named Homo heidelberg insis.

102
00:06:31,839 --> 00:06:36,920
Speaker 1: In Homo heidelberg insis had some features in common with

103
00:06:36,960 --> 00:06:40,039
Speaker 1: Homo erectus and others in common with modern humans or

104
00:06:40,040 --> 00:06:44,640
Speaker 1: Homo sapiens. Dawson said his discovery quote would quote rival

105
00:06:44,920 --> 00:06:50,520
Speaker 1: h heidelberg Insis in solidity. Dawson and Smith Woodward kept

106
00:06:50,640 --> 00:06:53,240
Speaker 1: quiet about this find at first as they did some

107
00:06:53,320 --> 00:06:56,400
Speaker 1: more digging at the pit, and then they presented their

108
00:06:56,400 --> 00:06:59,599
Speaker 1: findings to a packed meeting of the Geological Society of

109
00:06:59,680 --> 00:07:03,760
Speaker 1: London on December eighteenth of nineteen twelve. They had an

110
00:07:03,800 --> 00:07:07,680
Speaker 1: ape like mandible or jawbone. Two of its molars were

111
00:07:07,680 --> 00:07:11,080
Speaker 1: in place and had significant wear, and then there were

112
00:07:11,120 --> 00:07:13,960
Speaker 1: pieces of the brain case of a skull, which seemed

113
00:07:13,960 --> 00:07:17,080
Speaker 1: a lot more human than the mandible did. They had

114
00:07:17,080 --> 00:07:20,280
Speaker 1: also found some stone tools and fragments of other non

115
00:07:20,440 --> 00:07:24,520
Speaker 1: human mammal fossils. Their coloring was comparable to that of

116
00:07:24,560 --> 00:07:27,480
Speaker 1: the gravel bed, and the conclusion was that these fossils

117
00:07:27,480 --> 00:07:33,560
Speaker 1: were at least five hundred thousand years old. Regarding their presentation, A. C. Hadn't,

118
00:07:33,600 --> 00:07:36,680
Speaker 1: writing in the journal Science, said quote Mr Dawson gave

119
00:07:36,720 --> 00:07:39,200
Speaker 1: an account of the finding of the specimens, the nature

120
00:07:39,240 --> 00:07:43,080
Speaker 1: and geographical and geological position of the gravel bed, and

121
00:07:43,240 --> 00:07:47,360
Speaker 1: Dr Smith Woodward described the remains in a most excellent manner.

122
00:07:48,400 --> 00:07:50,840
Speaker 1: Hadn't went on to write, quote, there could be no

123
00:07:50,960 --> 00:07:53,760
Speaker 1: doubt that this is a discovery of the greatest importance

124
00:07:53,800 --> 00:07:56,760
Speaker 1: and will give rise to much discussion. It is the

125
00:07:56,800 --> 00:07:59,480
Speaker 1: nearest approach we have yet reached to a missing link.

126
00:08:00,040 --> 00:08:04,040
Speaker 1: Probably few will deny that EU Anthropist Dawson I is almost,

127
00:08:04,080 --> 00:08:07,640
Speaker 1: if not quite, as much human as Simian. I'm just

128
00:08:07,640 --> 00:08:09,680
Speaker 1: gonna say we are guessing on how that is pronounced,

129
00:08:09,720 --> 00:08:15,640
Speaker 1: because it seems like no one knows. So your Anthropist

130
00:08:15,720 --> 00:08:18,720
Speaker 1: Dawson I is what they've named their find, and that

131
00:08:18,760 --> 00:08:25,000
Speaker 1: means Dawson's dawn Man, which is not self congratulatory at all.

132
00:08:25,000 --> 00:08:27,720
Speaker 1: I mean, I know, often scientific names of things are

133
00:08:27,840 --> 00:08:32,200
Speaker 1: named after the person who found or discovered or put

134
00:08:32,200 --> 00:08:35,040
Speaker 1: them in a taxonomy or whatever, but like Dawson's dawn Man,

135
00:08:36,800 --> 00:08:40,800
Speaker 1: it just seems particularly back Patty Yeah uh in nineteen

136
00:08:40,840 --> 00:08:44,560
Speaker 1: thirteen and nineteen fourteen, excavations continued at the gravel pit

137
00:08:44,640 --> 00:08:48,760
Speaker 1: where these first fossils had reportedly been recovered, and these

138
00:08:48,800 --> 00:08:53,120
Speaker 1: excavations unearthed some other evidence as well. There was a

139
00:08:53,240 --> 00:08:56,160
Speaker 1: canine tooth which had some features in common with ape

140
00:08:56,160 --> 00:08:59,679
Speaker 1: teeth and others in common with modern human teeth. They

141
00:08:59,720 --> 00:09:02,760
Speaker 1: also found a carved slab of bone that became known

142
00:09:02,800 --> 00:09:05,480
Speaker 1: as the cricket bat because it was roughly shaped like one.

143
00:09:06,960 --> 00:09:09,880
Speaker 1: Although Dawson did keep excavating, or at least saying he

144
00:09:09,960 --> 00:09:12,480
Speaker 1: was excavating, the start of World War One meant that

145
00:09:12,520 --> 00:09:15,600
Speaker 1: it took place on a much smaller scale. He sent

146
00:09:15,640 --> 00:09:18,040
Speaker 1: a couple of postcards to Smith Woodward saying that he

147
00:09:18,080 --> 00:09:20,880
Speaker 1: had found some other fossils and other sites not far

148
00:09:20,920 --> 00:09:23,960
Speaker 1: away from that first find, but otherwise this was really

149
00:09:24,040 --> 00:09:26,559
Speaker 1: the end of the discoveries that pilt Down, and then

150
00:09:26,640 --> 00:09:31,120
Speaker 1: Dawson died in nineteen sixteen. A lot of scientists were

151
00:09:31,520 --> 00:09:36,280
Speaker 1: very excited about the pilt Down discoveries. Understandably, not only

152
00:09:36,320 --> 00:09:38,480
Speaker 1: were they put forth as the missing link that was

153
00:09:38,559 --> 00:09:41,800
Speaker 1: so important to evolutionary science at the time, but they

154
00:09:41,800 --> 00:09:44,439
Speaker 1: had also been found in Britain, which meant that the

155
00:09:44,480 --> 00:09:47,400
Speaker 1: British Isles had played an important part in the evolution

156
00:09:47,559 --> 00:09:51,080
Speaker 1: of all of humanity. The British Empire was at this

157
00:09:51,160 --> 00:09:54,960
Speaker 1: point the largest empire and human history, controlling almost one

158
00:09:55,040 --> 00:09:57,800
Speaker 1: quarter of all of the land on Earth. So the

159
00:09:57,840 --> 00:10:00,319
Speaker 1: idea that Britain had also been a key stone and

160
00:10:00,440 --> 00:10:04,680
Speaker 1: human evolution carried this mix of pride and of wealth. Obviously,

161
00:10:05,360 --> 00:10:08,280
Speaker 1: these people were quite ready to believe that Britain was

162
00:10:08,320 --> 00:10:11,800
Speaker 1: actually the birthplace of the human at the human species.

163
00:10:11,880 --> 00:10:17,440
Speaker 1: So although it was not universally accepted, the pilt Down

164
00:10:17,440 --> 00:10:20,960
Speaker 1: Man played a major role in scientific thought about human

165
00:10:20,960 --> 00:10:25,400
Speaker 1: evolution for about the next forty years. More than two

166
00:10:25,600 --> 00:10:28,280
Speaker 1: d and fifty papers and monographs were published about it,

167
00:10:28,280 --> 00:10:30,840
Speaker 1: and it was cited in more than seventy publications. So

168
00:10:30,920 --> 00:10:32,640
Speaker 1: it was a pretty big deal. And it was also

169
00:10:32,679 --> 00:10:35,960
Speaker 1: completely made up. We're going to talk about after a

170
00:10:35,960 --> 00:10:45,239
Speaker 1: sponsor break. So after this announcement, many in the scientific

171
00:10:45,240 --> 00:10:48,000
Speaker 1: community just took Dawson and Smith Woodward's report to the

172
00:10:48,000 --> 00:10:52,000
Speaker 1: Geological Society of London at face value. The original pieces

173
00:10:52,120 --> 00:10:55,120
Speaker 1: of these specimens were locked away in storage for safekeeping,

174
00:10:55,160 --> 00:10:58,520
Speaker 1: but casts of them were made to share with researchers

175
00:10:58,520 --> 00:11:01,960
Speaker 1: who wanted to do further stuff. A A lot of

176
00:11:02,000 --> 00:11:05,800
Speaker 1: the early scientific debate about these specimens didn't even consider

177
00:11:05,880 --> 00:11:09,680
Speaker 1: the basic question of whether they were authentic at all. Instead,

178
00:11:09,720 --> 00:11:12,720
Speaker 1: it was about things like whether smith Wouldwards interpretation of

179
00:11:12,720 --> 00:11:15,920
Speaker 1: the skull was correct. He had made a reconstruction of

180
00:11:15,960 --> 00:11:19,240
Speaker 1: the skull based on nine fragments that had initially been found.

181
00:11:19,679 --> 00:11:23,160
Speaker 1: The resulting skull had a capacity of about one thousand

182
00:11:23,120 --> 00:11:28,120
Speaker 1: and seventy six cubic centimeters to other anatomists and anthropologists

183
00:11:28,280 --> 00:11:33,280
Speaker 1: disagreed about whether Smith Wouldwards reconstruction was accurate. Sir Arthur

184
00:11:33,360 --> 00:11:35,640
Speaker 1: Keith of Scotland was on one side of this debate,

185
00:11:35,679 --> 00:11:38,560
Speaker 1: and Sir Grafton Elliott Smith of Australia was on the other.

186
00:11:39,120 --> 00:11:42,079
Speaker 1: Keith made his own reconstruction, which had a capacity of

187
00:11:42,120 --> 00:11:45,240
Speaker 1: about fifteen hundred cubic centimeters, or about the same as

188
00:11:45,240 --> 00:11:48,880
Speaker 1: a modern human skull, which prompted Smith Woodward to revise

189
00:11:49,000 --> 00:11:52,679
Speaker 1: his original reconstruction. Smith, on the other hand, came to

190
00:11:52,840 --> 00:11:56,880
Speaker 1: different conclusions, insisting that the original one thousand, seventy six

191
00:11:56,920 --> 00:11:59,600
Speaker 1: cubic centimeters was a lot more correct. These all had

192
00:11:59,640 --> 00:12:02,319
Speaker 1: to do with basically how the skull pieces were lined up.

193
00:12:02,320 --> 00:12:07,079
Speaker 1: And what parts of the skull bones people thought they

194
00:12:07,120 --> 00:12:10,480
Speaker 1: were from. Like you think of your skull as one

195
00:12:10,520 --> 00:12:14,040
Speaker 1: solid piece, but it's actually several pieces connected by sutures.

196
00:12:15,240 --> 00:12:18,520
Speaker 1: So the question was whether these nine fragments of skull

197
00:12:18,679 --> 00:12:22,559
Speaker 1: were being correctly used to make a reconstruction, not whether

198
00:12:22,600 --> 00:12:26,280
Speaker 1: they were actually from a prehistoric human. There was also

199
00:12:26,320 --> 00:12:28,439
Speaker 1: a lot of talk about whether the canine tooth that

200
00:12:28,520 --> 00:12:30,960
Speaker 1: was found later was really part of the same mandible

201
00:12:31,080 --> 00:12:34,480
Speaker 1: or not, but there was no talk about whether any

202
00:12:34,520 --> 00:12:39,000
Speaker 1: of these pieces were actually genuine. Basically, a big chunk

203
00:12:39,040 --> 00:12:42,800
Speaker 1: of the scientific literature surrounding this fine just was credulous

204
00:12:42,840 --> 00:12:46,280
Speaker 1: and uncritical from the start. And to be fair, many

205
00:12:46,400 --> 00:12:49,080
Speaker 1: of the technologies that we used to authenticate the age

206
00:12:49,080 --> 00:12:52,000
Speaker 1: of fossils today were not invented yet and they would

207
00:12:52,040 --> 00:12:54,680
Speaker 1: not be for more than twenty years. And also a

208
00:12:54,800 --> 00:12:57,680
Speaker 1: lot of the other fossil evidence today that we know

209
00:12:57,760 --> 00:13:02,280
Speaker 1: about that shows that hominids developed more humanlike jaws before

210
00:13:02,559 --> 00:13:06,160
Speaker 1: they developed developed bigger brain cases, those had not been

211
00:13:06,200 --> 00:13:08,960
Speaker 1: discovered yet either, so they didn't really have things to

212
00:13:09,000 --> 00:13:12,320
Speaker 1: compare them to you. But even so, a lot of

213
00:13:12,320 --> 00:13:15,160
Speaker 1: people studying this fine simply took for granted from the

214
00:13:15,160 --> 00:13:18,040
Speaker 1: beginning that it was legitimate, and they framed their study

215
00:13:18,120 --> 00:13:22,560
Speaker 1: from there, Like the quote popularized by Carl Sagan, Extraordinary

216
00:13:22,600 --> 00:13:25,079
Speaker 1: claims like I found the missing link in a gravel

217
00:13:25,080 --> 00:13:29,400
Speaker 1: pit and pilt down require extraordinary evidence, and that just

218
00:13:29,559 --> 00:13:34,200
Speaker 1: was not present here. This uncritical acceptance that the piltd

219
00:13:34,200 --> 00:13:38,320
Speaker 1: Down Man was real was certainly not completely universal, especially

220
00:13:38,360 --> 00:13:41,640
Speaker 1: as time passed and people had more opportunities to study it.

221
00:13:42,200 --> 00:13:46,000
Speaker 1: For example, American zoologist Garrett Smith Miller published quote the

222
00:13:46,080 --> 00:13:49,679
Speaker 1: Jaw of the Piltdown Man in Smithsonian Miscellaneous Collections in

223
00:13:49,800 --> 00:13:53,559
Speaker 1: nineteen fifteen, and which he concluded that the skull fragments

224
00:13:53,600 --> 00:13:56,080
Speaker 1: did come from a real human skull, but that the

225
00:13:56,200 --> 00:14:00,520
Speaker 1: mandible came from an extinct species of chimpanzee. Writing an

226
00:14:00,559 --> 00:14:05,120
Speaker 1: American anthropologist, William K. Gregory later published an analysis the

227
00:14:05,200 --> 00:14:08,679
Speaker 1: molars which concluded quote, I believe that Mr. Miller is

228
00:14:08,760 --> 00:14:11,960
Speaker 1: fully justified in holding that the lower molars of the

229
00:14:11,960 --> 00:14:15,480
Speaker 1: pilt down jaw are those of a chimpanzee and not

230
00:14:15,760 --> 00:14:21,080
Speaker 1: of an extinct genus of hominity. As more analysis emerged,

231
00:14:21,200 --> 00:14:23,680
Speaker 1: there were also people who not only questioned whether this

232
00:14:23,720 --> 00:14:28,280
Speaker 1: work was quote scientifically justifiable, but also warned that all

233
00:14:28,320 --> 00:14:33,160
Speaker 1: this buzz and heightened expectations were dangerous. George Grant mcgurdy

234
00:14:33,280 --> 00:14:36,120
Speaker 1: had published a fairly credulous overview of the pilt Down

235
00:14:36,160 --> 00:14:39,840
Speaker 1: findings in nineteen fourteen, but by nineteen sixteen he had

236
00:14:39,840 --> 00:14:43,080
Speaker 1: not only revised his own opinions, but was also alarmed

237
00:14:43,120 --> 00:14:46,320
Speaker 1: at the state of scientific inquiry around the pilt Down Man.

238
00:14:47,040 --> 00:14:51,359
Speaker 1: In the journal Science, mcgourty outlined a range of doubts, criticisms,

239
00:14:51,360 --> 00:14:55,400
Speaker 1: and skeptical inquiries that had come in from the United States, Britain, France,

240
00:14:55,440 --> 00:14:59,040
Speaker 1: and Italy, among other places, and he included this warning quote.

241
00:14:59,560 --> 00:15:04,600
Speaker 1: Has not this dazzling combination blinded the discoverers and indirectly

242
00:15:04,720 --> 00:15:08,240
Speaker 1: some of their colleagues, even at a distance, because of

243
00:15:08,280 --> 00:15:11,760
Speaker 1: the high pitch of expectancy to which recent discoveries in

244
00:15:11,800 --> 00:15:17,560
Speaker 1: the prehistoric field have not, without reason contributed. Under the circumstances,

245
00:15:17,560 --> 00:15:22,880
Speaker 1: such blindness, if only temporary, would be pardonable in comparatively harmless,

246
00:15:22,920 --> 00:15:27,239
Speaker 1: but serious danger lurks in the possibility of its persisting

247
00:15:27,400 --> 00:15:30,640
Speaker 1: long enough to become an obsession and a hindrance to

248
00:15:30,840 --> 00:15:35,240
Speaker 1: future progress in this particular field, and that's exactly what

249
00:15:35,320 --> 00:15:38,840
Speaker 1: was happening. In spite of the growing body of skepticism

250
00:15:38,880 --> 00:15:42,600
Speaker 1: and criticism, the pilt Down man became a widely accepted

251
00:15:42,680 --> 00:15:46,560
Speaker 1: part of a body of scientific literature. Things started to

252
00:15:46,680 --> 00:15:50,560
Speaker 1: unravel a little about a decade after the pilt Down discovery. First,

253
00:15:50,760 --> 00:15:54,080
Speaker 1: in it was discovered that these gravel beds where the

254
00:15:54,120 --> 00:15:57,840
Speaker 1: fossils were found were not old enough to contain five

255
00:15:57,960 --> 00:16:03,960
Speaker 1: hundred thousand year old fossils. Whoops uh. Then, starting in

256
00:16:04,000 --> 00:16:08,600
Speaker 1: the nineteen thirties, paleontologists started finding other hominid fossils in

257
00:16:08,720 --> 00:16:11,440
Speaker 1: other parts of the world, and they seemed to suggest

258
00:16:11,440 --> 00:16:14,560
Speaker 1: an evolution of human life that was taking place primarily

259
00:16:14,600 --> 00:16:17,960
Speaker 1: in Africa and Asia. And as we noted earlier that

260
00:16:18,040 --> 00:16:20,640
Speaker 1: the jaws were becoming more human like before the brain

261
00:16:20,720 --> 00:16:24,640
Speaker 1: cases and not the other way around, it made less

262
00:16:24,640 --> 00:16:27,600
Speaker 1: and less sense that some critical moment in human evolution

263
00:16:27,720 --> 00:16:30,600
Speaker 1: had happened on some tiny islands off the northwest coast

264
00:16:30,600 --> 00:16:33,800
Speaker 1: of Europe, following a totally different pattern from what was

265
00:16:33,840 --> 00:16:38,200
Speaker 1: being discovered elsewhere. But even so, a sizeable chunk of

266
00:16:38,240 --> 00:16:41,320
Speaker 1: the scientific community carried on believing that the pilt Down

267
00:16:41,360 --> 00:16:46,320
Speaker 1: specimens were genuine. A number of chemical and Isotopic dating

268
00:16:46,360 --> 00:16:49,480
Speaker 1: methods started to be developed in the nineteen forties, and

269
00:16:49,480 --> 00:16:53,200
Speaker 1: in nineteen fifty three, Kenneth Oakley, then head of anthropology

270
00:16:53,200 --> 00:16:56,400
Speaker 1: at the British Museum, analyze the pilt Down Man's skull

271
00:16:56,480 --> 00:17:01,280
Speaker 1: fragments through fluorine dating, and the fragments were definitely much

272
00:17:01,320 --> 00:17:04,160
Speaker 1: newer than Dawson and Smith Woodward had said, and they

273
00:17:04,160 --> 00:17:07,320
Speaker 1: were way way too new to be the missing link.

274
00:17:07,880 --> 00:17:11,040
Speaker 1: The first test suggested that it was only fifty thousand

275
00:17:11,160 --> 00:17:15,560
Speaker 1: years old, not ten times that. Following Oakley's discovery, the

276
00:17:15,600 --> 00:17:19,159
Speaker 1: British Museum publicly announced that the pilt Down Man was

277
00:17:19,280 --> 00:17:23,960
Speaker 1: a fraud. And these flooring tests definitely were not perfect.

278
00:17:24,440 --> 00:17:27,240
Speaker 1: They showed that all the skull pieces were the same age,

279
00:17:27,400 --> 00:17:30,640
Speaker 1: whereas later analysis would show that in fact they were not,

280
00:17:31,400 --> 00:17:34,640
Speaker 1: and later on more refined dating methods would also determine

281
00:17:34,680 --> 00:17:37,840
Speaker 1: that the pieces were only about six hundred years old,

282
00:17:38,200 --> 00:17:42,240
Speaker 1: certainly not fifty thousand. But in spite of those shortcomings,

283
00:17:42,280 --> 00:17:44,960
Speaker 1: they were definite proof that the pilt Down Man was

284
00:17:45,080 --> 00:17:49,040
Speaker 1: not a real hominid fossil. Yeah. As our ability to

285
00:17:49,080 --> 00:17:52,639
Speaker 1: test things got better over time because we learned, so

286
00:17:52,760 --> 00:17:55,200
Speaker 1: did our ability to point out just how fake these

287
00:17:55,200 --> 00:18:00,639
Speaker 1: things really were. Further analysis showed the mandible was really

288
00:18:00,720 --> 00:18:05,040
Speaker 1: from a juvenile orangutan, and that all these pieces that

289
00:18:05,160 --> 00:18:10,960
Speaker 1: had been purported to be a person's remains were actually

290
00:18:11,000 --> 00:18:15,000
Speaker 1: meticulously altered to look genuine. They had been stained to

291
00:18:15,040 --> 00:18:17,600
Speaker 1: match the material in the gravel beds, but the stains

292
00:18:17,680 --> 00:18:20,399
Speaker 1: were not made of substances that were local to the area.

293
00:18:21,359 --> 00:18:24,600
Speaker 1: The molars had also been artificially worn down to like

294
00:18:24,840 --> 00:18:28,159
Speaker 1: natural and then other mammal fossils that were found in

295
00:18:28,200 --> 00:18:31,520
Speaker 1: the same area were actual genuine fossils, but they were

296
00:18:31,600 --> 00:18:35,680
Speaker 1: not from species that actually lived in pilt Down. So

297
00:18:35,840 --> 00:18:39,000
Speaker 1: this was not a case of somebody accidentally finding some

298
00:18:39,200 --> 00:18:42,399
Speaker 1: human bones near on a rangutan bone for some reason

299
00:18:42,440 --> 00:18:47,000
Speaker 1: and then drawing of logical but incorrect conclusion. It was

300
00:18:47,080 --> 00:18:51,720
Speaker 1: a deliberate hoax. The good news was, with the pilt

301
00:18:51,760 --> 00:18:53,720
Speaker 1: Down man out of the way, all of the other

302
00:18:53,800 --> 00:18:56,840
Speaker 1: fossil evidence that had been discovered in Africa and Asia

303
00:18:56,880 --> 00:19:00,439
Speaker 1: in the decades since then made a lot more sense.

304
00:19:00,720 --> 00:19:03,760
Speaker 1: There was no longer any lingering question of, well, if

305
00:19:03,840 --> 00:19:06,600
Speaker 1: humanity's origins are in this part of the world and

306
00:19:06,640 --> 00:19:09,679
Speaker 1: evolving this way, traveling in this pattern, what is this

307
00:19:09,760 --> 00:19:13,760
Speaker 1: other fossil doing way over here following a completely different model.

308
00:19:15,680 --> 00:19:18,600
Speaker 1: This was incredibly important in terms of the study of

309
00:19:18,680 --> 00:19:21,800
Speaker 1: human evolution. The pilt Down Man had become such a

310
00:19:21,840 --> 00:19:24,640
Speaker 1: dominant presence in the field that people were using its

311
00:19:24,680 --> 00:19:30,440
Speaker 1: existence to totally disregard legitimate fossil findings that strongly suggested

312
00:19:30,560 --> 00:19:35,440
Speaker 1: human origins in Africa. One of the foundations of scientific

313
00:19:35,520 --> 00:19:38,880
Speaker 1: progress is the ability to reassess your conclusions when you're

314
00:19:38,880 --> 00:19:41,760
Speaker 1: faced with new, compelling evidence. But the pilt Down Man

315
00:19:41,880 --> 00:19:45,840
Speaker 1: was such a juggernaut that people were disregarding that new

316
00:19:45,880 --> 00:19:50,080
Speaker 1: evidence instead. This was probably complicated by a conscious or

317
00:19:50,200 --> 00:19:54,520
Speaker 1: unconscious reluctance among at least some scientists to believe that

318
00:19:54,600 --> 00:19:59,679
Speaker 1: modern humanity rose in Africa, not in Britain. But the

319
00:19:59,680 --> 00:20:02,680
Speaker 1: bad news was that a lot of the world had

320
00:20:02,720 --> 00:20:06,879
Speaker 1: fallen for this hoax. It had impeded progress and perpetuated

321
00:20:06,960 --> 00:20:11,440
Speaker 1: inaccurate information for decades. On top of that, the revelation

322
00:20:11,520 --> 00:20:15,399
Speaker 1: that it wasn't real eroded the general public's belief in science.

323
00:20:16,080 --> 00:20:18,919
Speaker 1: In the words of Ernest A. Houghton of Harvard, writing

324
00:20:18,960 --> 00:20:23,320
Speaker 1: an American Anthropologists in ninety four, quote, what really worries

325
00:20:23,359 --> 00:20:26,040
Speaker 1: me is the revelation to a lady that is often

326
00:20:26,080 --> 00:20:30,359
Speaker 1: hostile to biological science, of calculated dishonesty on the part

327
00:20:30,400 --> 00:20:34,480
Speaker 1: of someone intimately concerned with a discovery of supposedly great

328
00:20:34,520 --> 00:20:38,120
Speaker 1: importance to the history of man. It is as shocking

329
00:20:38,240 --> 00:20:40,199
Speaker 1: is the proof that men in high places of our

330
00:20:40,240 --> 00:20:44,040
Speaker 1: own government have betrayed their country. Already, the press is

331
00:20:44,040 --> 00:20:47,919
Speaker 1: flooded with accusations by anti evolutionists that all of the

332
00:20:47,920 --> 00:20:51,040
Speaker 1: other evidence of man's origin from an ape like ancestry

333
00:20:51,160 --> 00:20:55,320
Speaker 1: has been deliberately faked by unscrupulous scientists. The fact that

334
00:20:55,359 --> 00:20:58,720
Speaker 1: the pilt down fraud is possibly and even probably unique,

335
00:20:58,760 --> 00:21:03,240
Speaker 1: will be very difficult for the public to accept. Before

336
00:21:03,240 --> 00:21:06,200
Speaker 1: you get too attached to the wise words of Ernest here,

337
00:21:07,920 --> 00:21:10,320
Speaker 1: I mean they really touched me. I feel like they

338
00:21:10,320 --> 00:21:14,199
Speaker 1: are applicable even still today. Uh. He also did a

339
00:21:14,200 --> 00:21:18,320
Speaker 1: lot of work combining race in criminology that was influenced

340
00:21:18,320 --> 00:21:21,560
Speaker 1: by the eugenics movement, and the a lot of that

341
00:21:21,600 --> 00:21:25,280
Speaker 1: work was pretty definitely racist. So as much as I

342
00:21:25,320 --> 00:21:28,800
Speaker 1: love these words that he has to say about how

343
00:21:28,880 --> 00:21:31,720
Speaker 1: damaging it was for this to be revealed as a fraud,

344
00:21:33,119 --> 00:21:35,600
Speaker 1: there are other factors of his work. So this is

345
00:21:35,640 --> 00:21:39,600
Speaker 1: not a uh an endorsement of him as a scientist

346
00:21:39,680 --> 00:21:45,400
Speaker 1: by us as podcasters who are not scientists. Uh. Yeah,

347
00:21:45,480 --> 00:21:48,760
Speaker 1: we can appreciate his insight in that moment without applauding

348
00:21:48,800 --> 00:21:51,400
Speaker 1: the rest of his body of work, for sure. Uh.

349
00:21:51,400 --> 00:21:54,879
Speaker 1: And with this finding now unquestionably shown to be fraudulent,

350
00:21:55,400 --> 00:21:58,080
Speaker 1: the focus then turned to piecing together who had done

351
00:21:58,080 --> 00:21:59,879
Speaker 1: it and why, And we're going to talk about that

352
00:22:00,000 --> 00:22:01,919
Speaker 1: after we first paused for a word from one of

353
00:22:01,960 --> 00:22:11,240
Speaker 1: our sponsors. In the years after the Piltdown Man was

354
00:22:11,280 --> 00:22:14,920
Speaker 1: shown to be a hoax, many many theories were put

355
00:22:15,000 --> 00:22:18,760
Speaker 1: forth about the potential culprits. A lot of the attention

356
00:22:18,800 --> 00:22:21,720
Speaker 1: has been on Dawson himself. After all, he was the

357
00:22:21,720 --> 00:22:24,320
Speaker 1: one who reported the findings of the first place, and

358
00:22:24,359 --> 00:22:27,800
Speaker 1: he was instrumental in the announcement and the initial investigations.

359
00:22:28,400 --> 00:22:31,399
Speaker 1: He may have hoped that such a profound discovery would

360
00:22:31,400 --> 00:22:35,320
Speaker 1: earn him admission into the Royal Society. A couple of

361
00:22:35,359 --> 00:22:38,639
Speaker 1: people who either knew or worked with Dawson were siting

362
00:22:38,880 --> 00:22:43,399
Speaker 1: side of his possibilities as well, including Samuel Woodhead and

363
00:22:43,640 --> 00:22:46,959
Speaker 1: Pierre Taliard de Chardins. The latter was the one who

364
00:22:47,000 --> 00:22:51,880
Speaker 1: actually found that canine tooth. Even though he played such

365
00:22:51,880 --> 00:22:54,920
Speaker 1: a huge role, most people did not suspect Sir Arthur

366
00:22:54,920 --> 00:22:57,879
Speaker 1: Smith Woodward, believing him to have been an unwilling dupe

367
00:22:58,320 --> 00:23:01,080
Speaker 1: or one of the intended targets to His reputation would

368
00:23:01,080 --> 00:23:03,359
Speaker 1: have been ruined if word had gotten out while he

369
00:23:03,400 --> 00:23:06,800
Speaker 1: was still alive. Sir Arthur Keith, whose paper on the

370
00:23:06,840 --> 00:23:10,600
Speaker 1: skull reconstruction we talked about earlier, was also suggested as

371
00:23:10,600 --> 00:23:14,400
Speaker 1: a suspect. One of the most famous suspects, at least

372
00:23:14,400 --> 00:23:19,000
Speaker 1: outside of the world of scientists, was Sir Arthur Conan Doyle,

373
00:23:19,320 --> 00:23:21,760
Speaker 1: who knew Dawson had an interest in this type of

374
00:23:21,760 --> 00:23:26,080
Speaker 1: thing and lived nearby. In nine weird set of criteria

375
00:23:26,240 --> 00:23:30,359
Speaker 1: to say somebody is a suspect, I mean there were like,

376
00:23:30,400 --> 00:23:32,200
Speaker 1: apparently there were people who were like, he just wants

377
00:23:32,240 --> 00:23:37,640
Speaker 1: to destroy the evolutionists, right, that's some seriously circumstantial stuff

378
00:23:37,680 --> 00:23:42,440
Speaker 1: that's getting piece together. Flimsy circumstantial stuff. Uh in n s.

379
00:23:42,680 --> 00:23:45,840
Speaker 1: A trunk found in storage in the British Museum was

380
00:23:45,920 --> 00:23:49,240
Speaker 1: discovered to contain a number of bones, including some that

381
00:23:49,320 --> 00:23:52,439
Speaker 1: had been stained in a similar manner to the piltdown Man.

382
00:23:53,119 --> 00:23:56,960
Speaker 1: This trunk marked with the initials M. A. C. H

383
00:23:57,040 --> 00:24:01,080
Speaker 1: apparently belonged to Martin A. C. Hinton, who also amassed

384
00:24:01,160 --> 00:24:04,879
Speaker 1: quite a collection of other bones, fossils, and specimens. He

385
00:24:04,920 --> 00:24:07,159
Speaker 1: had been working as a volunteer at the museum in

386
00:24:07,280 --> 00:24:10,240
Speaker 1: nineteen twelve, and he became its keeper of Zoology in

387
00:24:10,400 --> 00:24:15,000
Speaker 1: nineteen thirty six. So naturally this brought up lots of

388
00:24:15,080 --> 00:24:17,159
Speaker 1: theories about what was going on with what was in

389
00:24:17,160 --> 00:24:19,240
Speaker 1: this trunk. One of the theories was that these bones

390
00:24:19,240 --> 00:24:21,919
Speaker 1: were Hinton's trial run, and that he had done this

391
00:24:21,960 --> 00:24:25,280
Speaker 1: and then planted the fossils in quotation marks to get

392
00:24:25,320 --> 00:24:29,280
Speaker 1: revenge on Smith Woodward, who had turned him down when

393
00:24:29,280 --> 00:24:32,560
Speaker 1: he tried to move his volunteer position back in nineteen

394
00:24:32,560 --> 00:24:36,520
Speaker 1: twelve into a paid one. However, not all of this

395
00:24:36,680 --> 00:24:40,080
Speaker 1: quite adds up. I had a hard time pending down

396
00:24:40,119 --> 00:24:44,919
Speaker 1: exactly why this was later debunked as being who had

397
00:24:45,040 --> 00:24:48,800
Speaker 1: orchestrated this, But his time at the museum started after

398
00:24:49,080 --> 00:24:53,119
Speaker 1: the first discovery at pilt Down, and he also had

399
00:24:54,640 --> 00:24:59,200
Speaker 1: expressed some skepticism at the fine being authentic. So another

400
00:24:59,320 --> 00:25:02,560
Speaker 1: school of ought is that the way these stained bones

401
00:25:02,800 --> 00:25:05,520
Speaker 1: that looked very similar to the pilt Down specimens came

402
00:25:05,520 --> 00:25:08,760
Speaker 1: to be in his suitcase is that he was trying

403
00:25:08,800 --> 00:25:12,080
Speaker 1: to replicate the coloring it pilt down to prove that

404
00:25:12,200 --> 00:25:16,960
Speaker 1: it was a fraud. The paper, published in Royal Society

405
00:25:17,040 --> 00:25:20,960
Speaker 1: Open Science this year, is an attempt to conclusively solve

406
00:25:21,040 --> 00:25:24,520
Speaker 1: this whole puzzle once and for all. The study involved

407
00:25:24,680 --> 00:25:29,960
Speaker 1: DNA analysis, dating analysis, spectroscopy, and high precision measurements of

408
00:25:30,000 --> 00:25:34,160
Speaker 1: the specimens, as well as studying three dimensional representations of them,

409
00:25:34,160 --> 00:25:39,840
Speaker 1: which is known as virtual anthropology. The DNA analysis confirmed

410
00:25:39,920 --> 00:25:43,840
Speaker 1: that teeth and the mandible were from an orangutan, probably

411
00:25:43,880 --> 00:25:47,240
Speaker 1: one born in Borneo, and that all of the orangutan

412
00:25:47,359 --> 00:25:50,560
Speaker 1: specimens that were part of this hoax probably came from

413
00:25:50,600 --> 00:25:54,240
Speaker 1: the same individual animal. Attempts to figure out whether there

414
00:25:54,240 --> 00:25:58,359
Speaker 1: are any missing orangutan specimens and local museum collections have

415
00:25:58,560 --> 00:26:02,120
Speaker 1: so far been unsuccessful, but it's also possible that somebody

416
00:26:02,119 --> 00:26:06,240
Speaker 1: could have bought an orangutan skull in an antiquarian shop.

417
00:26:07,200 --> 00:26:11,440
Speaker 1: A minimum of two, possibly three different human skulls were

418
00:26:11,520 --> 00:26:14,680
Speaker 1: used in the production of the skull fragments, and while

419
00:26:14,760 --> 00:26:17,040
Speaker 1: tests to figure out whether they were all the same

420
00:26:17,080 --> 00:26:20,720
Speaker 1: age were inconclusive, they were all subjected to the same

421
00:26:20,880 --> 00:26:23,280
Speaker 1: m O to make them look like fossils that could

422
00:26:23,320 --> 00:26:28,479
Speaker 1: have come from that gravel bed, and there was dental

423
00:26:28,640 --> 00:26:31,679
Speaker 1: putty used to hold the teeth in place and the

424
00:26:31,680 --> 00:26:34,919
Speaker 1: mandible and to hold the gravel and pebble plugs in place,

425
00:26:35,760 --> 00:26:38,399
Speaker 1: with these materials being similar to the sediment that was

426
00:26:38,400 --> 00:26:41,159
Speaker 1: at the pilt Down dig site, that this discovery of

427
00:26:41,240 --> 00:26:44,879
Speaker 1: dentil putty was not new to this research that was

428
00:26:44,960 --> 00:26:47,680
Speaker 1: just published, like people knew about the dentil putty way before,

429
00:26:48,280 --> 00:26:54,280
Speaker 1: which like continues to make me question why in n

430
00:26:56,000 --> 00:27:02,640
Speaker 1: nobody was like this looks glued on, right. I mean,

431
00:27:02,680 --> 00:27:07,080
Speaker 1: maybe it was just some really really skillful dentil putty use,

432
00:27:07,280 --> 00:27:11,800
Speaker 1: but I don't know. That's one of the many things

433
00:27:11,840 --> 00:27:13,840
Speaker 1: that makes me go, how ready were you all to

434
00:27:13,920 --> 00:27:18,760
Speaker 1: believe that the missing link was from Britain? Because that's

435
00:27:18,800 --> 00:27:20,440
Speaker 1: the only way all this works. And I think the

436
00:27:20,480 --> 00:27:24,960
Speaker 1: answer is very ready, extremely ready. The team concludes that,

437
00:27:25,080 --> 00:27:27,719
Speaker 1: given the consistencies in the m O and the limited

438
00:27:27,800 --> 00:27:30,880
Speaker 1: number of total specimens, the pilt Down Man was probably

439
00:27:30,880 --> 00:27:35,040
Speaker 1: the work of one forger, most likely Charles Dawson, possibly

440
00:27:35,080 --> 00:27:38,560
Speaker 1: trying to further his own scientific career, which given that

441
00:27:38,640 --> 00:27:41,399
Speaker 1: he died in nineteen sixteen, at the age of fifty two,

442
00:27:41,440 --> 00:27:44,560
Speaker 1: just four years after the first announcement clearly did not

443
00:27:44,640 --> 00:27:47,480
Speaker 1: quite work out for him. I had a whole conversation

444
00:27:47,520 --> 00:27:49,960
Speaker 1: about this episode with with my husband in the car

445
00:27:50,040 --> 00:27:54,479
Speaker 1: over the weekend about how, like, you know, a lot

446
00:27:54,520 --> 00:27:57,920
Speaker 1: of these different people have been put forth as potential suspects,

447
00:27:58,119 --> 00:27:59,880
Speaker 1: and a lot of them are are sort of dismissed,

448
00:27:59,880 --> 00:28:03,760
Speaker 1: and really all of these things are really circumstantial, Like

449
00:28:03,800 --> 00:28:07,000
Speaker 1: there's just there's even with all of this analysis, there's

450
00:28:07,000 --> 00:28:09,560
Speaker 1: still a lot of circumstantial evidence and guesswork and stuff

451
00:28:09,600 --> 00:28:12,879
Speaker 1: like that. But to me, the biggest strike against Charles

452
00:28:12,920 --> 00:28:16,240
Speaker 1: Dawson is the fact that he did die only four

453
00:28:16,320 --> 00:28:21,760
Speaker 1: years after this whole thing started, so any like many

454
00:28:21,800 --> 00:28:23,879
Speaker 1: of these other people who have been pointed out as

455
00:28:23,920 --> 00:28:27,359
Speaker 1: suspects lived for a whole lot longer, and and that

456
00:28:27,480 --> 00:28:29,640
Speaker 1: sort of raises the question of, Okay, what were they

457
00:28:29,800 --> 00:28:35,520
Speaker 1: after that never came to fruition? Right, Like Charles Dawson's

458
00:28:35,600 --> 00:28:40,000
Speaker 1: relatively early death makes it seem like whatever he was

459
00:28:40,040 --> 00:28:43,040
Speaker 1: after he didn't get and then he was never he

460
00:28:43,120 --> 00:28:46,719
Speaker 1: wasn't around to either further perpetuate it or be like,

461
00:28:46,760 --> 00:28:50,120
Speaker 1: you know what I made that up like that's it's

462
00:28:50,240 --> 00:28:55,560
Speaker 1: yet another piece of circumstantial evidence, uh in in the

463
00:28:55,640 --> 00:28:59,040
Speaker 1: Charles Dawson column. So all of that, though, may raise

464
00:28:59,080 --> 00:29:03,520
Speaker 1: the question why spend so much time and effort just

465
00:29:03,680 --> 00:29:06,040
Speaker 1: trying to get the bottom of who did this? And so,

466
00:29:06,120 --> 00:29:09,680
Speaker 1: in the words of the papers authors quote, solving the

467
00:29:09,720 --> 00:29:13,240
Speaker 1: pilt down hoax is still important now. It stands as

468
00:29:13,280 --> 00:29:16,200
Speaker 1: a cautionary tale to scientists not to see what they

469
00:29:16,240 --> 00:29:20,000
Speaker 1: want to see, but to remain objective and to subject

470
00:29:20,200 --> 00:29:27,680
Speaker 1: even their own findings to the strongest scientific scrutiny. That's

471
00:29:27,680 --> 00:29:31,200
Speaker 1: a piltdown, man. I love that episode. Thank you, Tracy. Oh,

472
00:29:31,240 --> 00:29:35,280
Speaker 1: you're very welcome. I'm I'm gonna totally admit I had

473
00:29:35,320 --> 00:29:42,840
Speaker 1: a very good time reading the vastly incorrect papers published

474
00:29:43,320 --> 00:29:46,680
Speaker 1: in the early nineteen teens about this finding from people

475
00:29:46,680 --> 00:29:49,400
Speaker 1: who were flat out wrong, and at the same time

476
00:29:49,440 --> 00:29:55,440
Speaker 1: I was really bad about it, Like uh we I

477
00:29:55,520 --> 00:29:58,720
Speaker 1: have often when we've done episodes about old medical history

478
00:29:58,840 --> 00:30:01,640
Speaker 1: or something like that, read you know, the old papers

479
00:30:01,720 --> 00:30:04,680
Speaker 1: from the time that that were published, and these, you know,

480
00:30:05,000 --> 00:30:09,959
Speaker 1: people very confidently espousing stuff that's wrong, just really wrong,

481
00:30:10,360 --> 00:30:12,400
Speaker 1: and that it makes me a lot matter this time

482
00:30:12,440 --> 00:30:15,160
Speaker 1: because it was wrong, and somebody did it on purpose

483
00:30:15,440 --> 00:30:19,600
Speaker 1: and it stood in the way of scientific progress for decades.

484
00:30:20,080 --> 00:30:23,080
Speaker 1: Makes me real mad. Yeah, we uh you and I

485
00:30:23,120 --> 00:30:27,400
Speaker 1: talked about off Mike, the fact that forty years is

486
00:30:27,440 --> 00:30:29,960
Speaker 1: a really long time when you consider like that is

487
00:30:30,000 --> 00:30:32,720
Speaker 1: the length of a career for a scientist in some cases.

488
00:30:32,840 --> 00:30:36,440
Speaker 1: And so there were probably people who were not willingly

489
00:30:36,720 --> 00:30:40,960
Speaker 1: even party to this sort of blindness. But we're proceeding

490
00:30:41,000 --> 00:30:45,760
Speaker 1: along on a career path that was basically complete blunder,

491
00:30:46,120 --> 00:30:50,480
Speaker 1: and they wasted their time and their scientific minds and yeah,

492
00:30:50,600 --> 00:30:55,760
Speaker 1: and wasted the greater whole of humanity's ability to learn

493
00:30:56,320 --> 00:30:59,960
Speaker 1: more about where we came from. And then it's by

494
00:31:00,080 --> 00:31:02,920
Speaker 1: total coincidence that between the day when I wrote this

495
00:31:03,000 --> 00:31:06,640
Speaker 1: on the calendar however many month months ago, and now

496
00:31:07,320 --> 00:31:11,480
Speaker 1: like now, there is such a renewed focus on like

497
00:31:11,760 --> 00:31:17,240
Speaker 1: the the putting out there of just fake wrong information

498
00:31:17,880 --> 00:31:26,480
Speaker 1: that is demonstrably wrong and it being accepted as fact. Ah,

499
00:31:26,520 --> 00:31:29,000
Speaker 1: do you have listener mail? I do, And it's also

500
00:31:29,040 --> 00:31:31,640
Speaker 1: about science. It is from Sarah. Here's what she says.

501
00:31:31,680 --> 00:31:35,000
Speaker 1: Sarah says, Dear Holly and Tracy, longtime listener, first time caller.

502
00:31:35,120 --> 00:31:38,400
Speaker 1: I love your podcast, But yesterday was downright spooky. I'm

503
00:31:38,440 --> 00:31:40,800
Speaker 1: a graduate student at the University of Washington, and I

504
00:31:40,840 --> 00:31:43,800
Speaker 1: was in my dungeon I mean sub basement lab, happily

505
00:31:43,840 --> 00:31:47,080
Speaker 1: listening to my backlog podcasts when your podcast about the

506
00:31:47,160 --> 00:31:50,400
Speaker 1: Orphans tsunami began. The reason this is spooky is that

507
00:31:50,440 --> 00:31:53,040
Speaker 1: I was collecting data about a landslide I think was

508
00:31:53,080 --> 00:31:56,640
Speaker 1: triggered by the earthquake. Right now, I am doing a

509
00:31:56,680 --> 00:31:59,240
Speaker 1: green size analysis of my slide and comparing it to

510
00:31:59,320 --> 00:32:04,520
Speaker 1: the devastated landslide that killed fifty people I have. I

511
00:32:04,600 --> 00:32:07,680
Speaker 1: have attached some pictures of my sieves and oven and

512
00:32:07,800 --> 00:32:10,760
Speaker 1: the field work back ho and my mentor where it

513
00:32:10,840 --> 00:32:14,520
Speaker 1: samples were collected. I continued with my work, which involved

514
00:32:14,560 --> 00:32:17,320
Speaker 1: running some errands well low and Behold, just as I'm

515
00:32:17,320 --> 00:32:20,200
Speaker 1: getting into the car to take my radio carbon samples

516
00:32:20,240 --> 00:32:22,680
Speaker 1: to the lab, you talk about radio carbon dating. I

517
00:32:22,720 --> 00:32:25,880
Speaker 1: would like to respectfully request that you, lovely ladies, please

518
00:32:25,920 --> 00:32:29,920
Speaker 1: remove the cameras you have following me around. This connection

519
00:32:30,000 --> 00:32:32,560
Speaker 1: between landslides and earthquakes makes sense when you think about it.

520
00:32:32,560 --> 00:32:36,200
Speaker 1: The shaking cause by an earthquake can destabilize otherwise safe slopes,

521
00:32:36,600 --> 00:32:40,760
Speaker 1: high topography, can also amp amplify and earthquakes waves, creating

522
00:32:40,760 --> 00:32:45,120
Speaker 1: an even stronger shaking north Widge north Ridge earthquake at

523
00:32:45,120 --> 00:32:47,760
Speaker 1: six point seven on the moment magnitude, we don't use

524
00:32:47,840 --> 00:32:52,960
Speaker 1: rictor anymore cause and estimated fifty thousand uh. It's the earthquakes,

525
00:32:53,000 --> 00:32:55,840
Speaker 1: but I think it might mean landslides. Here in the

526
00:32:55,880 --> 00:33:00,960
Speaker 1: Pacific Northwest, we are especially landslide prone at glaciers occupied

527
00:33:01,080 --> 00:33:05,280
Speaker 1: the area until very recently geologically, and glaciers tend to

528
00:33:05,440 --> 00:33:07,840
Speaker 1: leave very steep slopes because of the immense weight and

529
00:33:07,920 --> 00:33:10,880
Speaker 1: pressure inherent in a mile thick layer of ice. The

530
00:33:10,920 --> 00:33:15,240
Speaker 1: glaciers Impuget Sound especially contribute to our risk and because

531
00:33:15,400 --> 00:33:18,680
Speaker 1: of the large amount of loose sediment deposited, Combining loose

532
00:33:18,680 --> 00:33:21,960
Speaker 1: glacial sediment over steep in slopes and earthquakes could be

533
00:33:22,000 --> 00:33:25,840
Speaker 1: a recipe for disaster. You also mentioned in the episode

534
00:33:26,120 --> 00:33:28,840
Speaker 1: the silt deposits and tide flats that helped us identify

535
00:33:28,880 --> 00:33:31,320
Speaker 1: the tsunami events this summer. I had the good fortune

536
00:33:31,360 --> 00:33:34,000
Speaker 1: to get to examine some of these deposits with one

537
00:33:34,000 --> 00:33:36,400
Speaker 1: of the main authorities I believe he wrote the book

538
00:33:36,400 --> 00:33:38,640
Speaker 1: you mentioned in the podcast. Even with a group of

539
00:33:38,640 --> 00:33:41,920
Speaker 1: twenty trained geologists, and we cut into the tide flat deposits.

540
00:33:41,920 --> 00:33:44,800
Speaker 1: The tiny silt deposits were hard to see. I've attached

541
00:33:44,800 --> 00:33:47,760
Speaker 1: a picture. Then she describes what's in the picture. These

542
00:33:47,800 --> 00:33:50,320
Speaker 1: deposits are only centimeters thick in some places and not

543
00:33:50,400 --> 00:33:53,520
Speaker 1: well distributed. Digging a whole meter away from the original

544
00:33:53,560 --> 00:33:57,120
Speaker 1: had very different thicknesses and layering. The silt, which comes

545
00:33:57,160 --> 00:33:59,240
Speaker 1: from a few kilometers out to see, is carried in

546
00:33:59,360 --> 00:34:02,240
Speaker 1: suspense and by the tsunami wave and deposited inland as

547
00:34:02,280 --> 00:34:04,560
Speaker 1: the wave loses energy. The tide flats are a great

548
00:34:04,560 --> 00:34:06,880
Speaker 1: place to look for this deposit because they are well preserved.

549
00:34:07,360 --> 00:34:11,359
Speaker 1: Storms can create similar deposits as well. I understand if

550
00:34:11,360 --> 00:34:14,960
Speaker 1: you can distinguish storms from tsunammies because storm deposits are thicker,

551
00:34:15,239 --> 00:34:17,480
Speaker 1: because storms into last days. For us, adunamist into the

552
00:34:17,520 --> 00:34:20,239
Speaker 1: last hours. Don't quote me on that, which I just did.

553
00:34:21,520 --> 00:34:23,480
Speaker 1: And then she goes on to write about some uh,

554
00:34:23,719 --> 00:34:26,400
Speaker 1: some territory we've covered in other listener male about the

555
00:34:26,960 --> 00:34:30,880
Speaker 1: um the threat of earthquake in Seattle, and she thanks

556
00:34:30,920 --> 00:34:34,400
Speaker 1: us and gives us some episode suggestions. Thank you so much, Sarah.

557
00:34:34,440 --> 00:34:37,640
Speaker 1: I love when we hear from scientists about our scientific

558
00:34:37,719 --> 00:34:43,040
Speaker 1: episodes with more science information, because that's awesome. Uh. If

559
00:34:43,080 --> 00:34:44,400
Speaker 1: you would like to write to us about this or
