Hello, I'm Dr. Sven string. 00:00:36.46\00:00:38.43 Welcome back to Evolution Impossible. 00:00:38.47\00:00:40.97 Here with me to continue this fascinating 00:00:41.37\00:00:43.61 journey is Dr. John Ashton, 00:00:43.64\00:00:45.37 Ellie Turner, Jeandré Roux, and Stephen Aveling-Rowe. 00:00:45.57\00:00:49.34 Thanks for joining me once again. 00:00:49.38\00:00:51.11 As soon as I say the name, "Darwin," 00:00:51.58\00:00:53.85 I'm sure that you'll instantly know who I'm talking about. 00:00:53.88\00:00:57.59 And pictures of the voyage of the HMS Beagle, 00:00:57.99\00:01:00.66 the Galapagos Islands, finch beaks, 00:01:00.69\00:01:03.16 and that very well known picture of a line-up of monkeys 00:01:03.53\00:01:06.66 slowly standing up and gradually becoming a human being 00:01:06.70\00:01:09.86 will come to mind. 00:01:09.90\00:01:11.33 But sometimes people really don't know 00:01:11.70\00:01:14.30 what Darwin's theory actually was. 00:01:14.34\00:01:16.60 So, John, can you clarify for us, what was Darwin's theory? 00:01:16.74\00:01:21.34 How did he explain how life came about? 00:01:21.38\00:01:24.55 Yeah, sure, well Darwin grew up in the age when we had 00:01:24.98\00:01:29.85 the mechanical world view was being developed, 00:01:29.88\00:01:32.25 and in particular machines were being developed. 00:01:32.29\00:01:36.02 - It was very mechanistic. - Well, yes. 00:01:36.06\00:01:38.03 But machines were evolving. 00:01:38.06\00:01:39.56 And there was talk about these changes, 00:01:39.66\00:01:43.57 and people were actually saying, "Well, did life 00:01:43.60\00:01:46.13 actually change like this too?" 00:01:46.17\00:01:47.67 Because there was also a group of intellectuals 00:01:47.70\00:01:50.64 that believed that the earth was millions of years old. 00:01:50.67\00:01:53.24 So James Hutton back in the late 1700's had proposed this, 00:01:53.27\00:01:58.08 that the biblical timeline was too short, 00:01:58.68\00:02:01.08 that the rocks were millions of years old, 00:02:01.78\00:02:03.45 and that time was much longer. 00:02:03.49\00:02:05.39 Now the other thing was that Darwin, of course, 00:02:05.55\00:02:07.66 was very interested in nature. 00:02:07.69\00:02:09.99 And he'd been interested in breeding, and so forth. 00:02:10.09\00:02:13.53 He was very interested in beetles, if I remember rightly. 00:02:13.63\00:02:15.66 Is that correct? 00:02:15.76\00:02:17.10 Well, that was among the many different types of animals. 00:02:17.23\00:02:20.10 He was interested in lots of animals. 00:02:20.14\00:02:21.50 Part of this initial concept, though, came from 00:02:21.54\00:02:24.61 studying, for example, just grass in the lawn. 00:02:24.77\00:02:27.74 - Watching grass grow. - Well, yes. 00:02:28.04\00:02:30.28 But what he noticed was that when he looked at 00:02:30.31\00:02:33.18 a square yard of grass... 00:02:33.28\00:02:35.02 And they had yards back in those days, 00:02:35.05\00:02:36.92 Meters today. 00:02:37.05\00:02:38.39 ...that there were all these different types 00:02:38.95\00:02:41.49 of grass in there, and they were essentially competing 00:02:41.52\00:02:43.66 for the same space and the same nutrients. 00:02:43.69\00:02:45.99 And this was, in his mind, there was competition here. 00:02:46.43\00:02:51.13 Now at that time, as well, he went on the voyage 00:02:51.43\00:02:54.60 on the Beagle, that we learn about, and he 00:02:54.64\00:02:57.77 was given a copy of the book by Charles Lyell, the geologist. 00:02:57.81\00:03:02.78 Now Lyell, again, was certainly enamored with long ages 00:03:02.81\00:03:07.02 and long periods of time. 00:03:07.18\00:03:09.38 And so, Darwin read this book. 00:03:09.42\00:03:13.22 Now in the meantime, Darwin was putting together 00:03:13.25\00:03:15.69 his ideas of how perhaps mutations produced 00:03:15.96\00:03:21.03 different types of organisms. 00:03:21.06\00:03:22.60 And he drew a tree, a tree of life. 00:03:22.63\00:03:25.50 And he proposed that... 00:03:25.53\00:03:28.34 He saw this piece of grass, and many of them were so similar. 00:03:28.37\00:03:31.77 So he thought, well maybe there are mutations. 00:03:31.81\00:03:34.18 And they breed, and they breed, and then over time 00:03:34.21\00:03:36.28 after enough generations of sufficient differences 00:03:36.48\00:03:39.98 that they actually form a new species. 00:03:40.18\00:03:42.15 So how many generations does it take for that tree 00:03:42.18\00:03:45.12 to start branching? 00:03:45.15\00:03:46.55 Well, Darwin didn't know, of course, but he proposed 00:03:46.76\00:03:49.99 initially in his diagram, and as he wrote about it, 00:03:50.03\00:03:52.49 about a thousand generations. 00:03:52.53\00:03:54.36 But he also made the proposal, well maybe it 00:03:54.40\00:03:56.40 could be ten thousand generations. 00:03:56.43\00:03:58.50 So he didn't really know. 00:03:58.53\00:04:00.20 Which was quite reasonable, you know, 00:04:00.40\00:04:02.57 in terms of developing his theory. 00:04:02.60\00:04:04.74 So essentially, when he read Lyell's book on the journey 00:04:04.84\00:04:09.18 and saw that Lyell had noticed that in the fossil record 00:04:09.21\00:04:13.42 the fossils higher up in the stratum, 00:04:13.45\00:04:16.18 which was the more recent strata, 00:04:16.38\00:04:18.89 seemed to be more complex compared to the animals 00:04:18.92\00:04:21.62 that were further down. 00:04:21.66\00:04:23.02 This sort of matched Darwin's little diagram 00:04:23.32\00:04:26.80 of his tree of mutations. 00:04:26.83\00:04:29.26 And essentially, that's what he did. 00:04:29.46\00:04:30.93 He put the two together. 00:04:30.97\00:04:32.73 And of course, he noticed in that island off the 00:04:33.00\00:04:35.90 west coast of Africa, Madeira, I think it is, 00:04:35.94\00:04:38.21 that there were a couple hundred species of wingless beetles, 00:04:38.24\00:04:41.48 and they had survived, because it's a very windy island. 00:04:41.51\00:04:44.05 And of course, the beetles that have wings 00:04:44.25\00:04:46.08 just got blown off the island. 00:04:46.11\00:04:47.45 So they didn't stay around to mate and breed. 00:04:47.48\00:04:50.59 But the ones that developed deformities, had mutations, 00:04:50.62\00:04:54.29 and so their wings were smaller, they didn't get blown off. 00:04:54.32\00:04:56.76 So they can breed and progress. 00:04:56.79\00:04:58.73 So the beetles were evolving. That's what he was thinking. 00:04:58.76\00:05:00.96 Yes. And so that led to this idea of survival 00:05:01.00\00:05:04.97 of the fittest for the environment. 00:05:05.00\00:05:06.63 So that eliminated the mutations that weren't suited. 00:05:06.67\00:05:11.01 So the best mutations survived. 00:05:11.04\00:05:12.84 So it's a combination of those three factors, really. 00:05:13.07\00:05:15.91 The competition of species, saw them there, 00:05:15.94\00:05:18.71 but there were a lot of similarities with the grass. 00:05:18.75\00:05:20.78 So maybe there was a common ancestor, and they all 00:05:20.82\00:05:23.79 sort of bred and slowly developed differences; 00:05:23.82\00:05:26.05 represented by that little tree. 00:05:26.29\00:05:28.22 And then Lyell's theory; well hang on, we've got all these 00:05:28.32\00:05:31.59 different layers in the rocks, and they contain different 00:05:31.63\00:05:34.36 types of fossils, it would seem, in varying complexity. 00:05:34.40\00:05:38.47 And then this observation of many species competing 00:05:38.60\00:05:42.30 for food, or in the environment, and so forth. 00:05:42.34\00:05:45.21 I mean, it was a brilliant idea he went through. 00:05:45.51\00:05:49.51 One of the things, of course, was he didn't 00:05:49.54\00:05:51.45 know how life started. 00:05:51.48\00:05:53.21 He said, whatever, some primordial ancestry 00:05:53.25\00:05:56.22 into which life was first breathed. 00:05:56.25\00:05:58.25 So that common ancestor going back in time 00:05:58.55\00:06:01.22 through this tree of life. 00:06:01.26\00:06:02.79 That's right, yes. 00:06:02.82\00:06:04.16 And look, this tree of life, it's a brilliant teaching tool. 00:06:04.19\00:06:07.06 You know, in terms of you just draw it out there on a notebook, 00:06:07.10\00:06:10.90 or on a blackboard back then. 00:06:10.93\00:06:13.07 And I guess my question for our panel here is this: 00:06:13.17\00:06:16.04 Does Darwin's tree of life, does it make sense to you? 00:06:16.34\00:06:20.51 Does it, you know, does it kind of explain, 00:06:20.81\00:06:23.75 do you get what Darwin was trying to say? 00:06:24.65\00:06:26.75 Yeah, absolutely. 00:06:27.42\00:06:28.75 I mean, for me, the twigs on the branches, they make sense. 00:06:28.78\00:06:32.12 But the branches and the trunk itself, that's where 00:06:32.55\00:06:35.49 I struggle to see the connections. 00:06:35.69\00:06:37.23 Right, right. 00:06:37.53\00:06:38.86 So you start to doubt the history 00:06:38.89\00:06:41.26 of this very tree of life. 00:06:41.30\00:06:43.47 Seeing the record there, I just haven't seen enough evidence 00:06:43.57\00:06:46.10 for me to personally say that it makes sense. 00:06:46.13\00:06:48.60 Right. And what about you, Jeandré? 00:06:48.64\00:06:50.57 Yeah, yeah, for me it's very vague. 00:06:50.61\00:06:52.17 Like, he draws this tree of life, and he explains it, 00:06:52.21\00:06:58.78 but he doesn't really know anything. 00:06:58.81\00:07:00.15 It could be a thousand years, it could be 00:07:01.02\00:07:03.18 a thousand generations, you know. 00:07:03.22\00:07:04.89 He's just vague. 00:07:05.45\00:07:07.39 And I guess the big question, John, is this: 00:07:07.59\00:07:10.76 Was this the only theory around? 00:07:10.79\00:07:12.79 And Ellie, just wanted to know, did you have any questions 00:07:13.19\00:07:16.46 for John on that topic? 00:07:16.50\00:07:19.13 Yeah, I was specifically wondering what other theories 00:07:19.17\00:07:23.57 in the western world existed in the time of Darwin, 00:07:23.61\00:07:26.44 in terms of the origin of life? 00:07:26.91\00:07:29.24 Obviously there were lots of religions around the world 00:07:29.28\00:07:32.11 that believed different things about how life originated. 00:07:32.15\00:07:35.32 But was it widely believed in Darwin's time that God 00:07:35.48\00:07:38.85 created the world and the things that we see? 00:07:38.89\00:07:41.62 Or was there other theories that were circulating? 00:07:41.66\00:07:44.26 No, certainly in Darwin's time at leading European universities 00:07:44.59\00:07:50.07 most leading scientists and philosophers would have 00:07:51.03\00:07:53.67 believed in God and creation. 00:07:53.70\00:07:56.04 In fact, flood theory to explain the origin of structures 00:07:56.07\00:08:00.88 was probably taught at Oxford University up at least until 00:08:00.91\00:08:04.98 the early 1800's. 00:08:05.01\00:08:07.82 So these scientists certainly believed in that. 00:08:08.62\00:08:11.62 And many of the leading scientists 00:08:11.65\00:08:13.29 were, in fact, creationists. 00:08:13.32\00:08:14.66 You know, people like Newton. 00:08:14.69\00:08:16.49 And even after Darwin's time, there were scientists that 00:08:16.69\00:08:20.36 recognized, hang on, there are major problems with his theory. 00:08:20.60\00:08:23.73 And one of those scientists is James Clerk Maxwell. 00:08:23.77\00:08:26.33 And Maxwell was the physicist that proposed that life was 00:08:26.63\00:08:32.61 a combination of electric and magnetic fields. 00:08:32.64\00:08:35.04 He developed field theory. Brilliant physicist. 00:08:35.08\00:08:37.41 Matter of fact, Einstein simply applied his theories 00:08:37.45\00:08:40.12 to gravity and built on Maxwell. 00:08:40.15\00:08:41.68 So Maxwell is one of the great scientists, 00:08:41.72\00:08:44.45 along with Einstein and Newton. 00:08:44.49\00:08:47.06 And Maxwell is a very strong anti-Darwinist. 00:08:47.26\00:08:50.59 And he would say, "Well, how did molecules evolve?" 00:08:50.63\00:08:53.40 And, "How did atoms evolve?" 00:08:53.43\00:08:55.23 He raised a lot of very interesting questions. 00:08:55.36\00:08:57.87 But in actual fact, the theory of evolution goes back 00:08:58.20\00:09:01.60 to the ancient Greek times. 00:09:01.64\00:09:03.61 So you've got Greek philosophers living about 00:09:03.64\00:09:06.14 500 BC, that sort of era, Democritus, and so forth, 00:09:06.17\00:09:10.05 they believed that, they didn't believe in God; so atheists. 00:09:10.08\00:09:15.48 And so they believed originally that matter, 00:09:15.52\00:09:17.75 there were just all these little particles of matter, 00:09:17.79\00:09:20.12 and they float around and they come together, 00:09:20.16\00:09:23.02 and they became the animals, and the trees, 00:09:23.06\00:09:25.99 and this sort of thing. 00:09:26.03\00:09:27.36 And those theories were recorded, I recall, in a poem 00:09:27.73\00:09:33.03 by Lucretius, a Roman poet. 00:09:33.07\00:09:36.14 He wrote around the first century, I think, 00:09:37.14\00:09:41.01 or there abouts. 00:09:41.04\00:09:42.38 And his poem was essentially lost and rediscovered. 00:09:42.81\00:09:45.78 And again, boy, you're testing me on my history now. 00:09:45.81\00:09:48.88 But I think round about the 1300's a copy of Lucretius' poem 00:09:48.98\00:09:53.39 was discovered that encapsulated these earlier theories 00:09:53.59\00:09:58.69 of Democritus and so forth, in terms of atoms and so forth. 00:09:58.73\00:10:02.93 And that really led to an explosion of thinking 00:10:03.03\00:10:07.60 along these particular lines and laid the foundations later 00:10:07.70\00:10:11.97 for evolutionary theory. 00:10:12.01\00:10:13.34 Of course, in the meantime there had been these theories 00:10:13.38\00:10:15.71 of, you know, that life was spontaneously generated. 00:10:15.74\00:10:19.35 You know, people had noted, well hang on, 00:10:19.65\00:10:21.68 if you leave a bag of wheat out, or something, you know, 00:10:21.72\00:10:24.62 you'd find mice there. 00:10:24.65\00:10:26.45 But Pasteur, again, was able to show that, hang on, 00:10:27.06\00:10:33.13 if you boiled a liquid and sterilized it, 00:10:33.16\00:10:38.67 and separated it from air, you didn't get anything 00:10:38.70\00:10:43.64 coming to life or grow. 00:10:43.67\00:10:45.57 So even today, of course, we still don't know how 00:10:45.84\00:10:49.04 the first life, you know, started. 00:10:49.08\00:10:51.01 Darwin's theory really provided a mechanical 00:10:51.05\00:10:55.28 theory based on a mechanical model. 00:10:55.78\00:10:59.15 Because at that time, Newton had published his 00:10:59.89\00:11:03.06 principle of mechanics and the laws of motion. 00:11:03.26\00:11:07.40 The laws of physics had been discovered. 00:11:07.43\00:11:09.36 But biology was out there by itself. 00:11:09.40\00:11:12.13 So now if you had the tree of life, you had your mutation 00:11:12.53\00:11:15.40 mechanisms, your natural selection. 00:11:15.44\00:11:17.64 You had this mechanical mechanism now 00:11:17.67\00:11:20.08 that could be applied to biology. 00:11:20.28\00:11:23.14 So that's why it really, really took off. 00:11:23.18\00:11:25.21 Plus, Lyell was a brilliant geologist, 00:11:25.25\00:11:28.82 and he did a lot of mapping, he developed this concept 00:11:29.02\00:11:32.35 of the geological column over time. 00:11:32.39\00:11:34.92 And that was embraced too. 00:11:35.22\00:11:37.46 The only issue was that a lot of the measurements 00:11:37.49\00:11:40.20 that he did were based on estimates and so forth 00:11:40.23\00:11:44.80 that we know now are wrong. 00:11:44.90\00:11:46.40 And so, from what I understand, Darwin's grandfather, 00:11:48.27\00:11:50.84 Erasmus Darwin, actually believed in a 00:11:50.87\00:11:54.48 form of evolution as well. 00:11:54.51\00:11:55.84 And he had a colleague, Wallace, if I recall correctly, 00:11:55.88\00:11:59.68 who was also developing these ideas. 00:11:59.71\00:12:01.35 So, there is this real fascination with machines, 00:12:01.38\00:12:04.89 but also this real emphasis on how do we kind of 00:12:04.92\00:12:08.52 eliminate or push these supernatural out of the 00:12:09.32\00:12:14.56 developmental process for life as well. 00:12:14.60\00:12:16.87 So it's very interesting, this whole year in which these 00:12:16.90\00:12:20.94 theories were developing. 00:12:20.97\00:12:22.30 But of course, Darwin had a friend, a colleague, 00:12:22.34\00:12:25.51 Thomas Huxley. 00:12:25.54\00:12:27.04 And can you tell us a little bit more about Thomas Huxley 00:12:27.14\00:12:30.45 and his involvement with Darwin and the promotion 00:12:30.48\00:12:34.55 of the theory of evolution which followed from Darwin's book? 00:12:34.58\00:12:38.72 Yeah, so Huxley wrote a book three or four years after 00:12:38.99\00:12:44.63 Darwin, it would have been published 1864, I think. 00:12:44.66\00:12:48.66 Something like, The Ascent of Man. 00:12:49.46\00:12:52.73 Something like that. 00:12:52.77\00:12:54.10 And essentially, his claim was that man had 00:12:54.14\00:12:58.97 ascended from the apes. 00:12:59.01\00:13:00.38 And so he applied Darwin's theory of evolution, 00:13:00.84\00:13:04.01 particularly in the concept of the origin of man, 00:13:04.11\00:13:07.12 and that man has essentially evolved from apes. 00:13:07.42\00:13:11.52 And that's, of course, why anthropologists and 00:13:11.55\00:13:13.92 paleontologists began looking for the earliest, you know, 00:13:13.96\00:13:18.06 remains of human-like species in Africa. 00:13:18.09\00:13:21.63 That was the whole basis of that because apes 00:13:21.96\00:13:24.33 were found in Africa there. 00:13:24.37\00:13:26.40 So that was a very important aspect. 00:13:27.10\00:13:29.57 And my understanding from the reading of literature is, 00:13:29.77\00:13:32.84 that whole mid-1800 area was so enamored with this 00:13:32.87\00:13:40.22 mechanical view of things. 00:13:40.32\00:13:42.58 And they were certainly talking about, you know, 00:13:42.62\00:13:45.75 in academic circles, machines, and they saw the gradual 00:13:45.79\00:13:50.29 evolution of the steam engine and people with better valves, 00:13:50.33\00:13:54.76 and better safety valves, and you know, so forth, 00:13:54.80\00:13:58.20 develop better machines. 00:13:58.23\00:13:59.57 But at the same time we also, with the industrial revolution, 00:13:59.60\00:14:03.34 saw people moved off their little cottage industries 00:14:03.54\00:14:06.44 into the cities, and there wasn't there enough work now, 00:14:06.47\00:14:09.94 there wasn't enough food, and so there was intense competition 00:14:09.98\00:14:12.98 for survival in the cities to get enough food. 00:14:13.01\00:14:16.12 So there was all this social change that you talked about 00:14:16.15\00:14:20.36 taking place, where you saw that in society. 00:14:20.39\00:14:22.69 People were fighting over the limited resources in the city. 00:14:22.72\00:14:25.96 And at the same time there were all these machines evolving, 00:14:26.26\00:14:28.96 powering the cotton mills, people with better governors 00:14:29.00\00:14:32.73 on their machines, and better horsepower, 00:14:32.77\00:14:34.84 and could produce more. 00:14:34.87\00:14:36.20 And so those factories did better, and the other ones, 00:14:36.91\00:14:39.64 you know, sort of went broke, and this sort of thing. 00:14:39.67\00:14:41.58 So it was a whole environment at that time. 00:14:41.61\00:14:44.41 At the same time, the power of the church was very strong, 00:14:44.51\00:14:48.18 and there were a lot of academics that didn't want 00:14:48.22\00:14:51.19 and were looking for ways to challenge 00:14:51.22\00:14:53.76 the power of the church. 00:14:53.79\00:14:55.29 And Darwin's theory was seen in this way, hang on, 00:14:55.52\00:14:58.23 we can explain the origin of life outside the story 00:14:58.59\00:15:03.87 or the account in Genesis. 00:15:03.97\00:15:05.60 And this had really gripped that group of academics 00:15:06.03\00:15:09.10 that didn't want God in the picture. 00:15:09.27\00:15:11.47 And that would explain the debate between the bishop 00:15:11.67\00:15:14.44 Samuel Wilberforce, Thomas Huxley, 00:15:14.48\00:15:17.35 and also Charles Darwin as well. 00:15:17.38\00:15:19.38 One of the comments they made is, you know, 00:15:19.41\00:15:22.42 whether they evolved from a monkey or an ape. 00:15:22.45\00:15:26.09 You know, whether their grandmother was an ape or not. 00:15:26.12\00:15:29.12 And I guess the question for us today is this: 00:15:29.22\00:15:31.83 How do you feel about this concept of us evolving 00:15:31.86\00:15:35.93 from some kind of ape-like creature in the past? 00:15:35.96\00:15:39.13 How does that strike you? 00:15:39.23\00:15:40.57 I've always struggled with the idea that my 00:15:41.47\00:15:43.34 great great great grandfather was a monkey. 00:15:43.37\00:15:45.51 But I actually had a specific question for Dr. Ashton on that. 00:15:46.37\00:15:49.54 In chapter two of your book you mentioned the find of a skeleton 00:15:50.31\00:15:55.35 that they call, Lucy. 00:15:55.38\00:15:56.82 And that was suppose to be a transitional fossil 00:15:57.39\00:15:59.42 between humans and apes. 00:15:59.45\00:16:00.96 And you noted that since then, there has been more recent 00:16:01.32\00:16:05.63 finds that Lucy was actually more different 00:16:05.66\00:16:08.56 from humans and apes than humans and apes are from each other. 00:16:08.60\00:16:12.10 And I was also wondering what that find exactly was based on. 00:16:13.13\00:16:17.01 Was it based on the skeleton structure, or was it based on 00:16:17.04\00:16:21.14 DNA evidence, or how did they come to that conclusion? 00:16:21.18\00:16:24.41 Yeah, so it's certainly based on anatomical evidence. 00:16:24.51\00:16:27.45 So it was based on the physical bone structure and so forth 00:16:27.85\00:16:31.89 when that was examined. 00:16:31.92\00:16:33.25 It's interesting, in museums that sometimes have models 00:16:33.29\00:16:36.99 of Lucy, and one of the ones that I saw would have been like 00:16:37.19\00:16:42.90 a typical human model where they put hair all over her 00:16:42.93\00:16:47.30 and put sort of an ape-like face. 00:16:47.54\00:16:49.60 But humans stand very different to apes. 00:16:49.64\00:16:54.44 We have a very different pelvic structure, 00:16:54.48\00:16:56.31 the way the bones enter there, and so forth. 00:16:56.34\00:17:00.18 And it's very different. 00:17:00.22\00:17:02.42 And so what happens is, sometimes in these museums 00:17:02.45\00:17:06.92 and in these reconstructions that are portrayed in books, 00:17:06.96\00:17:10.43 they're portrayed it would seem more human-like 00:17:10.63\00:17:13.26 than in actual fact they are, if we actually portrayed them 00:17:13.29\00:17:16.80 as they are correctly anatomically. 00:17:16.83\00:17:19.07 They wouldn't look as human-like as they're portrayed. 00:17:19.27\00:17:22.24 And of course, this all helps confirm this concept 00:17:22.27\00:17:26.17 that we did evolve from apes. 00:17:26.21\00:17:27.54 Where in actual fact, when we look at the actual physiology, 00:17:27.58\00:17:30.18 when we examine the bones, when we examine how they 00:17:30.21\00:17:32.71 would have stood, it would have been very different to those 00:17:32.75\00:17:34.78 images that are created. 00:17:34.82\00:17:36.79 So carry on from that then. 00:17:37.42\00:17:38.89 Think of living fossils. 00:17:38.99\00:17:40.49 I mean, how, within evolutionary millions of years, 00:17:40.69\00:17:44.53 would we still have fossilized remains of things like, I mean, 00:17:44.73\00:17:48.23 there whales, there's so many different species 00:17:48.26\00:17:50.53 that we have exact conformity to what we see 00:17:50.63\00:17:53.47 in the natural world today, and yet, if we look back 00:17:53.50\00:17:56.54 you know, there are also fossil records? 00:17:56.74\00:17:58.84 How does that fit in with the evolutionary perspective? 00:17:58.94\00:18:01.44 Well, of course, yes, Darwin claimed that, you know, we would 00:18:01.94\00:18:06.25 find the fossils of the intermediate species. 00:18:06.28\00:18:08.45 This was a major problem. 00:18:08.48\00:18:10.52 And so, what we find in the fossil record is that 00:18:10.55\00:18:13.29 the species essentially don't change. 00:18:13.52\00:18:15.26 They appear, they stay the same, and then they become extinct, 00:18:15.29\00:18:19.16 or we find fossils like, you say, of whales 00:18:19.19\00:18:21.60 and they're the same today. 00:18:21.63\00:18:22.96 What we're not finding is the intermediate. 00:18:24.17\00:18:26.53 So we should have seen slowly, say, the development of turtles. 00:18:26.57\00:18:30.41 We should have seen slowly a creature changing into a turtle. 00:18:30.44\00:18:34.31 Or the development of horns, 00:18:34.34\00:18:36.38 say, you know, on different species, 00:18:37.05\00:18:39.38 whether it's dinosaurs, where we should have seen the 00:18:39.41\00:18:42.05 gradual development of these. 00:18:42.08\00:18:43.75 But we don't. 00:18:43.79\00:18:45.12 We don't find these evolutionary intermediates. 00:18:45.15\00:18:48.46 You know, a classic one is sort of from dinosaurs to birds, 00:18:48.49\00:18:51.96 looking for the intermediates, they're often desperate 00:18:52.16\00:18:54.66 to find a fossil. 00:18:54.70\00:18:57.20 But the point is that if Darwin's theory really happened, 00:18:57.37\00:19:00.40 and we find trillions of fossils just about, 00:19:00.44\00:19:02.94 there should also be millions of intermediate fossils. 00:19:03.54\00:19:10.65 Millions of fossils showing this gradual transition. 00:19:10.68\00:19:14.35 But we don't find those changes. 00:19:14.72\00:19:16.28 This is a major, major problem. 00:19:16.32\00:19:18.85 And leading paleontologists recognize this too, 00:19:18.89\00:19:21.59 that the geologic column doesn't actually show 00:19:21.62\00:19:25.59 the gradual progression that originally 00:19:25.63\00:19:28.30 Lyell thought that it did. 00:19:28.33\00:19:29.73 And secondly... 00:19:29.83\00:19:31.17 In actual fact, the fossils are all mixed up. 00:19:31.20\00:19:33.44 Like, for example, when I was in Hawaii recently 00:19:33.50\00:19:35.67 I saw in the museum there a fossil of a mammal 00:19:35.70\00:19:40.01 with the remains of a dinosaur in its stomach. 00:19:40.31\00:19:43.75 Well, people often think, you know, the mammals came later, 00:19:44.35\00:19:46.72 but no, they coexisted with dinosaurs. 00:19:46.75\00:19:48.42 Now that's not the picture that we often get. 00:19:48.45\00:19:50.95 No, the fossils, in actual fact, are a lot more mixed up 00:19:51.19\00:19:54.22 than they'd have us to believe in the geological column, 00:19:54.26\00:19:56.93 in actual fact, out there. 00:19:57.26\00:19:58.79 And the other thing is, the lack of these intermediates. 00:19:58.83\00:20:02.36 We haven't found the intermediate fossils. 00:20:02.63\00:20:04.60 So the geologic record, the paleontologic record 00:20:04.63\00:20:09.14 doesn't actually provide evidence for evolution. 00:20:09.17\00:20:12.41 And this is a major problem. 00:20:12.67\00:20:14.18 But again, this isn't really enforced to the young people. 00:20:14.21\00:20:18.78 You know, Dr. Ashton, for me it's always been, 00:20:19.71\00:20:22.25 if evolution teaches that we evolved from apes, 00:20:23.08\00:20:26.19 why are there still apes? 00:20:26.69\00:20:28.02 So how does evolution explain that? 00:20:28.06\00:20:29.79 Well, I guess from the tree they would say 00:20:29.99\00:20:32.39 some continue the same, but you have these mutations 00:20:32.43\00:20:35.50 that come off, and they've accumulated, and so forth. 00:20:35.53\00:20:40.17 But another question that follows from that is, 00:20:40.20\00:20:42.44 it's well known that human beings, chimpanzees, apes, 00:20:42.47\00:20:47.48 we're about 96% the same, in terms of our genome. 00:20:47.58\00:20:51.38 That sounds really suspiciously like the fact that we evolved. 00:20:52.01\00:20:56.62 How would we address that, 00:20:56.65\00:20:59.15 that sort of genetic piece of information? 00:20:59.19\00:21:02.22 Yeah, sure. 00:21:02.42\00:21:03.76 Okay, well look, that's pretty subjective. 00:21:03.79\00:21:05.99 That 96%, I guess, looks at the number of genes that are 00:21:06.03\00:21:12.37 responsible for biochemical pathways that we have. 00:21:12.40\00:21:14.87 So, we are very complex. 00:21:14.90\00:21:16.60 Our biochemistry is extremely complex. 00:21:16.64\00:21:19.21 And so, we have a lot of DNA in us to provide 00:21:19.44\00:21:23.45 those biochemical pathways and all those molecular machines 00:21:23.48\00:21:26.15 that are very similar in a lot of mammals, 00:21:26.18\00:21:27.98 and particularly in apes that are slightly similar to us. 00:21:28.02\00:21:32.39 But that kind of similarity doesn't include a lot of the 00:21:32.65\00:21:35.36 junk DNA which they didn't know. 00:21:35.39\00:21:37.03 So there's a lot of questions over that. 00:21:37.06\00:21:38.59 And when you actually look at the code, 00:21:38.69\00:21:40.30 when I look at the code and read it, 00:21:40.33\00:21:42.93 man, it doesn't look similar to me. 00:21:43.13\00:21:44.47 It doesn't look like 96% similarity. 00:21:44.50\00:21:46.43 It looks totally different. 00:21:46.47\00:21:48.37 What they're saying is that there are sections of code that 00:21:48.40\00:21:50.54 switch on similar genes, and so forth. 00:21:50.57\00:21:55.41 But again, to me, if we use the example of Porsche and VW cars, 00:21:56.18\00:22:02.05 you know, they have the same designer. 00:22:02.08\00:22:03.65 They're quite different. 00:22:03.69\00:22:05.12 But they have a lot of commonality, 00:22:05.85\00:22:07.42 you know, common properties. 00:22:07.46\00:22:08.79 You know, horizontally opposed engines 00:22:08.82\00:22:10.16 and rear engines, and so forth, 00:22:10.19\00:22:12.23 because they have the same designer, father and son team. 00:22:12.26\00:22:14.96 So what you're saying is, similarities in terms of anatomy 00:22:15.16\00:22:18.63 and genetics, and the genome, could also be explained by the 00:22:18.67\00:22:22.57 common designer rather than just a common ancestor. 00:22:22.60\00:22:25.24 - That's the designer reasoning. - Ah yes, yes. 00:22:25.57\00:22:28.14 And look, one of the fascinating things is that 00:22:28.34\00:22:30.65 Darwin's tree and the original evolutionary trees 00:22:30.85\00:22:34.92 that were proposed after Darwin based on the fossil record, 00:22:34.95\00:22:39.39 and the geologic column, and the shape of animals, 00:22:39.42\00:22:44.43 their anatomy and physiology, which we call the 00:22:44.46\00:22:47.23 homologous series, of sort, 00:22:47.26\00:22:49.53 that's based on their anatomy and physiology. 00:22:49.63\00:22:51.57 When we started analyzing the DNA, when we got that 00:22:51.87\00:22:55.00 capability, we found, whoa, hang on, 00:22:55.04\00:22:57.17 it's a totally different picture. 00:22:57.41\00:22:59.27 And so when we drew the, what we call, phylogenetic trees, now 00:22:59.87\00:23:03.58 based on the similarities in DNA, they go really wild. 00:23:03.61\00:23:07.95 Like, I think the ones for humans, we're related to dogs, 00:23:07.98\00:23:11.52 and fungi, and E. coli. 00:23:11.99\00:23:15.56 You know, I mean, it just goes really weird. 00:23:15.99\00:23:21.43 And I think one of the things that people don't realize is 00:23:21.46\00:23:23.57 that the same piece of code in a different environment 00:23:23.60\00:23:27.94 will produce different outcomes. 00:23:27.97\00:23:29.90 And this is one of the fascinating things. 00:23:30.57\00:23:32.31 So you can have a code that might produce an eye 00:23:32.34\00:23:34.21 in one organism, and in another organism 00:23:34.24\00:23:37.35 it doesn't produce an eye. 00:23:37.71\00:23:39.18 This is one of the fascinating things. 00:23:39.51\00:23:42.02 And one of the diagrams that you probably would have seen 00:23:42.22\00:23:44.75 in your science textbooks would have been 00:23:44.79\00:23:47.76 this series of embryos. 00:23:47.79\00:23:50.16 So not only the similarities between chimpanzees 00:23:50.26\00:23:53.50 and apes and human beings, but also embryos. 00:23:53.53\00:23:56.97 Following the development, and you start to see, hang on, 00:23:57.00\00:24:00.50 it looks like evolution. 00:24:00.54\00:24:02.20 You can watch evolution in action. 00:24:02.24\00:24:03.91 So I just wanted to know, do you have any sort of thoughts 00:24:04.11\00:24:07.14 or comments or questions on that aspect of evolution? 00:24:07.18\00:24:10.81 Jumping in on that one, I mean, you know, 00:24:11.41\00:24:13.48 Haeckel's drawing that we see was done quite a while ago. 00:24:13.52\00:24:16.85 You know, it's still being in textbooks right into the 2000's. 00:24:17.72\00:24:21.52 What is the evidence to support that? 00:24:22.39\00:24:24.23 And have there been further photographic studies 00:24:24.26\00:24:26.90 done to document that? 00:24:26.93\00:24:28.66 Yes, yes, certainly. 00:24:29.30\00:24:30.70 So, yes, Haeckel, the German embryologist, proposed that, 00:24:30.73\00:24:35.77 that the embryos went through stages that represented 00:24:35.80\00:24:38.84 the evolutionary ancestor of the species. 00:24:38.87\00:24:42.64 And this has certainly been in textbooks, you know, 00:24:43.45\00:24:47.55 up until fairly recently, as you say, in the mid-2000's. 00:24:47.58\00:24:50.82 I remember seeing that purported or written up in a 00:24:50.85\00:24:53.92 textbook at a university in the university library. 00:24:53.96\00:24:56.59 Which I thought was really wrong, because 00:24:56.62\00:24:58.29 back in the mid-1990's Dr. Richardson 00:24:58.49\00:25:02.20 with a team of colleagues did a major study photographing 00:25:02.40\00:25:05.47 embryos from a number of different creatures 00:25:05.50\00:25:07.20 and putting them together. 00:25:07.24\00:25:08.57 And that was published in, Science, in 1998. 00:25:08.60\00:25:11.01 It was published in, The Journal of Embryology, I think, earlier, 00:25:11.04\00:25:13.88 but it got into, Science. 00:25:13.91\00:25:15.84 The journal, Science, is one of the top science journals 00:25:15.88\00:25:18.71 in the world, with, Nature; so if you get published 00:25:18.75\00:25:21.08 in that journal, you get a lot of brownie points. 00:25:21.12\00:25:22.95 So that has definitely been shown to be incorrect now. 00:25:23.15\00:25:28.42 He showed that that does not occur. 00:25:28.46\00:25:30.36 No human fetus' have gills at any stage. 00:25:30.46\00:25:34.90 None of these scenarios claimed by Haeckel actually occur. 00:25:35.20\00:25:40.24 And really, it's morally wrong that those textbooks 00:25:40.27\00:25:43.81 that should really be up-to-date are publishing that now. 00:25:43.84\00:25:46.27 Because that was a major study to investigate that. 00:25:46.31\00:25:49.58 There were multiple authors. 00:25:49.74\00:25:51.08 It was published in major science journals in 1997, 1998. 00:25:51.11\00:25:55.05 And Dr. Ashton, it sounds like such an emotive story, 00:25:55.42\00:25:58.59 and it's so convincing on the surface, but I'm thinking, 00:25:58.62\00:26:02.56 I'm wondering, am I correct in understanding that 00:26:02.59\00:26:04.76 if our DNA is fully human right from conception, 00:26:04.99\00:26:09.23 that it wouldn't be scientific anyway for us to reflect all the 00:26:09.43\00:26:14.70 different evolutionary stages of the past? 00:26:14.74\00:26:16.97 - Is that correct? - Yes, spot on. 00:26:17.01\00:26:18.91 And that's a very interesting characteristic. 00:26:19.11\00:26:23.04 But what makes our DNA fully human is the big picture 00:26:23.08\00:26:26.55 of the DNA. 00:26:26.58\00:26:27.92 And I guess, what upsets me is that today authors are producing 00:26:27.98\00:26:33.46 books for young children. 00:26:33.49\00:26:35.32 I saw one titled recently, I think, Grandmother Fish. 00:26:35.62\00:26:38.66 Something like that. 00:26:38.69\00:26:40.03 And it's teaching young children that they evolved from fish. 00:26:40.06\00:26:44.60 And I think this is just so morally wrong. 00:26:44.63\00:26:46.90 We don't have any mechanism for that, 00:26:46.94\00:26:48.94 we don't have any geological or paleontological 00:26:48.97\00:26:52.14 evidence for that, and yet this is being put into young minds. 00:26:52.17\00:26:54.98 And that really upsets me. 00:26:55.01\00:26:57.05 You know, we really appreciate you just being able to journey 00:26:57.65\00:27:00.72 with us through Darwin's theory to have a better understanding; 00:27:00.75\00:27:03.99 to understand some of the sociological, but also the 00:27:04.02\00:27:06.52 scientific aspects as well. 00:27:06.55\00:27:08.59 And you know, you might have been thinking you wish 00:27:08.82\00:27:11.19 you were here with us to have this discussion together. 00:27:11.23\00:27:14.20 Well, the good news is this, you can actually join us. 00:27:14.23\00:27:17.33 Just go to any online book store right around the world 00:27:17.80\00:27:21.64 and get Dr. John Ashton's book, Evolution Impossible. 00:27:21.80\00:27:25.54 You can go chapter by chapter. 00:27:25.57\00:27:26.98 You can be one step ahead of us. 00:27:27.01\00:27:28.58 Wouldn't that be great? 00:27:28.61\00:27:29.94 But, you know, it's been really good to gain a very 00:27:29.98\00:27:31.85 clear understanding of what Darwin's theory 00:27:31.88\00:27:34.82 of evolution actually was. 00:27:34.85\00:27:36.79 Now that we have a much better grasp of his theory, 00:27:37.19\00:27:40.62 we can start asking the question, 00:27:40.72\00:27:42.22 is evolution impossible, or is it possible? 00:27:42.26\00:27:45.16 Next time we'll be diving into the smallest living thing; 00:27:45.29\00:27:48.43 the living cell. 00:27:48.46\00:27:49.80 Join us on this exciting journey of scientific discovery. 00:27:49.83\00:27:52.60
