Answers ## Questions about this video What is the main argument of the video regarding the fossil record and human evolution? The video argues that the fossil record does not provide a clear, continuous evolutionary chain from ape-like ancestors to humans, highlighting significant gaps and unresolved issues. What are australopithecines and what role do they play in human evolution according to the video? Australopithecines are a group of small, ape-like hominids thought to be early bipeds and intermediate forms between early hominins and the genus Homo, but the video questions their direct ancestral link to humans. How does the video describe the appearance of the genus Homo in the fossil record? The genus Homo appears abruptly around 2 to 2.5 million years ago in the fossil record, showing human-like features without clear evolutionary precursors. ## Full Transcript — Download SRT & Markdown 00:00 Speaker A About a year ago, I returned from South Africa where I had lived for the previous four and a half years doing a PhD in geology at the University of Johannesburg. While I lived in South Africa, I had many opportunities to learn about some of the famous hominid fossils that were found at the Cradle of Humankind. The Cradle of Humankind is perhaps one of the most famous fossil sites in the world. It's located about an hour north of Johannesburg. Um, what you see in this picture is the Maropeng Museum, which is arguably the best hominid fossil museum in the world. I had many opportunities to go there and learn more about these famous hominid fossils. Um, these are some photos from a tour that I took of the Sterkfontein hominid fossil site where some famous fossils, Mrs. Ples and Littlefoot, were found. Um, it also shows the famous workshop of Dr. Robert Broom, the South African medical doctor who basically founded the field of paleoanthropology in South Africa. And these are wonderful places to go and learn more about these ancient fossils. Um, I also had the opportunity to assist with sampling at a hominid fossil site at the Cradle of Humankind. Um, this is from Bolt's Farm, which is a site where they find many large carnivores and big cats. In fact, some of the fossils that are shown there in the cave wall next to me are actually jaws of big cats. And I had the opportunity to use the paleomagnetism I was studying to go and help with some fossil sampling at Bolt's Farm with some scientists that were trying to do dating of those fossils. So, let's jump into this talk and where we're going to go. We're going to start by talking about the evolutionary view of human origins. What is the evolutionary scheme of how humans originated and evolved from ape-like precursors in the fossil record? We're then going to look at the field of paleoanthropology and how it is fragmented in multiple senses. Paleoanthropology is, of course, the field that studies the origin of humans by looking at fossils in the record. We're then going to look at some of the early hominins, supposedly some of the fossils that represent the earliest members of our lineage that branched out from the line that led to apes around 5 to 8 million years ago. We'll then look at the australopithecines, a very well-known group of hominids that are known for many fossils throughout Africa. We're then going to see if there are intermediate links that supposedly link these ape-like australopithecines to the human-like members of our genus, which is the genus Homo. We'll also then talk about the origin of our genus Homo in the fossil record and how it appears abruptly in the fossil record without any direct evolutionary precursors. We're then going to talk about human exceptionalism. What is it and what does it say about the unique origins of human beings? And finally, we'll talk about our genus Homo that we're a part of and how the major members of the genus Homo are very similar and do not show that we evolved from ape-like ancestors. So, what is the evolutionary view of human origins? Well, a few years ago, I had the opportunity to testify and observe a debate at the Texas State Board of Education where they were discussing how they were going to teach evolution in public schools in Texas. Various experts were invited to come and testify. Some were saying that students should learn the scientific strengths and weaknesses of evolution, and others were saying that we should teach only the evidence for evolution in the classroom. One of the scientists that was brought in and testified that we should teach only the evidence for evolution was an anthropology professor at Southern Methodist University named Ronald Weatherington. Ronald Weatherington that day testified before the Texas State Board of Education about human origins, and he said that human evolution has arguably the most complete sequence of any fossil succession of any mammal in the world. No gaps, no lack of transitional fossils. And he went on to say that human origins provides a nice clean example of what Darwin thought was a gradualistic evolutionary change. As I said, I also had the opportunity to testify before the Texas State Board during this debate. But as I was sitting there listening to Professor Weatherington testify, I thought, "Okay, well, I'm sure he believes what he's saying. I'm sure that he said everything he said in good faith. I have no reason to doubt that. But I know that when you dig into the technical literature, you find that a very different story is being told, that many scientific papers in the technical literature have admitted that there is a severe gap between human-like fossils in the fossil record and our supposed ape-like ancestors." And so when Professor Weatherington said that there is sort of this nice gradual evolutionary chain of fossils, that really is not true when you understand what the technical literature is saying. And so what I really appreciated this day is that there's often sort of one version of the evolutionary story that's told to the public, whether we're talking about National Geographic documentaries or in the news media or when we testify before the state boards of education about what students should learn in schools. And they often put forth sort of this very simplified, dumbed-down version of evolutionary history, saying that we've got it all figured out. There's no weaknesses in our model, and everything we find supports an evolutionary viewpoint. But when you dig into the technical literature, and I knew this because I'd read so many scientific papers in the scientific literature on hominid fossils, when you dig into that technical literature, you find many admissions of large-scale gaps and problems with this evolutionary scheme. And so I want to talk to you today about what some of these evolutionary papers are saying and how they acknowledge that there actually are problems with this overall evolutionary story. So, what is this evolutionary story? Well, it starts between 5 to 8 million years ago with what we call the early hominins. And these are some of the first species that supposedly started to walk upright or they were bipedal, as we would say. And they branched off from the lineage that led to chimpanzees and started a new lineage that led to humans. Then from about two to four and a half million years ago, we have a group called the australopithecines. These are a group of very small, maybe chimp-sized, ape-like creatures which supposedly are some of the first to clearly walk upright. And again, these are sort of supposed to be intermediate between these early hominins and then later hominids like our genus Homo. And in fact, the australopithecines are supposed to be directly ancestral to our genus Homo. And the genus Homo appears around 2 to 2 and a half million years ago in the fossil record. And it is very human-like when it appears. Many of its species, such as Homo erectus, Neanderthals, are very similar to our own species, Homo sapiens. And so the standard hominin phylogeny, when we look at these bones, when we see these diagrams, these evolutionary trees in textbooks, they will connect all these fossils as if one species is ancestral to another. But what does the evidence really say? And is there good evidence that human beings evolved from ape-like creatures? Well, I would say that what we find in the fossil record and what we're going to see in this talk today is that hominid fossils generally fit into two categories: ape-like species and human-like species, with a large unbridged gap between them, and the fossil record does not clearly document the evolution of humans from ape-like precursors. Now, I want to briefly touch upon a terminological issue, and that is what is a hominin or a hominid? These terms are used differently even within the mainstream scientific literature. 00:11 Speaker A learn about some of the famous homminid fossils that were found at the Cradle of Humankind. The Cradle of Humankind is perhaps one of the most famous fossil sites in the world. It's located about an hour north of Johannesburg. Um what 00:24 Speaker A you see in this picture is the Maropang Museum which is arguably the best homminid fossil museum in the world. I had many opportunities to go there and learn more about uh these famous homminid fossils. Um these are some 00:36 Speaker A photos from a tour that I took of the Sturk Fontine homminid fossil site where some famous fossils Mrs. Ples and Littlefoot were found. Um it also shows the famous workshop of Dr. Robert Broom, the South African medical doctor who 00:50 Speaker A basically founded the field of paleoanthropology in South Africa. And these are wonderful places to go and learn more about these ancient fossils. Um, I also have the opportunity to assist with sampling at a homminid fossil site at the cradle of 01:04 Speaker A humankind. Um, this is uh from Bolt Farm, which is a a site where they find many large carnivores and big cats. In fact, some of the fossils that are shown there in the cave wall next to me uh are 01:16 Speaker A actually jaws of big cats. And I had the opportunity to use the paleomagnetism I was studying to go and help with some uh fossil sampling at Bolts Farm with some scientists that were trying to uh do uh dating of those fossils. So, let's jump 01:30 Speaker A into this talk and where we're going to go. We're going to start by talking about the evolutionary view of human origins. what is the evolutionary scheme of how humans originated um and evolved from ape-like precursors in the fossil 01:43 Speaker A record. We're then going to look at the field of paleo anthropology and how it is fragmented in multiple senses. Uh paleo anthropologies is of course the field that studies the origin of humans by looking at fossils in the record. 01:56 Speaker A We're then going to look at some of the early hominins, uh, supposedly some of the fossils that represent, um, the earliest members of our lineage that branched out from the line that led to apes, um, around 5 to 8 million years 02:08 Speaker A ago. We'll then look at the oraliththesines, a very well-known group of hominids uh, that are known for many fossils throughout Africa. We're then going to see if there are intermediate links that supposedly link these ape-ike oropithesines to the human-like members 02:22 Speaker A of our genus, which is the genus Homo. We'll also then talk about the origin of our genus homo in the fossil record and how it appears abruptly in the fossil record without any direct evolutionary precursors. Um we're then going to talk 02:35 Speaker A about human exceptionalism. What is it and what does it say about the unique origins of human beings? And finally, we'll talk about our genus Homo that we're a part of and how the major members of the genus Homo are very 02:46 Speaker A similar and do not show that we evolved from apeike ancestors. So what is the evolutionary view of human origins? 02:53 Speaker A Well, a few years ago, I had the opportunity to testify and and uh observe a debate at the Texas State Board of Education where they were discussing how they were going to teach evolution in public schools in Texas.

One of the scientists that 03:21 Speaker A was brought in and and testified that we should teach only the evidence for evolution was an anthropology professor at Southern Methodist University named Ronald Weatherington. Um Ronald Weatherton that day testified before the Texas State Board of Education about 03:36 Speaker A human origins and he said that human evolution has arguably the most complete sequence of any fossil succession of any mammal in the world. No gaps, no lack of transitional fossils. And he went on to say that human origins provides a nice 03:51 Speaker A clean example of what Darwin thought was a gradualistic evolutionary change.

I'm sure that he said everything he said in good faith. I have no reason to doubt that.

And so when Professor Weatherington said that there is sort of 04:31 Speaker A this nice gradual evolutionary chain of fossils, that that really is not true when you understand what the technical literature is saying.

So what is this evolutionary story? Well, it starts between 5 to 8 million years ago with what we call the early hominins. And these are some of the first species that supposedly started to walk upright or they were 05:46 Speaker A bipedal as we would say. And they branched off from the lineage that led to chimpanzees and started a new lineage that led to humans. Um then from about two to four and a half million years ago we have a group called the 05:58 Speaker A orolopithesines. These are a group of very small maybe chimpsized um ape-like creatures which supposedly are some of the first to clearly walk upright. And again these are sort of supposed to be intermediate between these early hominins and then later hominids like 06:13 Speaker A our genus Homo. And in fact the oral epiptheian scenes are supposed to be directly ancestral to our genus Homo. 06:20 Speaker A And the genus Homo appears around 2 to 2 and a half million years ago in the fossil record. And it is very humanlike when it appears. Uh many of its species such as Homoctus, Neanderthalss are very similar to our own species, Homo 06:33 Speaker A sapiens. And so the standard hominin fogyny when we look at these bones, we you know when we see these diagrams, these evolutionary trees and textbooks, they will connect all these fossils as if one species is ancestral to another. 06:47 Speaker A But what does the evidence really say? And is there good evidence that human beings evolved from ape-like creatures? 06:53 Speaker A Well, I would say that what we're what we find in the fossil record and what we're going to see in this talk today is that homminid fossils generally fit into two categories. Apeike species and humanlike species with a large 07:05 Speaker A unbridgeged gap between them and the fossil record does not clearly document the evolution of humans from ache-ike precursors. Now, I want to briefly touch upon a terminological issue and that is what is a hominin or a hominin? Um these 07:18 Speaker A terms are used diff differently even within the mainstream scientific literature. You can see them used in different ways. But for our purposes today, the term homminid or hominin is going to refer to any member of this lineage that branched off from our 07:33 Speaker A supposed most recent common ancestor with chimpanzees and and belongs on this line of the tree or this lineage that led to modern human beings. That's how we're going to define homminid or homminin in our talk today. Even though 07:46 Speaker A these terms are they are used that way in the scientific literature but they can used be used inconsistently but that's how we're going to use them today. So let's talk about the field of paleoanthropology. This field which studies the the origin of human beings 07:58 Speaker A from the fossil record. Well I'm going to argue that the field of paleoanthropology is fragmented in three different ways. First the fossils themselves are fragmented. Second the record is fragmented in space and time. 08:11 Speaker A And third the field itself is fragmented. Steven J. Ghoul, the famous Harvard paleontologist, said that most homminid fossils, even though they serve as a basis for endless speculation and storytelling, are fragments of jaws and scraps of skulls. Now, Gould said this 08:26 Speaker A in the year 1980, so it's a bit of a dated quote, but I would say this quote still holds true today. The vast majority of homminid fossils that we find are still fragments of jaws and scraps of skulls and maybe a few other 08:39 Speaker A bones as well. But by and large the fossils we find in the field of paleo anthropology are very fragmented. The record is also fragmented. Harvard evolutionary biologist Richard Lewon said that when we consider the remote past before the origin of actual species 08:54 Speaker A homo sapiens, we are faced with a fragmentaryary and disconnected fossil record. Despite the excited and optimistic claims that have been made by some paleontologist, no fossil species can be established as our direct ancestor. And the reason he says this is 09:08 Speaker A because we don't have a complete picture of all the fossils that are out there. 09:12 Speaker A There are a lot of gaps in the fossil record and the record itself is very fragmented. We're still discovering new species of hominids every few years. So the fossil record in paleanthropology is very fragmented. Finally, the field itself is fragmented. I love this quote. 09:28 Speaker A It's from a PBS Nova producer who was doing a documentary on Neanderthalss. And you said each Neanderthal expert I thought the last one I talked to was an idiot if not an actual Neanderthal. So you see this when you read the memoirs 09:40 Speaker A of paleoanthropologists talking about their careers. They they'll tell you great stories about rivaling factions within the field of paleoanthropology. 09:50 Speaker A People refusing to share bones so that other rival competitor labs could could uh essentially critique or evaluate their claims. and they will tell many stories of of lack of objectivity within this field. And I would say that, you 10:04 Speaker A know, this is just human nature. It's the way that science works. But in the field of paleo anthropology, unfortunately, this competitiveness is especially acute. And we have to also we have to always take their claims with a grain of salt knowing that these are 10:17 Speaker A human beings and there's a lot of competition and rivals within the field of paleo anthropology. So the field is also fragmented. Henry Gee, who's a senior editor at one of the world's top journals, nature, said that fossil evidence of human evolutionary history 10:31 Speaker A is fragmentaryary and open to various interpretations. And what I want to ask today is whether the one of the interpretations that we should be open to is the idea that humans did not evolve from apeike precursors. If the 10:43 Speaker A evidence is so fragmentaryary, why is that interpretation disallowed? especially as we're going to see when there is a distinct break in the fossil record and gap right where the origin of humans occurs from their supposed ape-like ancestors. So, let's continue 10:57 Speaker A and let's talk about some of these early hominins and some of the hype that has gone uh on surrounding them. A recurring pattern that we see in this field in this issue is that when a fossil is first discovered, it will be promoted by 11:10 Speaker A the media as the latest human ancestor with lots of hype and fanfare. But then after a few months or maybe a couple years, cooler heads will prevail and scientists will publish papers saying, "You know what? Some of those early 11:22 Speaker A claims or we thought that it was a human ancestor really are not true." And we see the same cycle repeating over and over and over again with different homminid fossils, especially for these early hominids.
