Piltdown Man: The Fraudulent Missing Link?

Posted on by

On December 18, 1912, Charles Dawson and Arthur Smith Woodward announced the discovery of mysterious bone fragments at a meeting of the Geological Society of London. These fragments, which included part of a skull and a jawbone, seemed to prove the existence of a previously unknown human species with chimpanzee-like features. In other words, the Missing Link. What was Piltdown Man?

The Piltdown Man Hoax?

The discovery of the so-called Piltdown Man was greeting with frenzied excitement and some skepticism. But it would take another 41 years before scientists were able to uncover the dark truth about Piltdown Man.

In 1953, Kenneth Page Oakley, Sir Wilfrid Edward Le Gros Clark, and Joseph Weiner used modern chemistry to shed new light on Piltdown Man. In the process, they exposed perhaps the greatest paleontological hoax of all time…Piltdown Man was a fake.

Until that point, researchers believed Piltdown Man had lived 750,000-950,000 years ago. However, fluorine testing showed the bone fragments actually came from three different creatures. The skull was human and just 600 years old. The jaw was 500 years old and came from an orangutan. And the teeth had belonged to a chimpanzee.

The hoax quickly unraveled. The fragments had been treated with chemicals to create the impression of age. Also, someone had filed down the teeth and deliberately removed parts from the fragments to confuse scholars.

Who was behind the Piltdown Man Hoax?

So who perpetrated the hoax? And why? Over the years, historians have pointed the finger at a number of individuals. Even Sir Arthur Conan Doyle of Sherlock Holmes fame has found himself a suspect. However, most people believe the hoax was originated by none other than the discoverer, Charles Dawson himself.

It turns out Dawson had the bad habit of forging other archaeological finds years before Piltdown Man. His personal collection included at least 38 fakes, some of which showed filed-down teeth. He deliberately aged flints with chemicals. And his written work included numerous examples of plagiarism. In short, Dawson had the means to perpetrate the archaeological hoax.

“Piltdown was not a “one-off” hoax, more the culmination of a life’s work.” ~ Miles Russell, Charles Dawson: ‘The Piltdown faker’

As for motive, Dawson once wrote to a friend that he was “waiting for the big ‘find’ which never seems to come along.” This, along with his penchant for creating bizarre fossils and passing them off as real, would seem to imply he was driven by a desire for fame. Finally, Dawson had the best opportunity. Apparently, he was the only person present for the various discoveries of Piltdown fossils over the years. And all such discoveries ceased after his death in 1916.

The New Missing Link?

In 2010, archaeologists discovered the first fossils of Australopithecus sediba, a human-like species that lived in Africa about 1.9 million years ago. Now, extensive analysis shows that these fossils don’t belong to just any old extinct hominids…they might actually represent a direct link in the evolutionary chain of humanity. In other words, a missing link.

The Missing “Missing Link”?

It’s commonly thought that early humans and chimpanzees parted evolutionary ways about five to seven million years ago. The genus Homo proceeded to evolve even further, leading to numerous species and subspecies. Through a process of extinction and introgression, all of these other creatures eventually disappeared, leaving modern man as the sole surviving members of the Homo genus.

But the exact path of human evolution remains a mystery, due to the difficulty in locating ancient transitional fossils (aka missing links). However, its generally accepted that modern humans can trace their lineage back to Homo Erectus, which may have been the first hominid to leave Africa. The ancestors to Homo Erectus are less certain, with scientists taking sides among numerous candidates.

Is Australopithecus Sediba a Missing Link?

In 2010, a team led by Professor Lee Berger announced the discovery of the remains of two early protohumans in South Africa. The bones consisted of an adult female and a boy who most likely died when they fell into an underground cave. The protohumans were dubbed Australopithecus sediba.

After further examination, Professor Berger and his team now believe that this new species, although older than other species typically considered ancestors to Homo Erectus, was actually more advanced in terms of anatomy and likely capabilities. This has led the team to announce that Australopithecus sediba is a more likely candidate for the ancestor for Homo Erectus than the usual suspects. If true, that would make it “on the direct evolutionary line to us.” In other words, it could be a missing link.

“We have examined the critical areas of anatomy that have been used consistently for identifying the uniqueness of human beings. Any one of these features could have evolved separately, but it is highly unlikely that all of them would have evolved together if Australopithecus sediba was not related to our lineage.” ~ Professor Lee Berger, The University of the Witwatersrand

Some of the evidence backing this assertion include:

  • Age: The fossils were dated to 1.977 to 1.980 million years ago, making it old enough to be an ancestor to Homo Erectus.
  • Brain: While smaller than older fossils, the boy’s brain was probably more similar to modern humans in terms of shape. This may indicate “the start of the reorganization of the brain that would be necessary to make us what we are today.”
  • Hand: The adult female’s right hand shares far more in common with modern humans than with apes.

Guerrilla Explorer’s Analysis

So, is Australopithecus sediba a direct ancestor to Homo Erectus and thus, a direct ancestor to us? Is it a missing link? As of this point, scientists aren’t completely convinced. However, many seem to think that it’s a distinct possibility.

“One lineage of Australopithecus almost certainly led into the first member of our own genus called Homo, and from then eventually emerged modern humans. But some of them are side branches, and we’re trying to work out which ones are and which ones aren’t – and that’s why this finding is so important. In many ways, these fossils are the ‘smoking gun’ just before the emergence of our own genus.” ~ Dr. William Harcourt-Smit, American Museum of Natural History

The site where the Australopithecus sediba remains were found is believed to contain more fossils. If so, those fossils may strengthen Professor Berger’s case…and in the process, help to rewrite the history of human evolution as we know it.
