Piltdown Man forgery

1912Contested

In 1912 amateur collector Charles Dawson announced fossils from Piltdown, England, said to be an early human ancestor with a large brain and an apelike jaw. In 1953 scientists proved it a forgery made from a human skull and an orangutan jaw.

The story

On December 18, 1912, Charles Dawson, a lawyer and amateur fossil collector, and Arthur Smith Woodward, keeper of geology at the British Museum, presented to the Geological Society of London pieces of a skull and jaw found in a gravel pit at Piltdown in Sussex. They named the creature Eoanthropus dawsoni, Dawson's dawn man, and argued it was a very early human ancestor with a large, humanlike braincase and an apelike jaw. The find fitted what many British scientists expected: that a big brain had evolved first, and that an important stage of human evolution had happened in England.

For four decades Piltdown distorted the study of human origins and made genuine fossils such as the Taung child, found in South Africa in 1924, harder to accept. In 1953 Kenneth Oakley, Joseph Weiner and Wilfrid Le Gros Clark used fluorine dating and close examination to show the skull was a medieval human, the jaw came from an orangutan, the teeth had been filed down, and the bones were stained to look ancient. A 2016 study by Isabelle De Groote and colleagues found the same methods throughout the finds and concluded that Dawson was most likely the lone forger.

Why it mattered

  • Piltdown's exposure became the standard example of how scientific expectations can make experts accept a fraud.
  • Its removal cleared the way for African fossils such as the Taung child to take their place in the story of human evolution.
  • Creationists and skeptics still cite the case, while scientists point to it as an example of science correcting itself.

Contested history

Consensus: Piltdown Man, announced in 1912 as an early human ancestor, was proven in 1953 to be a forgery assembled from a medieval human skull, an orangutan jaw and filed teeth. A 2016 study concluded Charles Dawson was most likely the sole forger.

Piltdown Man was a deliberate forgeryEstablished
The 1953 analysis by Oakley, Weiner and Le Gros Clark showed filed teeth, artificial staining and mismatched bones, and later tests have confirmed it.

Charles Dawson made the forgeryEstablished
Dawson was linked to other faked finds, and the 2016 study by De Groote and colleagues found a consistent method across all the Piltdown material that points to one person.

Others, such as Teilhard de Chardin or Arthur Conan Doyle, were co-conspiratorsSpeculation
Over the years writers have accused at least a dozen people, sometimes on circumstantial grounds such as their presence at the site. No direct evidence supports any of them.

Piltdown seriously delayed the acceptance of African human ancestorsDebated
Many historians argue it helped British scientists dismiss the Taung child after 1924. Others say other factors, including the limited fossil record, mattered as much.
