Piltdown man, whose fossils were sufficiently convincing to generate a scholarly controversy lasting more than 40 years, was one of the most successful hoaxes in the history of science. In a series of discoveries in —12, Charles Dawson, an English lawyer and amateur geologist, found what appeared to be the fossilized fragments of a cranium, a jawbone, and other specimens in a gravel formation at Barkham Manor on Piltdown Common near Lewes in Sussex.

Woodward claimed that the fossils represented a ly unknown species of extinct hominin Eoanthropus dawsoni that could be the missing evolutionary link between apes and early humans. His claims were eagerly and uncritically endorsed by some prominent English scientists, perhaps because the Piltdown fossils suggested that the British Isles had been an important site of early human evolution. As long as the remains were accorded a high antiquity, Piltdown man seemed a feasible alternative to Homo erectus then known from scanty remains as Pithecanthropus as an ancestor of modern humans.

Inhowever, the Piltdown gravels were found to be much less ancient than supposed, and, frommore finds of Pithecanthropusthe discoveries of the more primitive Australopithecusand further Piltdown hoax dating technique of Neanderthals left Piltdown man completely isolated in the evolutionary sequence. In —54, as an outcome of these discoveries, an intensive scientific reexamination of the Piltdown remains showed them to be the skillfully disguised fragments of a quite modern human cranium about years oldthe jaw and teeth of an orangutanand the tooth probably of a chimpanzeeall fraudulently introduced into the shallow gravels.

Chemical tests revealed that the fragments had been deliberately stained, some with chromium and others with acid iron sulfate solution neither chromium nor sulfate occurs in the localityand that, although the associated remains were of genuine extinct animals, they were not of British provenance.

The teeth too had been subjected to artificial abrasion to simulate the human mode of flat wear. The exposure of the Piltdown fraud clarified the sequence of human evolution by removing the greatest anomaly in the fossil record. The fraud had impeded recognition of the importance of hominin fossils discovered in Africa. The identity of the perpetrator of the Piltdown hoax has remained a mystery. Speculation has most often focused on Dawson himself, who may have been motivated by a desire for a coup that would gain him entrance into the Royal Society. Another possible participant in the scheme was Pierre Teilhard de Chardina French Jesuit priest and paleontologist who accompanied Dawson on his first t excavations at Piltdown with Woodward.

Still other candidates have included the author Sir Arthur Conan Doylewho lived near Piltdown, knew Dawson, and was interested in fossils, and Sir Arthur Keithwho was an Piltdown hoax dating technique and conservator of the Hunterian Museum of the Royal College of Surgeons at the time. The first solid evidence regarding the identity of the perpetrator emerged intwo decades after a trunk marked with the initials M.

Upon analyzing bones found in the trunk, the British paleontologists Brian Gardiner and Andrew Currant found that they had been stained in the exact same way as the Piltdown fossils. The trunk apparently had belonged to Martin A. Hinton, who became keeper of zoology at the British Museum in Hinton presumably used the bones in the steamer trunk for practice before treating the bones used in the actual hoax. A second study, released inappeared to shift the responsibility for the hoax to Dawson. A reexamination of the Piltdown remains, which included spectroscopy and DNA analysis, strongly suggested that the fabricated remains were Piltdown hoax dating technique by combining the bones of a single orangutan and no fewer than two human specimens.

The remains from both sites showed similar patterns of chemical staining, gravel packed into spaces both between and within the bones, bone abrasion from filing, and the use of a cementing material reminiscent of Piltdown hoax dating technique putty to bind various bone fragments together—all of which were likely the work of one person. Although other parties may have been involved at various stages of the ruse, the study implicated Dawson as the common element at Piltdown hoax dating technique of the important points of the story. He discovered the fossil remains at both sites and first brought attention to them by delivering them to Woodward.
