Henry Fairfield Osborn and the Tragic Legacy of Piltdown Man

Scientists are supposed to be dispassionate professionals. We see them as thoughtful skeptics, seekers of truth, speaking about nature as science reveals it, even when the revelations differ from what we imagined, or from what we may have wished to be true. The truth is that scientists do have passions. They are people with dreams, ambitions, and preconceptions. They want certain things to be true, and certain things to be false, just like anybody else. Science has evolved to compensate. At conferences , scientists ask questions of one another and debate Figure 1 , plus there is a process of formal peer-review.

Piltdown Man Hoax, 100 Years Ago

To bolster his arguments, Osborn, who was president of the American Museum of Natural History from to , turned the considerable resources of his institution toward the development of a wide range of compelling visual materials — reconstructions, painting, charts, graphs and photos — that illustrated his story of evolution. He then distributed these materials freely to textbook publishers and the popular press.

He attended Challoner’s Grammar School and University College School before enrolling at University College London where he graduated with a first class honours BSc in geology with anthropology as a subsidiary subject in , as well as gaining the Rosa Morison memorial medal. Oakley began his PhD at the University of London in , but did not complete his research until due to his appointment to the geological survey in and his post as an assistant keeper in geology palaeontology at the Natural History Museum the following year.

The Natural History Museum would be where Oakley spent the rest of his working life, except for a war service secondment to the geological survey. Oakley became a Fellow of the Society in , gaining the Wollaston Fund award in and the Prestwich Medal in In , Oakley became head of the new sub-department of anthropology within the department of anthropology and held the title of deputy keeper anthropology from to However he developed multiple sclerosis, which forced his premature retirement.

Although eventually confined to a wheelchair, Oakley continued to study and publish work on anthropology until his death on 2 November Oakley’s major area of interest was in early hominid fossils, particularly the use of technologies to date finds. In the s, he began work with various colleagues on methods of dating bone by analysis of fluorine content.

One of the early results of this technique, was finding that a supposedly Middle Pleistocene human skeleton from Galley Hill, Swanscombe, was actually much younger than the gravels in which it was found.

Piltdown Man hoax a sorry saga of science

Great excitement greeted his find, as at the time fewer than five human fossils had been discovered and most of those were incomplete, their dates uncertain and — almost worst of all at a time of intense imperial rivalry — they were foreign. France and Belgium had long boasted Neanderthal skeletons. Germany had Heidelburg Man. Now here, at last, was the first great British palaeoanthropological find.

Piltdown Man consists of five skull fragments, a lower jaw with two teeth and an isolated canine. The first fossil fragment was allegedly unearthed by a man digging in gravel beds in Piltdown in East Sussex, England. The man gave the skull fragment to Charles Dawson, an amateur archaeologist and fossil collector. In , Dawson did his own digging in the gravel and found additional skull fragments, as well as stone tools and the bones of extinct animals such as hippos and mastodons, which suggested the human-like skull bones were of a great antiquity.

In , Dawson wrote to Smith Woodward about his finds. The two of them—along with Pierre Teilhard de Chardin, a Jesuit priest and paleontologist—returned to the Piltdown gravels to continue excavating. They found additional skull fragments and the lower jaw.

The Piltdown Man was a paleoanthropological fraud in which bone fragments were presented as the fossilised remains of a previously unknown early human. Although there were doubts about its authenticity virtually from the beginning, the remains were still broadly accepted for many years, and the falsity of the hoax was only definitively demonstrated in An extensive scientific review in established that amateur archaeologist Charles Dawson was its likely perpetrator.

In , Charles Dawson claimed that he had discovered the “missing link” between ape and man. These finds included a jawbone , more skull fragments, a set of teeth, and primitive tools. Smith Woodward reconstructed the skull fragments and hypothesised that they belonged to a human ancestor from , years ago.

This fortuitous find — nine pieces of a large-brained human skull and an ape-like lower jaw with two teeth — was readily accepted by the British establishment due to their belief that a large brain was one of the first human features to evolve. In , advanced analytical and dating techniques proved Piltdown Man to be a fake. The mandible was stained with potassium bichromate and the teeth had been filed down. Fluorine testing proved that the pieces of the skull were of different ages.

This was confirmed in by carbon dating, which provided a date of about years for the skull! Although the hoaxer has never been identified, the strongest case has been made against Charles Dawson as the perpetrator. The only question really is whether he did it on his own or was assisted by a scientist. Could a similar hoax happen today?

Monkey Puzzle

Piltdown Man. A Europe wide search for the missing link between ape and man continued throughout the second half of the 19th century. Britain was largely ignored until in Charles Dawson found pieces of a skull in a quarry in Piltdown; it was thought to be that of an ancient Pleistocene hominid. In the following years between and another skull was found and an elephant molar and canine tooth were also discovered.

Piltdown man had a large cranial space, a simian jaw but humanoid teeth.

Piltdown Man was a notorious hoax perpetrated early in 20th century Great Britain , in which a medieval human skull was combined with the lower jaw of an orangutan and subsequently “found” in a gravel pit in the near the village of Piltdown, England. Hailed as the ” missing link ” between man and ape-like species by promoters of evolution for decades, Piltdown man was exposed as a fraud only through later scientific testing and simple observation.

The refusal of the discoverer to allow independent scrutiny of his claims enabled this fraud to persist for over forty years. Critics of evolution believe that the Piltdown man was not an isolated incident of bad judgment by evolutionists and that the examples of the Nebraska Man, Java Man, Ocre Man, Neanderthals , and Flores Man can be cited.

In February Arthur Smith Woodward of the British Museum received a letter from a Sussex lawyer named Charles Dawson about a discovery he had made while excavating a gravel pit. What Dawson had described were fragments of a skull cap belonging to an ancient human; the skull was found in in the Piltdown region; other fragments were recovered in , along with animal bones. Excitement over the findings resulted in a more comprehensive excavation in June, , allowing the recovery of more skull fragments, part of the mandible, additional animal bones and stone tools.

Shortly afterward, Piltdown Man was declared the most important fossil find in Europe. The fossil human skull and mandible to be described by Mr. Charles Dawson and Dr. Arthur Smith Woodward at the Geological Society as we go to press is the most important discovery of its kind hitherto made in England. The specimen was found in circumstances which seem to leave no doubt of its geological age, and the characters it shows are themselves sufficient to denote its extreme antiquity.

Its “extreme antiquity” was thought to have been between ,, years ago, based on the animal teeth found with the remains.

Oakley received a B. He was long associated with the British Museum of Natural History —69 , from which he retired in He won renown in when he played a decisive role in the exposure of the Piltdown hoax. The famous Piltdown man , remains of a skull found in a ditch in Sussex, England , had been unchallenged as the missing link between man and ape since its discovery in By applying his fluorine-dating method, Oakley confirmed that the remains were fraudulent.

New dating technology based on fluorine testing emerged in , but the Piltdown remains had been locked away after Dawson’s death in.

Fluorine dating is a method that measures the amount of fluoride absorbed by bones in order to determine their relative age. Unlike radiometric dating methods, it cannot provide a chronometric or calendrical date. Fluorine dating provides only a relative date for bone, revealing whether specimens are older or younger than one another or if they are of the same age Berger and Protsch, ; Lyman et al.

Fluorine dating relies on the discovery that bone mineral, calcium hydroxyapatite, will absorb fluoride ions if, during burial, it is exposed to groundwater that contains fluoride. Groundwater and soil in most parts of the world contain small amounts of fluoride, and these ions can replace the hydroxyl ions in bone mineral to form fluorapatite. Bones absorb fluoride over time, and as a result, those that Skip to main content Skip to table of contents.

Relative Techniques. In the past, relative dating methods often were the only ones available to paleoanthropologists. As a result, it was difficult to chronologically compare fossils from different parts of the world. However, relative methods are still very useful for relating finds from the same or nearby sites with similar geological histories.

The oldest and the simplest relative dating method is stratigraphy , or stratigraphic dating. It is based on the principle of superposition , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. This principle is logical and straightforward. However, geological strata are not always found to be in a neat chronological order. Wind and water erode strata and some areas are uplifted or even tilted.
