Chapter 7

Pithecanthropus alalus

Darwin thought it probable that humans had evolved in Africa. His reasoning went like this: humans are (“however much the conclusion may revolt our pride”) members of the “catarrhine” or Old World group of primates. (The other group, the “platyrhines,” live in Central and South America.) The ancestors of mankind must therefore have lived somewhere in the Old World other than Australia or the oceanic islands. “In each great region of the world,” Darwin’s logic continued,

...the living mammals are closely related to the extinct species of the same region. It is therefore probable that Africa was formerly inhabited by extinct apes closely related to the gorilla and the chimpanzee; and as these two species are now man’s closest allies, it is somewhat more probable that our early progenitors lived on the African continent than elsewhere.

When the first remains of an extinct kind of human were discovered, however, they turned up in Europe rather than in Africa. Three years before the publication of The Origin of Species in 1859 a skull and some arm, leg and hip fragments had been unearthed near Düsseldorf in the Neander Valley or “Thal.” (“Tal,” in the modern spelling, related to the English “dale,” is the German world for valley.) Ancient human bones resembling those found in the Neanderthal had been unearthed in Europe since 1829. All the remains of extinct humans discovered in Europe in the Nineteenth Century were, in fact, of the Neanderthal type. The limb bones of this kind of human were shorter and more massive than ours are, and their lower jaws sloped back steeply under their mouths, leaving no trace of the chin which juts out under the mouths of our kind of human. Their foreheads also sloped back abruptly from the big ridges of bone over their eyes, and the occipital or hindmost areas of their skulls stuck out further than ours do. The shape of the Neanderthal brain-case, was, therefore, quite different from ours, but its size – its cubic capacity – was the same or a little larger.

Even in the Nineteenth Century, it was already realized that Neanderthals must have been in existence relatively recently. In anticipation of the discovery of the fossilized remains of the much older species whose body-shape and mental capacity must have stood midway between those of apes and humans, a German disciple of Darwin, Ernst Häckel, suggested a scientific name for it: Pithecanthropus alalus – “the ape-man who couldn’t speak.”

Unlike Darwin, Häckel thought that human evolution might have been connected with Asia (through a hypothetical, sunken connection between Africa/Madagascar and the East Indies that he called “Lemuria.”) The East Indies were, after all, also inhabited by “human-like” apes: orangs, gibbons and siamangs. Häckel favored the gibbon as our closest relative. Male chimpanzees and gorillas are, he thought, much bigger than their female counterparts, (an assumption which is only true of the of the latter species) while gibbon males and females are, like those of our species, relatively close to each other in size. Gibbons also walk relatively easily on their hind legs compared to other apes (although they usually hold their immensely long arms above their heads while they’re doing so to keep them out of the way). Häckel also attached significance to the fact that the gibbon is – like he assumed Homo sapiens to be – a monogamous primate.

A talented Dutch anatomist called Eugène Dubois (1858-1940) was one of the many young Europeans of his generation who were fascinated by the new theory of evolution by natural selection. (The Origin of Species had been published a year after his birth.) Initially Dubois couldn’t make up his mind whether Darwin or Häckel was right about where human evolution had started. He eventually settled, however, on Asia. He’d learned from Alfred Russel Wallace’s biogeographical writings that Java and Sumatra had been joined to Asian mainland during the glacial periods. He knew, too, that those islands had never been covered by ice the way large parts of Europe had been. He may have been influenced, also, by the convenient fact that the East Indies, of which Java and Sumatra were parts, were Dutch colonial possessions. Against the advice of family and friends, he resigned a promising academic appointment, and joined the Dutch army as a surgeon to enable him to travel, as he did in 1887, to the Indies to look for Häckel’s Pithecanthropus.

Dubois’ first excavations, conducted in Sumatra, were undertaken whenever he could take time off from his medical duties. He was so successful, however, at unearthing the remains of extinct animals that he was eventually able to persuade the Dutch government to turn his paleontological investigations into a formal part of his duties, and grant him funds to expand them.

Five years after his arrival in the Indies, excavating a promontory jutting into the Solo river near the Javan village of Trinil, Dubois’ workers unearthed the skull-cap of a large primate. This skull-cap, which included the “supra-orbital margins” (i.e. the top edges of the eye-holes), was complete enough to allow a reasonable estimate of its original capacity: about 850 cc. This was a significant number because it lies about halfway between the average cranial capacity of the bigger anthropoid apes (around 450 c.c.) and that of humans (1375 c.c.). That must have seemed like a strong indication that the skull-cap could be that of the midway-between-apes-and-humans species he’d come to the Indies to find.

Dubois was initially inclined, however, to think that the skull had been that of an ape. The fact that its capacity was larger that of any of the contemporary ape species might, he feared, merely have reflected the fact that it was merely that of an exceptionally large kind of ape. A year later, however, and some fifteen meters from where the skull-cap had been found, Dubois’ workers found a thigh-bone – a femur – that was indistinguishable from that of a modern human. The Trinil site also yielded a molar tooth which was completely human in appearance. Because the femur and the molar were found in the same layer of gravel which had contained the skull-fragment, Dubois concluded (correctly, as subsequent finds would show) that all three were remains of the same species. The human characteristics of the latter two finds persuaded him that the species in question wasn’t the “pure ape” that he’d originally feared it might be, but that it was, in fact, the ape-man he’d come to the East Indies to find.

Because its very human-like femur suggested strongly that his “ape-man” had walked upright, Dubois named his find Pithecanthropus erectus rather than P. alalus. It’s ironic that Dubois initially feared that skull he’d discovered was too ape-like to be the Pithecanthropus he was looking for, because erectus turned out, in the end, to be too human to be an “ape-man.” The size of its brain was, as we’ve seen, only about halfway between that of our brains and those of the great apes, but that was erectus’ only ape-like feature. Subsequent discoveries would show beyond doubt what the Trinil femur and molar tooth already hinted at: that the rest of their owner’s anatomy was overwhelmingly human-like. The species discovered by Dubios is now referred to, therefore, as Homo erectus rather than Pithecanthropus erectus. The rules of scientific nomenclature tell us that the “erectus” part of its name is here to stay, but it, too, has become inappropriate: later finds have made it clear that erectus could not (as its name might suggest) have been the first human-like being to walk on two legs.

But Pithecanthropus erectus was still an immensely important discovery. It represented, after all, an extinct human species that was older than the Neanderthals. Returning to Europe in 1895, Dubois exhibited its remains at a series of lectures and discussions.

Enter Rudolph Virchow, a famous German pathologist who’d become widely accepted as the leader of, and spokesperson for, the German scientific community. (Unappreciative members of that community referred to him as “the Nabob” or “the Pasha.”) Virchow had previously dismissed the Neanderthal finds as the bones of modern humans which had been distorted by disease. Now he rejected the idea that Dubois had found a human-like being as the “the purest fantasy imaginable.” The remains Dubois had dug up in Java were, Virchow explained, those of a giant gibbon.

Seen in a wider context, Dubois’ battle with Virchow was just another action in the civil war that was being waged at the time between scientists who accepted Darwin’s views, and those, like Virchow, who didn’t. Dubois would not, however, have been inclined to adopt a philosophical perspective on Virchow’s dismissal of his extraordinary discovery. A proud man, sensitive to the point of paranoia, Dubois was short on both tolerance and what we’d now call people-skills.

Even those who agreed with his proposition that Pithecanthropus was not an ape could pose a threat to Dubois’ peace of mind. A Strassbourg anatomist named Gustav Schwalbe travelled to Leiden to examine the Trinil find and became convinced, as a result, that Pithecanthropus was the beginning of an evolutionary sequence that had run through the Neanderthals to culminate in Homo sapiens. The publication of this theory advanced both Dubois’ cause and the new science of paleoanthropology, but it also provided a hefty boost for Schwalbe’s own professional reputation. In his Eugène Dubois and the Ape Man from Java, Bert Theunissen reasons that Dubois resolved, as a result of that boost, not to allow anyone else to examine the fossils until he himself had published a full description and analysis of them. Schwalbe had come close to stealing his thunder, and Dubois did not, Theunissen surmises, want to take the risk of that happening again. This, Theunissen thinks, is the reason why Dubois would not permit anyone else to examine his Pithecanthropus fossils after 1900. Dubois’ refusal was to remain in effect, however, for nearly three decades.

Remains similar to those of Pithecanthropus erectus started showing up in the 1920s and 30s. The first of them came from China. On the basis of a series of finds from Zhoukoudian near Beijing from 1927 to 1933, the Canadian anatomist Davidson Black described a new species called Sinanthropus pekinensis. Sinanthropus was, in Black’s view, very similar to Dubois’ Pithecanthropus. Franz Weidenreich, who succeeded Black after the latter’s premature death in 1933, agreed with this view. Both Sinanthropus and Pithecanthropus belonged, Weidenreich thought, in the Hominidae or human family, rather than the half-ape, half-human “Pithecanthropoidae” family which Dubois had created for the latter.

Dubois reacted to this idea with indignation, and tried to refute it in a 1936 article entitled “On the Gibbon-like Appearance of Pithecanthropus erectus.” Nearly forty years before, Dubois had to emphasize the human-like characteristics of Pithecanthropus to rebut Virchow’s claim that it was “merely” a large form of gibbon. Now he needed to emphasize its supposedly gibbon-like qualities to counter Weidenreich’s assertion that it was “merely” a human.

Then new finds were made in Java. In 1936 at Modjokerto, and in 1937 at Sangiran, Ralph von Königswald discovered two more skulls which also seemed similar to Dubois’ Pithecanthropus. Originally thought to be about a million years old, these have now been dated by the Argon 40/Argon 39 (“Ar/Ar”) method at 1.81 and 1.66 million years old respectively. Von Königswald named a species called Pithecanthropus modjokertensis on the basis of the first of these finds, provoking a vehement objection from Dubois. The Trinil primate – his primate – was, Dubois insisted, the only member of the Pithecanthropoidae family to have been discovered up to that time. Von Königswald relented and renamed the species Homo modjokertensis (but continued, we’re told, to refer to it as Pithecanthropus in private). The ear-hole and part of the jaw of the Sangiran specimen – areas which had not been preserved in Dubois’ find – demonstrated beyond question that its owner had been a very human-like being. Von Königswald and Weidenreich now made a detailed comparison between the Javan and Chinese material, and came to the conclusion that all the Asian finds, including Dubois’ so-called Pithecanthropus, were “related to each other in the same way as two different races of present mankind.” By the second half of the Twentieth Century, all the Asian finds, including Dubois’, were being referred to, as we’ve seen, as Homo erectus.

Dubois himself agreed that Davidson’s Sinanthropus was a member of the Hominidae – he thought it was a kind of Neanderthal. He was also comfortable with (and indeed, as we’ve seen, insistent on) the idea that von Königswald’s Javan finds were members of the human family. To the day of his death in 1940, however, at the age of 82, he clung to the belief that his find was not a member of that family, but of the ape-man family “Pithecanthropoidae.”

Among the first scientists to support Dubois’ 1895 claim that his Javan primate wasn’t “just an ape,” were a Scot called Arthur Keith, and an Australian called Grafton Elliot Smith. Both these men were young near the turn of the twentieth century, and both, as one might suspect from their receptivity to Dubois’ claim, were evolutionists. Keith didn’t only accept the fact that Pithecanthropus had human-like attributes – he accepted, too, the idea that it had been completely adapted to upright walking.

The fact that it had a comparatively small brain persuaded Keith, however, that Pithecanthropus must have occupied a side-branch of the human family. Like many of the anatomist-anthropologists of their time, Keith and Elliot Smith thought that the ancestor of Homo sapiens must have developed a big, intelligent brain before it had become capable of walking upright. “It was not,” as Elliot Smith put it, “the adoption of the erect attitude that made Man from an Ape, but the gradual perfecting of the brain, and the slow upbuilding of the mental structure, of which erectness of carriage is one of the incidental characteristics.”

Keith was in agreement with this view:

He [Elliot Smith]... rightly foresaw that before the anthropoid [i.e. ape-like] characters would disappear from the body of primal man, the brain, the master organ of the human body, must first have come into its human estate. Under its dominion, the parts of the body such as the mouth and the hands, the particular servants of the brain, became adapted to higher uses.

In addition to sharing the then-current “big brains came first” view of human evolution, Arthur Keith also believed in what he called “man’s antiquity” – the idea that Homo sapiens had evolved its “true human” or “modern” form much further back in time than was generally believed. He believed, therefore, that a big-brained being, very similar to Homo sapiens, had already been walking upright before either the Neanderthals or Dubois’ small-brained Pithecanthropus came into existence.

He supported this notion by suggesting that several of the modern-looking skulls that had been discovered in England itself – most notably the Galley Hill skull which had been found in 1888 – were extremely ancient. But Galley Hill and the other supposedly “ancient” British remains did not, in fact, possess any features which would support the idea of “the vast antiquity of true humans.” Apart from a somewhat-greater-than-average thickness in the Galley Hill skull, the “primitive” features that Keith saw in it simply weren’t visible to his fellow-anatomists. Galley Hill and all the other remains for which Keith claimed “great antiquity” are now universally viewed as recent material.

In 1907 a human fossil which really was extremely old turned up in Europe. After unearthing mammalian remains which included many extinct mammals in the district of Mauer over a period of some twenty years, Otto Schötensack, a professor of geology at nearby Heidelberg University, found a big, robust lower jaw which lacked the kind of protruding chin which Homo sapiens possesses. The big jaw was beautifully preserved, and structures like the “symphases” or joins between its constituent parts, confirmed the already-clear message conveyed by its teeth: its owner had been human. The level at which the jaw was found, and the kinds of animals that were found with it, made it clear, though, that the Mauer human had lived long before the Neanderthal form emerged. (The Mauer jaw is presently thought to be about 600,000 years old, while the classic Neanderthal form only appeared about 130,000 years ago.)

Schötensack named a new human species on the basis of the jaw: Homo heidelbergensis. No skull parts or other human bones were found in association with the jaw, so its finders could not tell whether heidelbergensis had either a “modern” skull-capacity or a “modern” ability to walk upright.

Then, in 1912, an even more startling find was made – this time in England. Human skull-fragments were found together with an ape-like jaw-fragment in a gravel pit on a farm near Piltdown Common in the county of Sussex. The ape-like jaw-fragment bore two seemingly human-like teeth. Most people concluded from this, and from the fact that the skull fragments and jaw had reportedly been found so near to each other, that the skull and the jaw must have belonged to the same species – and, in fact, to the same individual. The skull fragments were clearly those of a human species, but that human species must, judging by its ape-like jaw, be an older one than heidelbergensis with its obviously human-like jaw. This reasoning emboldened Arthur Smith Woodward, keeper of geology at the British Museum of Natural History, to create a new genus with the grandiloquent name Eoanthropus – “Dawn Man” – for the Piltdown find.

This impression of great age was reinforced by the remains of extinct animals (mainly tooth fragments) that were associated with the Piltdown find: two fragments of molar teeth represented what was apparently a Pliocene mastodon, and the third, a Pliocene stegodon. Tooth fragments representing hippopotamus and beaver species which could also have lived in the Pliocene were found in the same deposit. The Piltdown pit where these finds had been made also yielded stone and bone implements from a seemingly early stage of human technology.

Woodward had been present when that jaw had been dug out of the ground by his friend Charles Dawson, a solicitor who was an amateur archeologist and paleontologist. Early in 1912, Dawson had written to him that workmen had – some years previously – unearthed, and broken, a human skull in a gravel-pit on a farm near Piltdown Common in the county of Sussex. A short while after he’d sent this report to Woodward, Dawson brought a fragment or fragments of the skull to London. The bone was extraordinarily thick. “How’s that for Heidelberg!” he is reported to have called out as he handed the material to Woodward. Woodward took the bait, and, over most of the weekends in the summer of 1912, he travelled to Sussex to search, together with Dawson, through material dug from that pit. On a few occasions, the pair was assisted by a 31-year-old French priest by the name of Teilhard de Chardin who both of them had known previously. Dawson found most of the rest of the human and animal remains which came out of the Piltdown gravel pit during that summer, including the ape-like jaw-fragment, but Teilhard and Woodward also made a few finds.

Placing Eoanthropus as far back as the Pliocene would not only confirm that it had lived before Homo heidelbergensis – it would suggest, in fact, that Eoanthropus’ age must rival or exceed that of Dubois’ Pithecanthropus. Notwithstanding this, however, the Piltdown skull had clearly housed a brain which was about the same size as that of a modern human. If a big brain had been the first distinctively human characterisic to develop, then Eoanthropus must surely have a better claim to human ancestry than the small-brained Pithecanthropus.

A number of anthropologists doubted, however, that so “modern” a human skull could have been combined in the same species with such an ape-like jaw. These doubters – the so-called “dualists” – felt that the Piltdown skull and jaw must represent two different species: a human and an ape. An American paleontologist even created a new species for the presumed ape: Pan vetus – “ancient chimpanzee.” The feeling among these dualists was that the skull was probably an “intrusive” object, i.e. one that might have been buried in the ancient deposit containing the ape-like jaw at some relatively recent time. But if that were so, then why were the walls of its skull as thick as, or thicker than, those of a Neanderthal skull?

As the controversy over Piltdown burned bright, the careers of those associated with the find were brilliantly illuminated. Woodward had enjoyed his share of professional honors before Piltdown – he’d been made a Fellow of the Royal Society on the basis of his work in marine paleontology as early as 1904 – but his close association with Dawson’s find, turned him into a scientific celebrity. Taking part in that find was, as he described it to a newspaper reporter in 1924, “the most important thing that ever happened in my life.”

Arthur Keith, who had played a prominent part in the evaluation and reconstruction of the skull, received an even bigger boost from its “discovery.” Keith’s reconstruction of Eoanthropus became the centerpiece of the anthropological exhibit at the museum of which he was the Conservator. People flocked to Keith’s museum lectures in record numbers. Piltdown wasn’t only the centerpiece of those lectures and exhibits – it became the centerpiece of Keith’s career.

Before Piltdown, that career had been in the doldrums. In 1900, Keith had written a book entitled Man and Ape – a Statement of the Evidence of Their Common Origin as it Stands Today. After the manuscript was completed, his publisher, John Murray, had second thoughts about its saleability. Murray praised the book’s scientific merit, but refused, despite the fact that he’d signed a contract with the Keith, to go through with its publication.

“Murray’s rejection of the book,” Keith would later write, “was my bitterest disappointment in my struggle for place and reputation among my fellow anatomists.” During the next eight years, Keith worked as an anatomy demonstrator, publishing some work on the human heart. Finally, in 1908, he was appointed as the Conservator of the Hunterian. This was a big step up for Keith, but the new job was still, in anthropologist-historian Pat Shipman’s words, “a relatively obscure post that he found unsatisfactory.”

Keith would have to swallow more disappointments before his career would finally take off. In 1911, when he was already forty-five years old, the Royal Society gave him what he described as a “slap in the face” by rejecting his application for membership. (Elliot Smith had, by contrast, been given his FRS in 1907, at the age of 36.) Keith re-applied in 1912, a few months before the Piltdown discovery was announced, and was again rejected.

It was only in 1913 – after his association with Piltdown had thrust him into the public eye – that Keith was finally admitted to the Royal Society. The Man and Ape book which John Murray had rejected, now metamorphosed into a new work entitled The Antiquity of Man. Published in 1915, Antiquity was dominated by discussion of Piltdown. An image of a skull entitled “Piltdown fragments” was embossed in gold on its front cover. In 1921, Keith was given a knighthood. “He has gone up,” one of his contemporaries wrote in 1924, “like a rocket...”

 

* * *

Piltdown was, of course, exposed as a fraud in 1953. Charles Dawson, a solicitor who practiced at Uckfield near the Piltdown site in Sussex at the time of the “discovery” was clearly the perpetrator of that fraud. John Walsh’s 1996 book Unravelling Piltdown gives a carefully-substantiated and devastating account of the string of faked archeological and paleontological “discoveries” that Dawson concocted before he engineered the Piltdown “discoveries.” Dawson added old-fashioned business fraud and plagiarism to those scientific frauds. Walsh’s book gives Dawson’s reponsibility for the Piltdown fraud what Richard Bernstein called, in a 1997 New York Times review, “the solidity of a Euclidean proof.”

The skull of Dawson’s supposed “dawn man” was in reality that of a recently-living human. Its greatly-thickened condition was the result of a disease called rachitis or rickets. The jaw fragment was that of a young female orang-utan which had been alive even more recently than the owner of the skull. The characteristic high cusps of the two teeth it contained had been filed down to give them a human appearance. At the start of his investigation, Joseph Weiner, a member of the three-person team that proved that Piltdown was a fake, suspected only that Piltdown’s ape-like jaw was a forgery or “plant.” He was astonished, therefore, to discover that none of the 37 pieces of bone and stone “found” at Piltdown were genuine. They had all been brought from elsewhere, and all chemically stained reddish-brown to match the color of the gravel in the pit in which they were “found.” Ten other faked objects were, in addition, “found” at two other sites near Piltdown.

The second of these two subsequent “discoveries” consisted of human skull-fragments which Dawson reported finding in 1913 at Barcome Mills (some four miles away from Barkham Manor, the original “Piltdown” site). Nobody challenged the genuineness of this “find,” but Arthur Smith Woodward didn’t announce it as another specimen of Eoanthropus. “It is not a thick skull,” Dawson had written to Smith Woodward, “but it may be a descendant of Eoanthropus.

The third human “find” was reported by Dawson at the beginning of 1915. This one consisted of two cranial fragments, the altered molar from the lower jaw of an ape (which probably came from the same orang jaw that had been “found” at the first site) and a fragment of a rhinoceros molar. This time Dawson was able to claim confidently that he’d found another Eoanthropus. “...the general thickness,” he wrote, announcing the “discovery” of one of the skull fragments to Smith Woodward, “seems to me to correspond with the right parietal of Eoanthropus...”

Dawson told Woodward that this latest group of bones was found “on the Sheffield Park Estate.” He would not, however, tell Woodward the exact place where he found them. Two full years were to go by before Woodward would announce the Sheffield Park “find.” Had a kind of standoff developed between the two men, with Woodward saying he wouldn’t announce the find until Dawson told him exactly where he’d found it, and Dawson threatening to make it public via some other member of the scientific community if Woodward didn’t stop delaying? We know that Dawson did tell Ray Lankester (an Oxford professor of anatomy, later attached to the Natural History Museum) about the new “find,” because the latter inserted a footnote in his 1915 Diversions of a Naturalist, which stated that Dawson had discovered “a second skull of the same character as the first.”

Woodward’s wife later vividly recalled this uneasy and troubled interlude, explaining that Dawson “would not give details of the exact spot” and that her husband on his own “spent much time searching for it” fruitlessly.

Toward the end of 1915 Dawson became ill with anemia. In August of 1916, he died at the age of 52. Dawson’s widow passed the Sheffield Park bones and teeth to Woodward. Woodward questioned her, and other associates of Dawson, in vain to get a better idea of where Dawson had found them, delaying the announcement of “Piltdown Two” for another six months after Dawson’s death. He must have agonizing about whether he should make that announcement at all. If he decided not to do so, he would have to explain why he wasn’t doing so – Dawson had, after all, already leaked the news of the “discovery” before his death. If he made the announcement, on the other hand, and qualified it with an honest admission that Dawson had refused to tell him exactly where he’d found the material, he would not only have raised a big question mark in relation to “Piltdown Two,” but would also have aggravated the doubts that many people were already feeling about Piltdown One.

In the end, the benefits of covering up the truth proved to be too tempting for Woodward. At a meeting of the Geological Society on February 28, 1917, he reported that a second set of Eoanthropus remains had been found on a “large field about 2 miles from the Piltdown pit.” He implied that he knew where that field was, by adding that he and Dawson had already examined it “several times without success during the spring and autumn of 1914.” “Not then, not[r?] ever afterward,” Walsh tells us, “did Woodward further identify or even refer to the ‘field’ he specified so prominently in his official report.”

The announcement that a second thick-boned skull had been found at a separate location, together with a lower molar tooth very similar to the teeth contained in the ape-like jaw of “Piltdown One,” silenced the critics who were maintaining that the skull and jaw of Piltdown One could not represent a single species. “Gradually,” Walsh tells us,

over the next several months and years, accelerating with the war’s end in November 1918, many experts who had vehemently opposed the combination of jaw and cranium now simply gave way, confessing themselves wrong. The conversion, while by no means complete, was dramatic and sweeping, affecting some of the leading names in the field worldwide...

Woodward had known Dawson since 1891, when they were both 27 years old. In that year Woodward, an assistant at the Natural History Museum, collaborated with Dawson on the description of the tooth of a mammal-like reptile which had come into the latter’s possession. Woodward admitted that the only thing which distinguished this tooth from those of similar mammals, was its wear-pattern. Deciding it must represent a new species in the genus Plagiaulax, Woodward called it P. dawsoni in honor of its discoverer.” Dawson had, however, fraudulently modified this tooth to give it the wear-pattern that had brought Woodward to that conclusion. The “Plagiaulax” tooth was among the first of many of many faked objects Dawson tried, with varying degrees of success, to foist on the scientific community.

The Plagiaulax affair also showed, as Walsh points out, how “pliant and accomodating” Woodward could be in such matters. Woodward’s credulousness, and the extent to which Dawson would test it, were, in fact, both quite astonishing. In a letter written on October 7, 1907, Dawson tells his friend that, some 18 months previously, he and other passengers on the cross-channel ferry Manche, had a four-minute sighting of a sea-serpent. A detailed discription of the serpent, whose length was “sixty to seventy feet at the smallest computation,” follows. Dawson adds that he’d exchanged cards with fellow-passengers who could confirm the sighting.

It’s not hard to agree with Walsh that this latter incident “...betrays the forger’s utter confidence in being able to manipulate, almost to play with, the susceptibilities of his old friend, the country’s leading expert in marine paleontology.”

The Piltdown fraud was emphatically not, as the late Stephen Gould argued it was, a “schoolboy prank that got out of hand.” Much more time, effort and care were devoted to it than are spent on what we usually think of as pranks. As we’ve seen, the fraud didn’t just consist of planting a single ape jaw fragment with pieces of a human skull – it involved the appropriation and modification of a much larger number of specimens than that. As we’ve also seen, some forty-seven pieces of bone and stone were assembled, broken, shaped and/or stained in the course of perpetrating it. These pieces were then “found,” or planted for others to find, at Piltdown or reported by Dawson as having been found elsewhere, over a period of three years. The intense and sustained nature of this effort makes no sense unless we accept that it was directed at the attainment of some non-frivolous, non-trivial goal.

That goal could only have been the achievement of scientific recognition (together, of course, with the social and financial benefits that such recognition would entail). None of Dawson’s previous scientific frauds and fakeries were “pranks” – all of them were squarely and rationally aimed at obtaining scientific credit. Dawson did, in fact, reap a considerable degree of acclamation for his “discovery” of Eoanthropus dawsoni, but not as much as he’d hoped for. He was turned down for the coveted FRS – Fellowship of the Royal Society – despite the fact that his name was put up for consideration each year between 1913 and his death in 1916.

Nearly everyone who was directly involved with Piltdown (and several others on the periphery) have been suspected of conspiring with Dawson to commit the fraud. During the 1990s Arthur Keith was in fashion as a suspect, with two scholars, Phillip Tobias and Frank Spencer, building detailed cases against him.

Keith was as capable of covering up truths that may have cast doubts on Piltdown’s authenticity as Woodward was. Although the Piltdown skull did not, for instance, display the gross deformation which is sometimes brought about by rickets, it did bear less prominent indications of having been affected by that disease. The first person to spot those indications seems to have been S. G. Shattock, who was in charge of the largest section of the Hunterian museum – that concerned with pathological lesions of the human body. Shattock examined the Piltdown skull fragments soon after they were “found,” and concluded, in a 1914 Hunterian publication that

... certain details of of the Piltdown calvaria [top of the skull]... suggest the possibility of a pathological process having underlain the thickened condition.

In an attempt to establish the specific nature of the “pathological process,” that may have thickened the skull, Shattock excluded the possibility of acromegaly and six other potentially bone-deforming conditions. He stated specifically, though, that he could not exclude “a past rachitis that has been followed by a reconstruction of the bone.”

A year later, however, commenting on what he called the “surprising” thickness of the Piltdown skull, Arthur Keith made the following assertion in his Antiquity of Man:

The bone is naturally formed; there can be no question of disease. My colleague Mr. Shattock definitely settled this point.

As I see it, that lie is on a par with Woodward’s lie about the “large field” in which Dawson was supposed to have found Piltdown Two. Neither constitutes proof of active conspiracy with Dawson, but both were calculated to hide such manifestly suspicious aspects of the Piltdown “find,” that one feels that the two men who told them were guilty of something almost as serious. Woodward’s announcement, in particular, about where Dawson was supposed to have found Piltdown Two must make him an accessory after the fact to the latter’s fraud.

Paleoanthropology can be a bruising business. We’ve seen how it led to disillusionment and isolation for Eugène Dubois. It can, however, also produce very big rewards. In a 1954 letter to Ashley Montague, the 88-year-old Arthur Keith talked about those rewards, prefacing his remarks with a descripton of the “finder” of the Piltdown skull. “So compelling,” he wrote, “was the honesty of Dawson’s manner of speech that not a single soul of us, doubted his word,” “Yet,” Keith continued,

I have now no doubt that he was the author of all the fraud. And you will ask – what could have been his motive? If you knew the wonderful fame won by Shoetensack in 1907 by the discovery of the Heidelberg jaw – you would realise the fame waiting for the discoverer of a skull of that early date.

As one of the chief beneficiaries of Dawson’s “discovery,” Keith had, as we’ve seen, plenty of personal experience of the “wonderful fame” important finds in the field of human paleontology could generate.

In the 1920s, many if not most anthropologists regarded “Piltdown man” as a direct ancestor of our species, and the oldest such ancestor, moreover, to have been found to date. The faked human species fit in perfectly with widely-accepted beliefs of its time. It supported both the “big brains came first” view, and a “Europeans came first” belief. It appeared at a time when European civilization in general, and the British Empire in particular, could still look like the crowning achievements of human evolution. It made sense to many that the evolution of our species must have begun in the place where those achievements were realized. How else could one explain why Western Europe – and England in particular – seemed to have enjoyed a head start in the race for political, technological and cultural ascendancy?

All these comfortable assumptions were to be challenged in 1924, when a young Australian called Raymond Dart discovered a real ape-man – the very Pithecanthropus alalus whose existence Häckel had postulated – in the most “uncivilized” of all the continents: Africa.
