- Rating: 4 out of 5 stars4/5Now I know more about human, hominid, australopithecine and related brains that I ever thought I'd know. As it turns out, there is a discipline called paleoneurology which main subject is the endocasts of brains of fossils which may be in our ancestor tree. The human brain is a soft tissue, it disintegrates first so chances of fossilized brains of species from long ago is almost non-existent (they will be destroyed before they fossilize). And here come the endocasts - as it turns out, the brain leaves a pretty good print on the internal side of one's head - so when it is sufficiently preserved, the scientists can do a lot with those prints. And this is what Dean Falk does in her day to day job. The book takes two fossils - the Taung child (found in 1925) and LB1 (the Hobbit found in 2003 in Flores) - and compares their discovery and acceptance from the community. The reason why these two are used is very simple - both allow for full endocasts and both had been studied this way (plus just now, any book about fossils that does not mention LB1 probably has no chance to be published... ). It all starts with a chance discovery in South Africa in 1925 and with the right man at the right place. Fast forward to more recent times and the author finds a huge mistake in the interpretation of part of the brain of that chance discovery (which noone else had found before) and follow a long time of papers in both directions. Falk does not bore us with all of those but the tone in that part of the book is a definitive "I am right, everyone else is wrong" and "Alone against the world". Don't get me wrong - I suspect that she actually is right (I do not have the training to figure it out) but the book almost read as a defense against anyone saying anything else. . It does not help much when she finds that Dart (who found the Taung child and interpreted the endocast) had written in his never published monograph some more details that are immediately announced as an agreement with her theory. Reading them, they are an agreement if someone already agrees with the theory; otherwise it is a case of reading a text in a way that may not necessarily be the way it was written... But besides these issues, the text is really interesting and informative, with a lot of details and observations that make this part of the book worth reading.And then the Flores bones show up and the attention is shifted to them. Because this time it is Falk and her team that will be the first to work on the brain and endocast of the new species (if it is a new species). And there follows a fascinating tale of science, rivalries, damaged bones (what kind of morons can damage this kind of unique bones and call themselves scientists) and a lot more brains. The almost sulking author from the first part of the book is gone and is replaced by the scientist that needs to defend a position (a jibe towards the science writers and their attempts to give equal time to all the theories is not missed of course) and that is trying to unearth the truth. And because she had worked on Taung as well, because the field she works in is pretty narrow, she can draw the parallels between previous discoveries and this one and to show how the story repeats itself. One wonders though - aren't the scientists falling into the "this happened before so it must be this way" trap... Another very valuable part of the book is the behind the scenes look of how these bones are excavated and what happens after that, of how the modern science work outside of the laboratories and of how unclear it is what had been really happening in the past (more than once, Falk explains how a certain fossil belongs to a species but half the scientists think something else). And then come the journal articles and responses, the protocols for discoveries announcement, all the information that someone that is not a scientist would not know. And then there is the accusation of a lie (called with a different name but...) against a team of scientists and the specimen search that is a lot more complicated than I would have thought. Falk uses the book to defend her hypothesis of what species the Flores bones are and where these small people came from (which is why scientists write books after all) but she does not just ignore the ones that disagree. A huge number of theories are tested and proved to be invalid - and the story of how and why is what makes most of the second part of the book. Of course at the moment the book cannot be finished. Noone really knows what the Flores bones are. It is even possible that the question will remain open for a very long time. But the simple fact of finding them had caused a huge stir in the sciences concerned with evolution and human origin and had made most of them reevaluate what they had believed. It is a book worth reading, even if in parts it gets way too technical. And the annoying parts just give character to the book - because despite all, the book achieves its objectives and puts two major fossils side to side and examines their influence on the science and the world as a whole.

ACKNOWLEDGMENTS
Much of this book was written while I was in residence during 2008–9 at the School for Advanced Research (SAR), in Santa Fe, New Mexico. There is nothing like getting up in the morning knowing that your only commitment is to work on your book. (Indeed, there were some cozy, snowy days when I did not get out of my pajamas.) For this privilege, I will be eternally thankful to the staff at SAR, including President James Brooks. Laura Holt obtained numerous esoteric references and helped with images, Jason S. Ordaz photographed specimens, and Jonathan Lewis spent countless hours shaping up the illustrations of endocasts. It was inspiring to live among several other resident scholars on the beautiful SAR campus. My next-door neighbor, Wenda Trevathan, finished her book on evolutionary medicine way ahead of the rest of us. We became close friends and will always remain so.
This project allowed me to do research in historical archives for the first time, and I loved getting lost in the details of Raymond Dart’s life. Dart (1893–1988) is famous for having discovered the world-renowned Taung fossil, which was the first recognized australopithecine. His unpublished manuscripts, notes, correspondence, and illustrations of Taung’s endocast, discussed in this book, are part of the holdings in the archives of the University of Witwatersrand (Wits), in Johannesburg, South Africa. I am deeply indebted to Dr. Goran Štrkalj for information about locating Dart’s papers in the Wits archives, to Lesego Phachane and Mack Mohale for access to and assistance in obtaining copies of these materials, to Wits for permission to reproduce Dart’s previously unpublished sketches, to Francis Thackeray for helping locate images of Taung and Dart, and to Kgomotso Mothate for going to a good deal of trouble to locate the historical image of Dart with Taung that is reproduced in this book.
Professor Phillip V. Tobias knew Dart well and eventually succeeded him as chair of the Anatomy Department at Wits. I am grateful to him for answering my questions and for providing reprints of his publications concerning not only the discovery of Taung but also the reasons why it took so long for scientists to acknowledge the validity and importance of Dart’s contributions. Peter Faugust provided assistance in assembling and mailing reprints. My insights from the unpublished papers of Dart were initially published in the 2009 Yearbook of Physical Anthropology, and I thank Bob Sussman (the editor) for making that possible.
I am especially grateful to Ron Clarke for helping me reexamine the Taung and other australopithecine specimens during my 2008 visit to Wits and for taking me to several important fossil hominin caves. It was a special thrill to descend deep within a cave at Sterkfontein to see the fabulous australopithecine skeleton known as Little Foot, which is still being excavated under Ron’s direction.
My analysis of Taung had to be placed within historical context, of course, which took me back to the early 1900s, when the awful Piltdown hoax was first perpetrated. The misconceptions about human evolution that were generated by Piltdown were widely accepted by scientists when Dart announced Taung in 1925. Partly because of this, it would be decades before the controversy surrounding Taung would be settled in Dart’s favor. As discussed in chapter 1, I believe that the Piltdown hoax, in turn, may have had earlier inspiration from the missing link
that was discovered in 1891 by Eugène Dubois—Pithecanthropus (now Homo) erectus. It was Pat Shipman’s fine book about Eugène Dubois, The Man Who Found the Missing Link, that got me thinking along these lines, and I thank her for providing clarification about the coconut story
surrounding the first discovery of a Pithecanthropus skullcap. I am also deeply grateful to Pat for taking the time to read a draft of this book and for providing numerous constructive suggestions. This book includes an image of John Cooke’s wonderful oil painting The Piltdown Committee, and I thank Richard Milner for helping me find it.
My gratitude to my colleagues from Mallinckrodt Institute of Radiology at Washington University School of Medicine in St. Louis knows no bounds. Fred Prior is head of the Electronic Radiology Laboratory, where I have collaborated for many years with him, Kirk Smith, and Charles (aka Scooter) Hildebolt on various projects related to brain evolution. As described in the second half of this book, Mallinckrodt is where the virtual endocast from Hobbit (LBI), the most complete specimen of Homo floresiensis, was first reconstructed, measured, and analyzed. That is also where it was compared with virtual endocasts from normal humans and human patients with microcephaly. The National Geographic Society (NGS) provided financial support for both of these projects. Our team enjoyed working with David Hamlin when he filmed part of his 2005 NGS television show about the discovery of Homo floresiensis (Tiny Humans: The Hobbits of Flores).
One of the most interesting features of LBI’s endocast is the unusual morphology of its frontal lobe. The pathbreaking neurological research of Katerina Semendeferi and her colleagues informed our interpretation of Hobbit’s endocast. Katerina also reviewed an earlier version of this book and provided numerous helpful suggestions, a time-consuming task, which I deeply appreciate.
Many people helped our work on Homo floresiensis move forward. First and foremost, my colleagues at Mallinckrodt and I will be eternally grateful to Mike Morwood, coleader of the team that discovered Homo floresiensis, for inviting us to analyze LBI’s endocast. It has been an incredibly exciting adventure. Officials from the Indonesian National Research Centre for Archaeology (ARKENAS) kindly permitted our access to the necessary data. We are indebted to our Indonesia collaborators Thomas Sutikna, Jatmiko, Rokhus Due Awe, and E. Wayhu Saptomo, without whom our research would never have been done. We had the pleasure of meeting them and visiting Flores because of an invitation extended to us by the late professor emeritus Teuku Jacob to attend the International Seminar on Southeast Asian Paleoanthropology in Yogyakarta, Java, in 2007.
Bill Jungers, who is deeply involved in studying the Flores remains, has been extremely tolerant of my never-ending requests for information and clarification related to Homo floresiensis. He has also provided some wonderful images for this book. Similarly, Mark Moore has patiently given feedback about the stone tools found on Flores and allowed me to reproduce a significant illustration that compares them with similar tools from Olduvai Gorge. Peter Schouten kindly allowed an image of his iconic reconstruction of a fleshed-out male hobbit to be included. An image of a wonderful reconstruction of Hobbit herself has been reproduced with the kind permission of Sebastien Plailly and paleo-artist Elisabeth Daynès. Bernard Zupfel provided the first photograph of Taung that graces the cover of this book, along with the photograph of Hobbit that was provided by Djuna Ivereigh. Kirk Smith provided the numerous images of virtual endocasts. I also thank Martin Young for preparing the skeleton keys graph and for the countless hours that he spent shaping up the other images, Yoel Rak for advice, and Donald Ortner for permitting inclusion of the photograph of a Swiss cretin.
Deirdre Mullane is my literary agent, and she’s the best! I am grateful to Blake Edgar, my editor at University of California Press, for his faith in this project and for his intelligent editing. His colleagues, Hannah Love, Lynn Meinhardt, and Cindy Fulton, were also enormously helpful, and Robin Whitaker did a terrific job on the copyediting.
Introduction
No subject provokes as much curiosity, argument, and dogma as the origin of humans. From the child who asks, Where did I come from?
to religious leaders who maintain traditional beliefs about creation and our role in the cosmos, human origins is a topic of keen concern. Most, if not all, cultures have origin stories. So do the scientists who study human evolution, which is one reason why our academic field, known as paleoanthropology, can be particularly acrimonious. This is nothing new. In the late nineteenth century, naturalists staunchly defended their particular theories about human origins, despite contradictory finds that were beginning to accumulate in the fossil record. In this book I focus on two pivotal and controversial discoveries that redefined how both the public and scientists viewed human evolution, one from the 1920s and another that was unearthed less than a decade ago. Each is analyzed within its contemporary milieu, including the state of scientific knowledge about human evolution, the social undercurrents related to religious fundamentalism, and the academic politics that pervade investigations of our past (paleopolitics). The two discoveries are compared with each other and interpreted within a wider framework that incorporates other finds, including the infamous Piltdown fraud. My aim is to portray the twists, turns, competitiveness, and passions that have always characterized research on human origins. If readers feel some of the excitement and drama of pursuing questions about what made us human and the thrill of refining the tentative answers in light of newly discovered fossils, I will have achieved my goal in this book. If they also glean something about scientists as people (warts and all) and the nature of their ongoing disputes with religious fundamentalists, all the better.
I have seen colleagues almost come to fisticuffs over clashing opinions, and my own ideas have been subjected to intense, sometimes unpleasant, scrutiny. The reason my work has drawn such attention is that I study the evolution of the human brain. Our brains, after all, set us apart from other animals; they are the physical locus of all of the cognitive, neurological, and emotional traits that make us human. I think this is why the subfield of paleoanthropology that focuses on brain evolution, called paleoneurology, is especially contentious.
Casts from the inner braincases of our ancestors (known as endo-casts) provide a physical record of this most important human organ and have been crucial for interpreting several fossils from the human family, including the two exceptional discoveries discussed in this book. The first, called Taung, was unearthed in South Africa by the Australian anatomist Raymond Dart in the 1920s and is probably the world’s most famous fossil. It consists of a little face, jaw, and endocast from a child and was the first specimen discovered from what is now recognized as an exceedingly important group of early human relatives, the australopithecines. The Taung specimen was announced in the journal Nature in 1925, just five months before the Scopes monkey trial would challenge the theory of evolution in Dayton, Tennessee. Although the announcement of Taung made headlines around the world, Dart was then subjected to over two decades of criticism from both religious fundamentalists and colleagues who doubted his claims about Taung’s importance for human origins.
Part of the suspicion about Taung was due to the prior discovery of the so-called Piltdown Man, which included a fossil skull from a quarry in England that seemed to provide important clues about the human past. The announcement of this find in 1912 captivated English scientists, who eagerly (some might say gleefully) claimed that humans had originated in the British Isles rather than elsewhere in Europe or Asia, as previously believed. Britain, it seemed, had just produced the most important evidence in the world for human evolution. Only decades later was Piltdown shown to be a forgery assembled from a human braincase and the lower jaw of an ape.
At the time, however, reputations of celebrated British paleoanthropologists were built on Piltdown, and they did not take kindly to one of their former junior colleagues upstaging their missing link with something very different from South Africa. The paleopolitics that Dart consequently experienced was intense and hurtful, and this book explores his personal and professional reactions, as well as the role of that controversy in shaping theories of human evolution. Much of the controversy about Taung focused on the small size and form of its endocast, which I have been privileged to study. In this book I will compare the still unresolved debate about Taung’s endocast with the one that raged when Dart first described it, and the results will be surprising.
The second extraordinary discovery comes from the island of Flores, in Indonesia, and was unearthed only a few years ago by a joint Australian-Indonesian team led by another Australian scientist, Michael Morwood, and a local expert, Raden Pandji Soejono. The find consisted of a relatively complete skeleton of an adult woman who stood a little over three feet tall—hence her nickname, Hobbit. Because nothing like her had ever been seen before, Hobbit was placed in a new species, Homo floresiensis. As with Taung, the legitimacy of Hobbit has been intensely controversial among scientists, some of whom claim she is not a new species but simply a modern human who was afflicted with disease.
Much of the controversy surrounding Hobbit has once again focused on the brain. I was part of the team that described Hobbit’s endocast, and my colleagues and I have used the latest CT-scanning technology to formulate our theories about her brain. Our findings have generated a good deal of discussion. In order to answer our opponents, my team has gone in unexpected new directions with our research, and the results reveal that the generally accepted model of human evolution may be in serious need of revision.
In my view, Hobbit is the most important hominin (or member of the fossil human family tree) to be discovered since Taung. In both cases, scientists were hostile to the claims of the discoverers because the implications of the specimens contradicted current scientific thinking. In this book I will examine why this was so and what impact such hostility had on the direction of science. Both discoveries proved to be highly controversial, not only among scientists, but also with the public. Both were thought to belong to species appearing in the wrong time and in the wrong place. Both possessed brains that were problematic because of their small sizes. Both hold important keys for understanding human evolution.
The British paleoanthropological establishment was clearly just as antagonistic toward Raymond Dart (one of their former students) as some scientists are today toward Michael Morwood and the researchers who study Homo floresiensis. The tone of the paleopolitics remains strikingly similar, negative, and at times ad hominem (trust me). This book contains my personal experiences related to controversies surrounding both discoveries and their implications for human brain evolution. It also reveals startling new information gleaned from Raymond Dart’s unpublished papers, which I examined in 2008, suggesting that more of a connection may exist between hobbits and australopithecines than anyone ever dreamed.
The same kind of politics that polarizes paleoanthropology because of divided opinions about the legitimacy of Hobbit delayed the acceptance of Taung for decades. Time and more remains of Homo floresiensis will determine whether Hobbit likewise becomes generally accepted as a pathbreaking discovery that casts an entirely new light on human origins. My bet is that it will.
ONE
Of Paleopolitics and Missing Links
The outstanding interest of the Piltdown skull is the confirmation it affords of the view that in the evolution of Man the brain led the way.
Grafton Elliot Smith
Shortly before Christmas 1912, a remarkable fragmentary skull was presented at a widely attended meeting of the Geological Society of London. The discovery had been made by Charles Dawson, a solicitor and an amateur geologist and archaeologist who had recovered seven pieces of the skull during the preceding four years from a gravel pit near Piltdown Common, in East Sussex. From 1913 to 1915, additional skull fragments appeared at Piltdown and two other nearby locations, including some from at least one other individual.
Because the unprecedented fossil appeared to be a missing link
that was intermediary between apes and humans, it was given a new scientific name, Eoanthropus dawsoni (Dawson’s dawn-man
), more commonly known as Piltdown Man.
The announcement caused great excitement among British scientists, who claimed that its antiquity proved that humans had originated in the British Isles. Piltdown had just become the most important site anywhere for studying the early evolution of humans.
It would be over four decades before the world would learn that Piltdown Man was a fraudulent specimen that had been assembled from a modern human braincase and the lower jaw of an orangutan and that both had been stained to appear as if they were from the same individual.¹ The most characteristic parts of the ape jaw, near the chin and farther back where it hinges with the skull, were missing, and the teeth had been deliberately filed to look more like those of humans. The gravel pit had also been salted with stone tools and fragments of fossilized hippopotamus, deer, horse, and mastodon from other places, which gave the false impression that the skull was very ancient.
But at the time, Piltdown Man seemed real. Even though potentially revealing features of the jaw were missing, what remained still looked significantly apelike. Anatomists had to reassemble fragments from the broken cranium and fill in the missing portions of the jaw in order to fit the pieces together. Some scientists favored a restoration that had a more apish jaw but with hinges that were humanlike enough to attach to the cranium. Others preferred to make the missing parts of the jaw appear more humanlike. Although the scientists argued heatedly about these details, all of the Piltdown restorations resulted in some combination of humanlike and apelike features. A mixture of traits, after all, was expected for a missing link.
Despite their quibbles over the skull’s details, most scholars embraced Piltdown as a legitimate human fossil—at least until 1953, when tests of the amount of nitrogen and fluorine in the Piltdown remains revealed that the cranium was older than the lower jaw.² This unleashed further investigations that eventually showed the extent of the fraud: There did not appear to be a single specimen in the entire Piltdown collection of hominoid bones, associated fauna, and cultural remains that had genuinely originated from Piltdown.
³ In hindsight and considering the seemingly ludicrous marriage of an orangutan mandible to a palpably modern human braincase,
the length of time it took for the hoax to be exposed was remarkably long. There were, however, understandable reasons why Piltdown had been accepted as an ancestor.
By the time of the Piltdown announcement, Charles Darwin’s general ideas about evolution had been published for slightly over half a century and had gained wide acceptance among scholars.⁴ Paleontologists were on the lookout for missing links that would support Darwin’s theories about human evolution, and several specimens had appeared as possible candidates. In 1891, the Dutch anatomist Eugène Dubois had discovered remains in Java that he christened Pithecanthropus erectus (ape-man upright,
now Homo erectus), or Java Man.⁵ The skullcap of this new species was not only small but also long, low, and thick, which made its potential role as a human forerunner highly contentious. Just three months before Piltdown was unveiled, Pithecanthropus was rejected as a human ancestor in a report to the International Congress of Anthropology and Prehistoric Archaeology in Geneva, by the influential French paleontologist Marcellin Boule, who echoed the earlier opinion of the German pathologist Rudolf Virchow by claiming it was nothing more than an extinct gibbon.⁶ While he was at it, Boule eliminated another potential human ancestor, the big-brained but primitive-looking Neanderthals from Europe, which he thought should be dropped entirely from the human family tree.⁷
Under these circumstances and despite disagreements about the details of Piltdown’s restoration, it is understandable that most of the leading scholars in British paleoanthropology eagerly accepted the discovery of a missing link from their very own gravel beds as the most important ever made in England, and of equal, if not of greater importance than any other yet made, either at home or abroad.
⁸ The main thing that convinced these scientists of Piltdown’s significance was its modern human braincase, because it fit better than the skulls of either Pithecanthropus or Neanderthal with prevailing expectations of how a very old missing link should look.
Having been personally embroiled in controversies surrounding the two hominins that are the focus of this book, I was nonetheless surprised to learn from the Piltdown episode that the passionate fights and acrimony that accompany the science of paleoanthropology are nothing new. Many of the paleoanthropologists who were players (or were played
) in the Piltdown episode were every bit as adamant and defensive about their favored evolutionary theories as some who practice in the field today. Another thing that may have been true then, as I believe it is now, is that the closer to the brain (or braincase) one’s prized specimen is, the more intense the debates about its interpretation. The brain makes us human, and the uniqueness of humanity has always been at the heart of the boisterous debates about human origins.
The disagreement between two leading scientists, Arthur Smith Woodward and Arthur Keith, about how to reconstruct Piltdown Man shows just how acrimonious these debates can be. Woodward had first crack, having been invited by Dawson to supervise the initial reconstruction and description of the fossil. Appropriately enough (since the mandible was from an orangutan), Woodward
