Page 1 of 14 28 THE MYSTERIOUS BIPED JUST BEFORE CHRISTMAS 1887, a young Dutch doctor with an un-Dutch name, Marie Eugène François Thomas Dubois, arrived in Sumatra, in the Dutch East Indies, with the intention of finding the earliest human 1 remains on Earth. Several things were extraordinary about this. To begin with, no one had ever gone looking for ancient human bones before. Everything that had been found to this point had been found accidentally, and nothing in Dubois’s background suggested that he was the ideal candidate to make the process intentional. He was an anatomist by training with no background in paleontology. Nor was there any special reason to suppose that the East Indies would hold early human remains. Logic dictated that if ancient people were to be found at all, it would be on a large and long-populated landmass, not in the comparative fastness of an archipelago. Dubois was driven to the East Indies on nothing stronger than a hunch, the availability of employment, and the knowledge that Sumatra was full of caves, the environment in which most of the important hominid fossils had so far been found. What is most extraordinary in all this—nearly miraculous, really—is that he found what he was looking for. At the time Dubois conceived his plan to search for a missing link, the human fossil record consisted of very little: five incomplete Neandertal skeletons, one partial jawbone of uncertain provenance, and a half-dozen ice-age humans recently found by railway workers in a cave at a cliff called Cro-Magnon near Les Eyzies, France. Of the Neandertal specimens, the best preserved was sitting unremarked on a shelf in London. It had been found by workers blasting rock from a quarry in Gibraltar in 1848, so its preservation was a wonder, but unfortunately no one yet appreciated what it was. After being briefly described at a meeting of the Gibraltar Scientific Society, it had been sent to the Hunterian Museum in London, where it remained undisturbed but for an occasional light dusting for over half a century. The first formal description of it wasn’t written until 1907, and then by a geologist named William Sollas “with only a passing competency in anatomy.” So instead the name and credit for the discovery of the first early humans went to the Neander Valley in Germany—not unfittingly, as it happens, for by uncanny coincidence Neander in Greek means “new man.” There in 1856 workmen at another quarry, in a cliff face overlooking the Düssel River, found some curious- looking bones, which they passed to a local schoolteacher, knowing he had an interest in all things natural. To his great credit the teacher, Johann Karl Fuhlrott, saw that he had some new type of human, though quite what it was, and how special, would be matters of dispute for some time. Many people refused to accept that the Neandertal bones were ancient at all. August Mayer, a professor at the University of Bonn and a man of influence, insisted that the bones were 1 Though Dutch, Dubois was from Eijsden, a town bordering the French-speaking part of Belgium. Page 2 of 14 merely those of a Mongolian Cossack soldier who had been wounded while fighting in Germany in 1814 and had crawled into the cave to die. Hearing of this, T. H. Huxley in England drily observed how remarkable it was that the soldier, though mortally wounded, had climbed sixty feet up a cliff, divested himself of his clothing and personal effects, sealed the cave opening, and buried himself under two feet of soil. Another anthropologist, puzzling over the Neandertal’s heavy brow ridge, suggested that it was the result of long- term frowning arising from a poorly healed forearm fracture. (In their eagerness to reject the idea of earlier humans, authorities were often willing to embrace the most singular possibilities. At about the time that Dubois was setting out for Sumatra, a skeleton found in Périgueux was confidently declared to be that of an Eskimo. Quite what an ancient Eskimo was doing in southwest France was never comfortably explained. It was actually an early Cro-Magnon.) It was against this background that Dubois began his search for ancient human bones. He did no digging himself, but instead used fifty convicts lent by the Dutch authorities. For a year they worked on Sumatra, then transferred to Java. And there in 1891, Dubois—or rather his team, for Dubois himself seldom visited the sites—found a section of ancient human cranium now known as the Trinil skullcap. Though only part of a skull, it showed that the owner had had distinctly nonhuman features but a much larger brain than any ape. Dubois called it Anthropithecus erectus (later changed for technical reasons to Pithecanthropus erectus) and declared it the missing link between apes and humans. It quickly became popularized as “Java Man.” Today we know it as Homo erectus. The next year Dubois’s workers found a virtually complete thighbone that looked surprisingly modern. In fact, many anthropologists think itis modern, and has nothing to do with Java Man. If it is an erectus bone, it is unlike any other found since. Nonetheless Dubois used the thighbone to deduce—correctly, as it turned out—that Pithecanthropus walked upright. He also produced, with nothing but a scrap of cranium and one tooth, a model of the complete skull, which also proved uncannily accurate. In 1895, Dubois returned to Europe, expecting a triumphal reception. In fact, he met nearly the opposite reaction. Most scientists disliked both his conclusions and the arrogant manner in which he presented them. The skullcap, they said, was that of an ape, probably a gibbon, and not of any early human. Hoping to bolster his case, in 1897 Dubois allowed a respected anatomist from the University of Strasbourg, Gustav Schwalbe, to make a cast of the skullcap. To Dubois’s dismay, Schwalbe thereupon produced a monograph that received far more sympathetic attention than anything Dubois had written and followed with a lecture tour in which he was celebrated nearly as warmly as if he had dug up the skull himself. Appalled and embittered, Dubois withdrew into an undistinguished position as a professor of geology at the University of Amsterdam and for the next two decades refused to let anyone examine his precious fossils again. He died in 1940 an unhappy man. Meanwhile, and half a world away, in late 1924 Raymond Dart, the Australian-born head of anatomy at the University of the Witwatersrand in Johannesburg, was sent a small but remarkably complete skull of a child, with an intact face, a lower jaw, and what is known as an endocast—a natural cast of the brain—from a limestone quarry on the edge of the Kalahari Desert at a dusty spot called Taung. Dart could see at once that the Taung skull was not of a Homo erectus like Dubois’s Java Man, but from an earlier, more apelike creature. He placed its age at two million years and dubbed it Australopithecus africanus, or “southern ape man of Africa.” In a report to Nature, Dart called the Taung remains “amazingly human” and Page 3 of 14 suggested the need for an entirely new family, Homo simiadae (“the man-apes”), to accommodate the find.

Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D-preserved vertebrate brains are not known from the fossil record, so brain endocasts often serve as proxies. Recent work on extant birds shows that the Wulst and optic lobe faithfully represent the size of their underlying brain structures, both of which are involved in avian visual pathways. The endocasts of seven extinct birds were generated from microCT scans of their skulls to add to an existing sample of endocasts of extant birds, and the surface areas of their Wulsts and optic lobes were measured. A phylogenetic prediction method based on Bayesian inference was used to calculate the volumes of the brain structures of these extinct birds based on the surface areas of their overlying endocast structures. This analysis resulted in hyperpallium volumes of five of these extinct birds and optic tectum volumes of all seven extinct birds.

Laboratoire de Génétique Humaine et d'Anthropologie, Faculté de Pharmacie, 5000 Monastir, Tunisia. E.mail: [email protected] Abstract - In spite of important anthropological data stored up to date, the recent human evolution is still a subject of great controversy. Here I present a revision of the definition of modern man and an attempt to estimate the date of his emergence. The anatomical feature criterion cannot be considered as a rigorous criterion for identified modern human fossils from those of earlier Homo peoples. This identification could be carried out indirectly from analysis of cultural products and, if possible, directly by ancient DNA analysis. During the last 20,000 years period, Homo peoples have shown a first real cultural progress, which reflects their possession of the superior level of potential intellectual aptitude that marks the definition of modern man. On the basis of this definition, in agreement with several anthropological basic data, I consider that the real modern man, Homo sapiens sapiens, emerged at about 20,000 years ago.

Thus in order that they may not remain as eternal demons with a selfish nature, God send them out clothed in skin and to live of their own using their brains and learning to live. Since outside of Eden, the law of entropy was the default law, they are no susceptible to death. God had his plan of redemption without violating the freedom of any of his children. Until all creation is redeemed, since creation is always part of God himself with whole universe within God as the only reality is God, God himself will be in torment and pain. Yet that is what having children mean - even on earth.

Early Members of the Genus Homo Bonnie Yoshida-Levine Ph.D., Grossmont College Learning Objectives • Describe how early Pleistocene climate change influenced the evolution of the genus Homo. • Identify the characteristics that define the genus Homo. • Describe the skeletal anatomy of Homo habilis and Homo erectus based on the fossil evidence. • Assess opposing points of view about how early Homo should be classified. Describe what is known about the adaptive strategies of early members of the Homo genus, including tool technologies, diet, migration patterns, and other behavioral trends.The boy was no older than 9 when he perished by the swampy shores of the lake. After death, his slender, long-limbed body sank into the mud of the lake shallows. His bones fossilized and lay undisturbed for 1.5 million years. In the 1980s, fossil hunter Kimoya Kimeu, working on the western shore of Lake Turkana, Kenya, glimpsed a dark colored piece of bone eroding in a hillside. This small skull fragment led to the discovery of what is arguably the world’s most complete early hominin fossil—a youth identified as a member of the species Homo erectus. Now known as Nariokotome Boy, after the nearby lake village, the skeleton has provided a wealth of information about the early evolution of our own genus, Homo (see Figure 10.1).

  • The Dates of the Discovery of the First Peking Man Fossil Teeth
    The Dates of the Discovery of the First Peking Man Fossil Teeth Qian WANG,LiSUN, and Jan Ove R. EBBESTAD ABSTRACT Four teeth of Peking Man from Zhoukoudian, excavated by Otto Zdansky in 1921 and 1923 and currently housed in the Museum of Evolution at Uppsala University, are among the most treasured finds in palaeoanthropology, not only because of their scientific value but also for their important historical and cultural significance. It is generally acknowledged that the first fossil evidence of Peking Man was two teeth unearthed by Zdansky during his excavations at Zhoukoudian in 1921 and 1923. However, the exact dates and details of their collection and identification have been documented inconsistently in the literature. We reexamine this matter and find that, due to incompleteness and ambiguity of early documentation of the discovery of the first Peking Man teeth, the facts surrounding their collection and identification remain uncertain. Had Zdansky documented and revealed his findings on the earliest occasion, the early history of Zhoukoudian and discoveries of first Peking Man fossils would have been more precisely known and the development of the field of palaeoanthropology in early twentieth century China would have been different. KEYWORDS: Peking Man, Zhoukoudian, tooth, Uppsala University. INTRODUCTION FOUR FOSSIL TEETH IDENTIFIED AS COMING FROM PEKING MAN were excavated by palaeontologist Otto Zdansky in 1921 and 1923 from Zhoukoudian deposits. They have been housed in the Museum of Evolution at Uppsala University in Sweden ever since. These four teeth are among the most treasured finds in palaeoanthropology, not only because of their scientific value but also for their historical and cultural significance.

  • On the Paleontology of Animal Cognition: Using the Brain Dimensions of Modern Birds to Characterize Maniraptor Cognition
    12 Journal of Advanced Neuroscience Research, Special Issue, May-2017, 12-19 On the Paleontology of Animal Cognition: Using the Brain Dimensions of Modern Birds to Characterize Maniraptor Cognition Thomas M. Gaetano1, Margaret M. Yacobucci1 and Verner P. Bingman2,* 1Department of Geology, Bowling Green State University, Ohio, USA 2Department of Psychology and J.P. Scott Center for Neuroscience, Mind and Behavior, Bowling Green State University, Ohio, USA Abstract: Drawing inferences on the characteristics, including behavior, of extinct species using comparisons with extant species has a long tradition in paleontology. Departing from the observation that extinct maniraptors possessed brains with a relatively long and narrow telencephalon, we used digital endocasts taken from 11 species of modern birds to determine if any of the sampled modern bird species displayed a similar telencephalic shape, and by inference, similar cognitive ability. The analysis revealed that the telencephalon of the double-crested cormorant (Phalacrocorax auritus) is extraordinarily narrow (large length-to-width ratio) and strikingly similar to Archaeopteryx and even some non-avian, maniraptoran dinosaurs. The relatively narrow brain in turn suggests a relatively small nidopallium subdivision of the telencephalon and associated impoverished general cognitive ability. This first-order brain-anatomical observation, together with the relatively ancient origins of a cormorant fossil record, suggest that cormorants could be used as a model for the general cognitive abilities of extinct maniraptors. Keywords: Brain endocasts, Comparative cognition, Double-crested cormorant, Hippocampus, Nidopallium, Paleoneurology.
