Book Description
Where did we come from? What were our ancestors like? Why do we differ from other animals? How do scientists trace and construct our evolutionary history? The Evolution of Our Tribe: Hominini provides answers to these questions and more. The book explores the field of paleoanthropology past and present. Beginning over 65 million years ago, Welker traces the evolution of our species, the environments and selective forces that shaped our ancestors, their physical and cultural adaptations, and the people and places involved with their discovery and study. It is designed as a textbook for a course on Human Evolution but can also serve as an introductory text for relevant sections of courses in Biological or General Anthropology or general interest. It is both a comprehensive technical reference for relevant terms, theories, methods, and species and an overview of the people, places, and discoveries that have imbued paleoanthropology with such fascination, romance, and mystery.

Book Description
There are some issues in human paleontology that seem to be timeless. Most deal with the origin and early evolution of our own genus – something about which we should care. Some of these issues pertain to taxonomy and systematics. How many species of Homo were there in the Pliocene and Pleistocene? How do we identify the earliest members the genus Homo? If there is more than one Plio-Pleistocene species, how do they relate to one another, and where and when did they evolve? Other issues relate to questions about body size, proportions and the functional adaptations of the locomotor skeleton. When did the human postcranial “Bauplan” evolve, and for what reasons? What behaviors (and what behavioral limitations) can be inferred from the postcranial bones that have been attributed to Homo habilis and Homo erectus? Still other issues relate to growth, development and life history strategies, and the biological and archeological evidence for diet and behavior in early Homo. It is often argued that dietary change played an important role in the origin and early evolution of our genus, with stone tools opening up scavenging and hunting opportunities that would have added meat protein to the diet of Homo. Still other issues relate to the environmental and climatic context in which this genus evolved.

Book Description
The evolutionary path from the original primates to modern man is a long one and has taken many twists and turns, but naturally, as the fossil record grows, scientists gain a more complete understanding of our own mental and physical history in terms of genetics and anatomy. However, the correct order and relationships of the various specimen types are difficult to pin down. Many representative samples have been found in such minute amounts as to not preclude anomalies. They have been discovered in various stages of wear. Modern features did not occur simultaneously or uniformly, taking millions of years to become manifest in later types. Up to the present day's Homo sapiens, examples of the main types have been hybrids of older and more modern features. One of the earliest species of the genus Homo to be discovered is Homo habilis, which basically means "handy man." The name comes from the belief at the time of its discovery that this species was the first to start using stone tools. The first fossils to be uncovered in Olduvai Gorge were from the same stratigraphic layer as simple stone tools. Fossils of the crania and postcranial skeleton for this species have been found in both eastern and southern Africa and date to around 2.5-1.6 million years ago. Given the gradual changes that take place in evolution, Homo habilis shares a number of characteristics that are similar to the genus Australopithecus, such as in the postcranial elements. That said, the size and shape of the Homo habilis skull are markedly different. The size of the brain is much larger relative to the size of the body, being around 680 cc. In order to house a larger brain, the skull features a more vertical frontal bone, creating a more vertical forehead. The brow ridges that sit on the lower portion of the frontal bone are also reduced in size. Other reductions in the face include reduced prognathism and a reduction in the size of the premolars and molars. Postcranial elements display clear signs of bipedalism, such as the large toe being in line with the other toes instead being off to the side as they are in modern apes. Furthermore, the arches of the foot are present, allowing the full weight of the body to be supported and act as a shock absorber when walking. The leg bones are also longer than in Australopithecus, but Homo habilis retained long arms. Other primitive features include hand and finger bones that would have made climbing in the trees easier. The robustness of the finger bones is more comparable to those of modern apes than humans. There is also an attachment site present for a leg muscle that is particularly useful in climbing, suggesting that there was still some amount of time spent climbing. There is a wide variation of traits found in this species, and given the fragmentary nature of some of the elements, it is possible that they belong to other species of Homo like Homo rudolfensis. Another possibility is that sexual dimorphism was more pronounced in Homo habilis than previously thought. What is generally accepted is that Homo habilis was capable of making stone tools. These tools were flakes that were broken off from a core and had sharp edges. These tools could serve a number of purposes, such as cutting up the remains of an animal or cleaning its skin. But while Homo habilis almost certainly used tools, scholars still debate which species of Homo actually began making stone tools first since the species Homo rudolfensis also lived during the same time.

Book Description
This fourth volume marks the definitive publication of the most important fossil finds in palaeoanthropology: Olduvai hominids 7. 13, 16 and 24 (popularly known to workers in the field as Jonny's Child, Cindy, George and Twiggy). Found from 1960 in Olduvai Gorge and dating from 1.9 to 1.6 million years ago, they were identified in 1964 by Louis Leakey and the author amidst great controversy as a hitherto unrecognised species of the genus Homo, named by then Homo habilis on account of its apparent tool-making abilities. Professor Tobias develops this conclusion through extensive analysis of the cranial and endocranial material and teeth and comparison with a treasury of data, much of its original, on early hominds from South and East Africa, Asia and Europe, as well as modern human and anthropoid ape specimens. He offers a substantial exploration of the place of Homo habilis in human evolution, its status in relation to the australopithecines and Homo erectus and its apparent capacity for spoken language, which he sees as the key to the staggering enlargement of the human brain over the last two million years.

Book Description
How can we know about the lives of our ancestors who lived 30,000, or 300,000, or 3 million years ago? In The Extraordinary Story of Human Origins, Piero and Alberto Angela address the many difficulties and challenges that scientists face in assembling the record of human evolution. To piece together the intriguing puzzle of human origins it is necessary to study all clues that are made available by multidisciplinary research, including paleontology, biochemistry, geology, genetics, physics, and climatology. Like so many Sherlock Holmeses, researchers seek all possible clues and analyze them meticuously in hopes of being able to reconstruct the past. These pieces are few and fragmentary, ranging from the footprints left in volcanic ash 3.7 million years ago by hominids who walked exactly as we do, to a "Y" pattern on molars and mitchondrial DNA. But they all provide information on the diet, diseases, hunting techniques, and art of Australopithecus, Homo habilis, Homo erectus, the Neanderthal, and the first Homo sapiens sapiens. Written in an accessible but authoritative style, this study includes many lively reconstructions of the everyday life of our earliest ancestors based on the most reliable data. The Extraordinary Story of Human Origins makes available to a wide audience a unique look inside the exciting world of research into the the beginnings of human life on earth.
