Book Description
The inspiration for this volume of contributed papers stemmed from conversations between the editors in front of Chuck Hilton's poster on the determinants of hominid walking speed, presented at thel998 meetings of the American Association of Physical Anthropologists (AAPA). Earlier at those meetings, Jeff Meldrum (with Roshna Wunderlich) had presented an alternate interpretation of the Laetoli footprints based on evidence of midfoot flexibility. As the discussion ensued we found convergence on a number of ideas about the nature of the evolution of modem human walking. From the continuation of that dialogue grew the proposal for a symposium which we called From Biped to Strider: the Emergence of Modem Human Walking. The symposium was held as a session of the 69th annual meeting of the AAPA, held in San Antonio, Texas in 2000. It seemed to us that the study of human bipedalism had become overshadowed by theoften polarized debates over whether australo pithecines were wholly terrestrial in habit, or retained a significant degree of arboreality.

Book Description
The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it means to be human, including the origins of bipedalism; the emergence of our genus Homo; the first use of stone tools; increases in brain size; and the emergence of Homo sapiens, tools, and culture. The Earth's geological record suggests that some evolutionary events were coincident with substantial changes in African and Eurasian climate, raising the possibility that critical junctures in human evolution and behavioral development may have been affected by the environmental characteristics of the areas where hominins evolved. Understanding Climate's Change on Human Evolution explores the opportunities of using scientific research to improve our understanding of how climate may have helped shape our species. Improved climate records for specific regions will be required before it is possible to evaluate how critical resources for hominins, especially water and vegetation, would have been distributed on the landscape during key intervals of hominin history. Existing records contain substantial temporal gaps. The book's initiatives are presented in two major research themes: first, determining the impacts of climate change and climate variability on human evolution and dispersal; and second, integrating climate modeling, environmental records, and biotic responses. Understanding Climate's Change on Human Evolution suggests a new scientific program for international climate and human evolution studies that involve an exploration initiative to locate new fossil sites and to broaden the geographic and temporal sampling of the fossil and archeological record; a comprehensive and integrative scientific drilling program in lakes, lake bed outcrops, and ocean basins surrounding the regions where hominins evolved and a major investment in climate modeling experiments for key time intervals and regions that are critical to understanding human evolution.

Book Description
The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

Book Description
Australopithecus species have been the topic of much debate in palaeoanthropology since Raymond Dart described the first species, Australopithecus africanus, in 1925. This volume synthesizes the geological and paleontological context of the species in East and South Africa; covers individual sites, such as Dikika, Hadar, Sterkfontein, and Malapa; debates the alpha taxonomy of some of the species; and addresses questions regarding the movements of the species across the continent. Additional chapters discuss the genus in terms of sexual dimorphism, diet reconstruction using microwear and isotopic methodologies, postural and locomotor behavior, and ontogeny.

Book Description
What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditionsâ€"or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient lifeâ€"and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening othersâ€"including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative toolsâ€"and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

Book Description
Our ability to walk on two legs is not only a characteristic human trait but one of the things that made us human in the first place. Once our ancestors could walk on two legs, they began to do many of the things that apes cannot do: cross wide open spaces, manipulate complex tools, communicate with new signal systems, and light fires. Titled after the last two words of Darwin's Descent of Man and written by a leading scholar of human evolution, Lowly Origin is the first book to explain the sources and consequences of bipedalism to a broad audience. Along the way, it accounts for recent fossil discoveries that show us a still incomplete but much bushier family tree than most of us learned about in school. Jonathan Kingdon uses the very latest findings from ecology, biogeography, and paleontology to build a new and up-to-date account of how four-legged apes became two-legged hominins. He describes what it took to get up onto two legs as well as the protracted consequences of that step--some of which led straight to modern humans and others to very different bipeds. This allows him to make sense of recently unearthed evidence suggesting that no fewer than twenty species of humans and hominins have lived and become extinct. Following the evolution of two-legged creatures from our earliest lowly forebears to the present, Kingdon concludes with future options for the last surviving biped. A major new narrative of human evolution, Lowly Origin is the best available account of what it meant--and what it means--to walk on two feet.

Book Description
Chris Stringer's bestselling The Origin of our Species tackles the big questions in the ongoing debate about the beginnings of human life on earth. Do all humans originate from Africa? How did we spread across the globe? Are we separate from Neanderthals, or do some of us actually have their genes? When did humans become 'modern' - are traits such as art, technology, language, ritual and belief unique to us? Has human evolution stopped, or are we still evolving? Chris Stringer has been involved in much of the crucial research into the origins of humanity, and here he draws on a wealth of evidence - from fossils and archaeology to Charles Darwin's theories and the mysteries of ancient DNA - to reveal the definitive story of where we came from, how we lived, how we got here and who we are. 'A new way of defining us and our place in history' Sunday Times 'When it comes to human evolution Chris Stringer is as close to the horse's mouth as it gets ... The Origin of Our Species should be the one-stop source on the subject. Read it now' BBC Focus 'Britain's foremost expert on human evolution ... you need a primer to make sense of the story so far. Here is that book' Guardian 'Combines anecdote and speculation with crisp explanation of the latest science in the study of the first humans ... an engaging read' New Scientist Chris Stringer is Britain's foremost expert on human origins and works in the Department of Palaeontology at the Natural History Museum. He also currently directs the Ancient Human Occupation of Britain project, aimed at reconstructing the first detailed history of how and when Britain was occupied by early humans. His previous books include African Exodus- The Origins of Modern Humanity, The Complete World of Human Evolutionand most recently, Homo Britannicus, which was shortlisted for the Royal Society Science Book of the Year in 2007.
