Understanding Human Evolution

For the one-term course in human evolution, paleoanthropology, or fossil hominins taught at the junior/senior level in departments of anthropology or biology. This new edition provides a comprehensive overview to the field of paleoanthropology–the study of human evolution by analyzing fossil remains. It includes the latest fossil finds, attempts to place humans into the context of geological and biological change on the planet, and presents current controversies in an even-handed manner.

An authoritative account of human evolution, explaining the nature of the evidence and providing a new interpretation.

Describes how mapping the human genome has aided paleoanthropologists in their study of ancient bones used to explore human origins, from the earliest humans--bipedal apes--up to Martin Pickford's Millennium Man.

For the first time, the age-old questions of how and why humans evolved are explored from the perspectives of evolution, psychology, economics, and the Enneagram. The answers that emerge from this multidisciplinary approach provide new insights into the human condition, including the Nine Factors of Extinction, which were the behaviors responsible for multiple early human extinctions. And the Nine Human Virtues, which are the incumbent principles of modern human behavior. The answers to how and why humans evolved can be found in the depiction of each Enneatype. These depictions account for the Nine Human Endeavors (see front cover), which reveal how every human being is specifically adapted to eradicate one of the Nine Factors of Extinction, along with the specializations, functional adaptations, and general characteristics for each type. This information is indispensable for diagnosing the personality type of any human being. Perhaps most important is the discussion of the evolutionary purpose of every human being, and how that knowledge can be used for personal growth, in ways that are resolute, decisive, and transformative. When this knowledge is used constructively, the actuated potential of the individual is realized, along with the deeply personal meaning of life.

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.

Principles of Human Evolution presents an in-depth introduction to paleoanthropology and the study of human evolution. Focusing on the fundamentals of evolutionary theory and how these apply to ecological, molecular genetic, paleontological and archeological approaches to important questions in the field, this timely textbook will help students gain a perspective on human evolution in the context of modern biological thinking. The second edition of this successful text features the addition of Robert Foley, a leading researcher in Human Evolutionary Studies, to the writing team. Strong emphasis on evolutionary theory, ecology and behavior and scores of new examples reflect the latest evolutionary theories and recent archaeological finds. More than a simple update, the new edition is organized by issue rather than chronology, integrating behavior, adaptation and anatomy. A new design and new figure references make this edition more accessible for students and instructors. New author, Robert Foley – leading figure in Human Evolutionary Studies – joins the writing team. Dedicated website – www.blackwellpublishing.com/lewin – provides study resources and artwork downloadable for Powerpoint presentations. Beyond the Facts boxes – explore key scientific debates in greater depth. Margin Comments – indicate the key points in each section. Key Questions – review and test students’ knowledge of central chapter concepts and help focus the way a student approaches reading the text. New emphasis on ecological and behavioral evolution – in keeping with modern research. Fully up to date with recent fossil finds and interpretations; integration of genetic and paleoanthropological approaches.

Contributors from a range of disciplines consider the disconnect between human evolutionary studies and the rest of evolutionary biology. The study of human evolution often seems to rely on scenarios and received wisdom rather than theory and methodology, with each new fossil or molecular analysis interpreted as supporting evidence for the presumed lineage of human ancestry. We might wonder why we should pursue new inquiries if we already know the story. Is paleoanthropology an evolutionary science? Are analyses of human evolution biological? In this volume, contributors from disciplines that range from paleoanthropology to philosophy of science consider the disconnect between human evolutionary studies and the rest of evolutionary biology. All of the contributors reflect on their own research and its disciplinary context, considering how their fields of inquiry can move forward in new ways. The goal is to encourage a more multifaceted intellectual environment for the understanding of human evolution. Topics discussed include paleoanthropology's history of procedural idiosyncrasies; the role of mind and society in our evolutionary past; humans as large mammals rather than a special case; genomic analyses; computational approaches to phylogenetic reconstruction; descriptive morphology versus morphometrics; and integrating insights from archaeology into the interpretation of human fossils.
