The effort to understand human nature in a political context is a daunting challenge that has been undertaken in a variety of ways and by a myriad of disciplines through the ages. From Plato to Hobbes and Burke, to Wallas and Oakeschott in our era, efforts have been made to provide some organic framework for the political study of mankind. What has added greatly to the complexity of the task is the increasing denial, even rejection, in the positivist and behaviorist traditions, of the very notion of a human nature. The work can be described as a series of interlocking propositions: the proverbial view of human nature can be explained by evolutionary theory. Biological differences between men and women are responsible for family, community and group life. Social evolution goes through stages which are recapitulated in the moral life of individuals. A well-defined federal system mirrors human development. And finally, for Fleming, most problems in social and political life stem from violations of this federalist system. Fleming's volume takes up a variety of issues: sex and gender differences, democracy and dictatorship, individual and familial patterns of association. He does so in the context of showing how forms of legitimate authority such as families, communities and nations establish such authority by appeals to human nature, and that these appeals, while presumably resting on empirical evidence, also confirm the existence of normative structures. Fleming's work is an effort of synthesis that is sure to arouse discussion and debate. It represents a serious addition to a literature retrieved from the historical dustbins to which it has been repeatedly consigned.

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.

A Science News Best Science Book of the Year: “A brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution.” —Agustín Fuentes, PhD, author of The Creative Spark: How Imagination Made Humans Exceptional Winner of the W.W. Howells Book Prize from the American Anthropological Association Blending history, science, and culture, this highly engaging evolutionary story explores how walking on two legs allowed humans to become the planet’s dominant species. Humans are the only mammals to walk on two rather than four legs—a locomotion known as bipedalism. We strive to be upstanding citizens, honor those who stand tall and proud, and take a stand against injustices. We follow in each other’s footsteps and celebrate a child’s beginning to walk. But why, and how, exactly, did we take our first steps? And at what cost? Bipedalism has its drawbacks: giving birth is more difficult and dangerous; our running speed is much slower than other animals; and we suffer a variety of ailments, from hernias to sinus problems. In First Steps, paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is. A seven-million-year journey to the very origins of the human lineage, this book shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities to our thirst for exploration and our use of language—and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. Includes photographs “A book that strides confidently across this complex terrain, laying out what we know about how walking works, who started doing it, and when.” —The New York Times Book Review “DeSilva makes a solid scientific case with an expert history of human and ape evolution.” —Kirkus Reviews “A brisk jaunt through the history of bipedalism . . . will leave readers both informed and uplifted.” —Publishers Weekly “Breezy popular science at its best.” —Science News

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.
