"Titillating and provocative essays from one of the freshest voices in science today -- Why do testicles hang the way they do? Is there an adaptive function to the female orgasm? What does it feel like to want to kill yourself? Does "free will" really exist? And why is the penis shaped like that anyway? In Why Is the Penis Shaped Like That?, the research psychologist and award-winning columnist Jesse Bering features more than thirty of his most popular essays from Scientific American and Slate, as well as two new pieces, that take readers on a bold and captivating journey through some of the most taboo issues related to evolution and human behavior. Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins. With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you are interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come"--

Gossip is no trivial matter; despite its reputation, Epstein argues, it is an eternal and necessary human enterprise. Proving that he himself is a master of the art, Epstein serves up delightful mini-biographies of the Great Gossips of the Western World, along with many choice bits from his own experience. He also makes a powerful case that gossip has morphed from its old-fashioned best--clever, mocking, a great private pleasure--to a corrosive new-school version, thanks to the reach of the mass media and the Internet. Written in his trademark erudite and witty style, Gossip captures the complexity of this immensely entertaining subject.

Enslaved peoples were brought to the Americas from many places in Africa, but a large majority came from relatively few ethnic groups. Drawing on a wide range of materials in four languages as well as on her lifetime study of slave groups in the New World, Gwendolyn Midlo Hall explores the persistence of African ethnic identities among the enslaved over four hundred years of the Atlantic slave trade. Hall traces the linguistic, economic, and cultural ties shared by large numbers of enslaved Africans, showing that despite the fragmentation of the diaspora many ethnic groups retained enough cohesion to communicate and to transmit elements of their shared culture. Hall concludes that recognition of the survival and persistence of African ethnic identities can fundamentally reshape how people think about the emergence of identities among enslaved Africans and their descendants in the Americas, about the ways shared identity gave rise to resistance movements, and about the elements of common African ethnic traditions that influenced regional creole cultures throughout the Americas.

Contrary to common perception and belief, most island societies of the Pacific were not isolated, but were connected to other island societies by relations of kinship and marriage, trade and tribute, language and history. Using network models from graph theory the authors analyze the formation of island empires, dialect groups, economic and political centers; the evolution and devolution of social stratification; and the development of kinship terminologies, marriage systems and descent groups.
