Male, female

"Why do girls tend to earn better grades in school than boys? Why are men still far more likely than women to earn degrees in the fields of science, technology, engineering, and mathematics? And why are men on average more likely than women to be injured in accidents and fights? These and many other questions are the subject of both informal investigation in the media and formal investigation in academic and scientific circles." "In his landmark book Male, Female: The Evolution of Human Sex Differences, author David C. Geary provided the first comprehensive evolutionary model to explain human sex differences. Using the principles of sexual selection such as female choice and male-male competition, Geary systematically reviewed and discussed the evolution of sex differences and their expression throughout the animal kingdom, as a means of explaining the same process in Homo sapiens." "Now, over 10 years since the first edition, Geary has completed a massive update, expansion, and theoretical revision of his classic text. New findings in brain and genetic research inform a wealth of new material, including a new chapter on sex differences in patterns of life history development; expanded coverage of genetic research; fatherhood in humans; cross-cultural patterns of sex differences in choosing and competing for mates; and genetic, hormonal, and socio-cultural influences on the expression of sex differences. Finally, through his motivation to control framework, Geary presents a theoretical bridge linking parenting, mate choices, and competition with children's development and sex differences in brain and cognition. The result is an even better book than the original - a lively and nuanced application of Darwin's insight to help explain our heritage and our place in the natural world."--Jacket.
