Sex, Power, and Partisanship
How Evolutionary Science Makes Sense of Our Political Divide

An evolutionary psychologist traces the roots of political divisions back to our primate ancestors and male-dominated social hierarchies. Through the lens of evolutionary science, this book offers a novel perspective on why we hold our political ideas, and why they are so often in conflict. Drawing on examples from across the animal kingdom, clinical psychologist Hector A. Garcia reveals how even the most complex political processes can be influenced by our basic drives to survive and reproduce—including the policies we back, whether we are liberal or conservative, and whether we are inspired or repelled by the words of a president. The author demonstrates how our political orientations derive from an ancestral history of violent male competition, surprisingly influencing how we respond to issues as wide-ranging as affirmative action, women's rights, social welfare, abortion, foreign policy, and even global warming. Critically, the author shows us how our instinctive political tribalism can keep us from achieving stable, functioning societies, and offers solutions for rising above our ancestral past.
