A groundbreaking exploration of the history of genetics reveals the controversial debate between two rival scientists. Gregory Radick challenges the dominant narrative, revealing how Mendelian ideas triumphed not because of their accuracy, but due to political and scientific factors. A must-read for anyone interested in the history of science and the future of genetics.

The New York Times bestselling author of The Hormone Cure and The Hormone Reset Diet shows every woman how to create a lifestyle that will help her look great, feel energized, and slow down the effects of aging.

Journalist Libby Copeland explores the culture of genealogy buffs, the science of DNA, and the business of companies like Ancestry and 23andMe, all while tracing the story of one woman, her unusual results, and a relentless methodical drive for answers that becomes a thoroughly modern genetic detective story.

Drawing on such diverse antecedents as history, myth, and religion, as well as modern developments in biology and genetics, the author bravely questions and rejects the reigning scientific orthodoxy and shows how humans and apes may have had a common upright ancestor—an upright ape that walked on two legs much as we do now.
