Inspired by the wonder of his own experiences as a parent, former psychoanalyst and New York Times best-selling author Jeffrey Masson offers a remarkable look at one of the most fulfilling roles in the animal world: fatherhood. In The Evolution of Fatherhood, he examines the extraordinary behavior of outstanding fathers, heroes among animals, including: the male emperor penguin, who incubates the egg of his young through Antarctic blizzards; prairie dog dads, who teach their pups to play; the South American tamarin monkey, who "coaches" his mate through labor and delivery; and the wolf—and why wolves make good fathers, whereas their close relatives, dogs, don't. With captivating writing and impeccable research, Masson celebrates the unique and often surprising role that males play in the lives of their young.

Masson also looks at nature's worst fathers: lions, langurs, bears—and humans. He shows that when a father cares for his young, as does the beaver, we immediately look for a biological, and not an emotional, explanation. But Masson demonstrates that for these animals fatherhood is a profound, all-encompassing experience. Compelling and inspirational, The Evolution of Fatherhood is a book that will forever change our perceptions of parenthood and family love.
