Barbara Natterson-Horowitz and Kathryn Bowers, an evolutionary biologist and science journalist, respectively, taught us a lot about animals, humans, and the diseases we share in their groundbreaking Zoobiquity. Again skirting the twin dangers of anthropomorphism—making animals too much like us—and anthopodenialism—missing the connections between us and animals—their new work looks at how both animals and humans experience adolescence. Shared by nearly all species, from insects and amphibians to birds and mammals, adolescence, or, as the authors term this pivotal developmental stage, Wildhood (Scribner, $28), is crucial to helping the young develop skill sets concerning safety, status, sexuality, and independence. Examining each life lesson in detail, the book tracks the experiences of a juvenile penguin leaving her Antarctic birthplace for the treacherous seas; a young male hyena, born at the low-end of his species’s totem pole; the complicated romantic history of a humpback whale; and a wolf who has to go off and survive on his own. Full of fascinating details about these four species and many others, these coming-of-age stories also bear profound similarities to those of their human counterparts. If teens seem maddeningly reckless, over-sensitive, and obsessed with status, this book shows that they are only behaving as evolution prepared them to.
