The Nature of Nurture book cover

The Nature of Nurture

Rethinking Why and How Childhood Adversity Shapes Development

A Darwinian reinterpretation of childhood adversity, arguing that many behaviors labeled “maladaptive” are strategic adaptations.

“The Nature of Nurture brilliantly unravels the mysteries of why and how early adversity matters—not just psychologically, but biologically. In doing so, Jay Belsky deftly dismantles the age-old nature-nurture dichotomy.”
—Dalton Conley Author of The Social Genome
