What is Mother Nature: Maternal Instincts and How They Shape the Human Species about?

"Mother Nature presents a radical new way of understanding how mothers act and why, and how this new understanding is changing the way scientists think about how evolution works."--BOOK JACKET.

"Drawing on anthropology, history, literature, developmental psychology, and animal behavior, Sarah Hrdy examines the distinct biological and genetic elements that constitute maternal instinct.

She strips away the biases implicit in conventional stereotypes of female nature to give us very different and provocative perspectives on maternal ambivalence, the links between maternity and ambition, mother love and sexual love, and she explains why age-old tensions between the sexes persist and are being played out today in efforts to control women's reproductive choices."--BOOK JACKET.

A glimpse inside

Illustration for Mother Nature: Maternal Instincts and How They Shape the Human Species
Maternal Instinct Is Not Unconditional

Hrdy dismantles the popular notion that mothers are always self-sacrificing and nurturing. Drawing on cross-cultural anthropology and primate studies, she shows that maternal behavior is shaped by evolutionary trade-offs and context. Mothers make difficult decisions—sometimes even about the survival of their own offspring—based on resources, social support, and future reproductive opportunities. This perspective reframes maternal love as both powerful and pragmatically adaptive, not simply automatic or unconditional.

Ambivalence and Agency in Motherhood

Rather than seeing maternal ambivalence as a flaw, Hrdy argues it is a natural and expected part of motherhood. Mothers often face conflicting drives: to nurture, to survive, to invest in some offspring over others. This ambivalence is not a moral failing but an evolved response to complex social and ecological pressures. By recognizing maternal agency, Hrdy gives mothers credit for the difficult decisions they navigate, moving beyond simplistic ideals of selfless devotion.
