We re told that what men and women desire from relationship is different he s looking for novelty, she s looking for commitment; he s concerned with looks, she s concerned with status.

We re told that we live in a hierarchy of romantic inequality where some are 10s and others are 2s; where some people are marriage material and others are wired for promiscuity.

But this narrative is unscientific.

Such ideas have their roots in a branch of science called evolutionary psychology, and over the past few decades its ideas have permeated our culture and fuelled a narrative that inspires despair and anxiety and, in its most extreme form, these ideas have been hijacked in the service of misogyny and violence.

But the truth about human attraction and the way evolution plays out in our romantic lives is much more interesting and optimistic.

Bonded by Evolution offers a radical new picture of the roots of enduring chemistry. Distilling evolutionary biology, anthropology and psychology and informed by his pathbreaking research and original experiments at the Attraction and Relationships Research Laboratory in California, psychology professor Paul Eastwick reveals how attraction is best depicted as a process of finding and, often, creating a compatible relationship.

Once we understand how ancestral humans sought compatible partners in small networks, we can build a clearer and brighter picture of how attraction, sex and relationships really work.
