““We’ll show that human beings evolved in intimate groups where almost everything was shared—food, shelter, protection, child care, even sexual pleasure. We don’t argue that humans are natural-born Marxist hippies. Nor do we hold that romantic love was unknown or unimportant in prehistoric communities. But we’ll demonstrate that contemporary culture misrepresents the link between love and sex. With and without love, a casual sexuality was the norm for our prehistoric ancestors.””
