How we choose—and lose—our mates has always been a source of fascination. This controversial book is the first to present a unified theory of human mating behavior. The Evolution of Desire is based on the most massive study of human mating ever undertaken, encompassing more than 10,000 peoples of all ages from thirty-seven cultures worldwide. If we all want love, why is there so much conflict in our most cherished relationships? To answer this question, we must look into our evolutionary past, according to David M. Buss. For in attracting, keeping, and even breaking up with our mates, we are closer to our ancestral forebears than many of us think.
