The Dangerous Passion: Why Jealousy is Necessary in Love and Sex

If you think that jealousy is simply a neurosis or merely a manifestation of insecurity, then reading David Buss's The Dangerous Passion may change your opinion. Buss asserts that jealousy is an adaptive behavior, albeit an imperfect one, which helped our human ancestors cope with reproductive threats. Buss uses examples from insect and primate populations, as well as Hollywood, to help illustrate the evolutionary concepts discussed. Building on his previous book, The Evolution of Desire, on the gender differences in mate selection, Buss argues for a coevolutionary cycle based on concealment and detection (jealousy) between the genders in their drive to optimize reproductive success.

Although pathological aspects of jealousy--battering, stalking, and killing--are argued to be the result of adaptive responses, they are in no way defended as acceptable or natural behavior. Buss indicates that it is his hope that by understanding the forces that shaped jealousy we can better cope with its effects--positive or negative. --Irwin S. Hirsh
