ABSTRACT
Love makes the world go round, so the proverb goes. Perhaps, if love includes sex and reproduction. Certainly love is a strong drive, and probably universal. Anthropologist Helen Fisher indicates that at least 87 percent of the world’s cultures have a concept of romantic or passionate love. Biologist Robert Trivers postulated that males and females pursue and reject each other according to their needs to procreate. These needs differ in males and females, echoing past evolutionary designs for successful reproduction. Jealousy may be a primary reason for divorce, but having a different basis in males and females. Males, with their concern for paternity, express jealousy about the sexual behaviors of females; females are likely to show jealousy about the distribution of males’ resources. In the larger picture of reproduction men and women use signs of beauty as measures of reproductive potential.
