Buss, an evolutionary psychologist at the University of Texas, reveal: For men, the worst thing is that their partner is sleeping with others, and women are terrified of the idea that their partner falls in love someone else.
As a good evolutionist, Buss explains this difference with the hypothesis that jealousy is a strategy that prevents the loss of "important relationships ." And the risks are different for each sex.
The male can distribute his sperm, since he has to spare, but he must make sure that he is dedicating paternal care to his own genes; that is, that the child is his. The biological cost of the ovum is higher, so a woman has to be sure that the man she chooses as a partner will not abandon his responsibility in raising her to go away with a new love.
