In its place, I suggested a five-sex system. Researchers studied the genes on the sex-specific chromosomes of three species of snakes, including the five-pacer viper (left), the pygmy rattlesnake (center) and the mountain garter snake (right) for clues about the forces that shaped their evolution. In her article, “The Five Sexes: Why Male and Female are not Enough,” Anne Fausto-Sterling outlines her reasons and arguments concerning why the two socially and medically accepted (dominant) gender identities are not sufficient in identifying the genders of every individual.
