Answer:
Human sexual dimorphism
Step-by-step explanation:
Sexual dimorphism is a characteristic of certain species where the two sexes exhibit different characteristics that go beyond the differences in their sexual organs. The differences might include size, weight, colour, markings, behavioral and cognitive differences. In this passage, Carol Tavris argues that the natures of men and women are not different in any "universal" way. This seems to reject the idea of human sexual dimorphism.
