Step-by-step explanation:
Some of the most compelling evidence against a strong biological determination of gender roles comes from anthropologists, whose work on preindustrial societies demonstrates some striking gender variation from one culture to another. This variation underscores the impact of culture on how females and males think and behave.
Margaret Mead (1935) was one of the first anthropologists to study cultural differences in gender. In New Guinea she found three tribes—the Arapesh, the Mundugumor, and the Tchambuli—whose gender roles differed dramatically. In the Arapesh both sexes were gentle and nurturing. Both women and men spent much time with their children in a loving way and exhibited what we would normally call maternal behavior. In the Arapesh, then, different gender roles did not exist, and in fact, both sexes conformed to what Americans would normally call the female gender role.
