Document Summary
When reproductive opportunities are unequal between the sexes. When one sex is controlling reproductive opportunities --> other sex will try to open opportunities. With more opportunities --> more reproductive success --> genes passed on. Both the clitoris and penis originate from the same tissue. If bathed in androgen --> lengthen and turn into a shaft, penis. If not --> remains short and stubby and turns into a clitoris. In social pact, it"s better to have less and maintain good relations. Immigrant males need to be a little more aggressive to improve social status. Females in social pact will usually be lactating. When females is pregnant --> pseudopenis could be made because when females are in development they are in "male hormone" high concentration. When giving birth, like a football going through a straw. Many times the mom and the pups both die. Adaptive value does not need to be adaptive in every case.
