| Research Abstract |
The purpose of this study is to examine social evolution of humans from their mating patterns and society systems by comparing the temporal distribution patterns of female estrus between baboons and chimpanzees. Both in chimpanzees and baboons, females asynchronized their estrous periods. One consequence of estrous asynchrony is male-biased operational sex ratio. There were three hypotheses for rising female fitness : increasing birth rate, patanity confusion, and rising sperm competition. I considered these three hypotheses by making a model.
