Episode notes

The question of o homosexual evolved is driven by the idea that thereis a clear dicotomy between homosexual and hetosexual, which is not clear. I think humans are pleasure seekers, d sexual creatures. And if these two things get mixed, you get pleasure seeking in other domains like male male relationships or female female relationships. The question of homosexuality evolved because it assumes some sort of genetic divide between homo and hetsexual man, with which no one has ever demonstrated.

What is gender? How different are men and women? Are differences due to biological sex or to culture? How do they compare with what is known about our fellow primates? Do apes also culturally learn their sex roles or is “gender” uniquely human?

Shermer and de Waal discuss: sex and gender in humans, primates, and mammals • who you identify as vs. who you’re attracted to • binary vs. nonbinary vs. continuum: how fuzzy can human sex categories be for a sexually reproducing species? • gender differences in physical and mental characteristics • why would homosexuality evolve? • chimpanzees and bonobos • what is the “purpose” of orgasms in women, nipples in men? • myths of the demure female • rape in humans and other primates: what is the purpose — sex, power or both? • murder, and human violence: how do men and women differ? • dominance and power • rivalry, friendship, competition and cooperation • maternal and paternal care of the young • same-sex sex • monogamy, polygamy, polyandry, etc. in humans, primates & mammals • grandmother hypothesis • primates & primatologists, humans & anthropologists: bias in science • the future of primates and primatology.
