Everybody could have happily giggled the night away when Ryan dropped quips about "penguin poontang" and "fucking monkeys" but the underlying thesis in Sex at Dawn is no joke. In a nutshell, Ryan has surmised that humans are:
- not "naturally" monogamous, neither men nor women
- women are NOT the choosy, non-libidinous sex
- homosexuality is an integral part of human socialization, not just sexuality
- the status of virginity is entirely a construct of the Standard Narrative (patriarchal society)
- forced female fidelity has been the source of untold pain and suffering (see: stonings under Islam and nearly every Shakespeare play)
- a post-agrarian society that embraces polygamy is as socially stable as a three-legged chair
- homo sapiens are just as closely related to bonobos as we are to chimpanzees
It's not excessive promiscuity that sinks us as a species but the lack of it used to form and cement bonds.
Awfully good bedtime reading.
