Q

How is human the size of human testes when compared to gorillas and chimpanzees?

A

Human are in the middle. (females at least some of the time would reproduce with multiple males )
-> in primate species where females mate with more the testes tend to be bigger relative to body size.
EX: Gorilla - there is no threat, so there is no need to produce as much sperm

Q

Why is it that humans females can no longer visible be seen as impregnable? (you can’t tell when a female is ovulating)

Women who engage in unrestricted mating behave as if they were a species where males aren’t involved in child-rearing

43
Q

In what way does timing predict unrestricted mating?

Life-cycle - increasingly unrestricted behavior approach around age 35 (Pregnancies after 35 have increased risks)
