- Ford and Beach 1952
- 76 non-US societies
- 2/3 Consider homosexual as normal or acceptable
Causes of Homosexuality
DARWINIAN
- Heterosexuality is morphogenetic
- Polymorphous sexuality
- Natural selection
- Heterosexuality and its variations
- Support: Homosexuality observed in different species: Bull, cow, stallion, donkey, cat, ram, goat, pig, antelope, elephant, hyena, monkey, ape, rabbit, lion, porcupine, hamster, mice, porpoise, lizard, bird……
GENETIC

- Kolb 1963 ®
7 MZ not concordant
- Heston & Field 1968 ®
5 MZ, only 2 concordant
- Pillard & Weinrich 1985 ®
