Population differences in susceptibility to AIDS: an evolutionary analysis.

Previously we have reported population differences in sexual restraint such that, higher socio-economic status greater than lower socio-economic status, and Mongoloids greater than Caucasoids greater than Negroids. This ordering was predicted from a gene-based evolutionary theory of r/K reproductive strategies in which a trade-off occurs between gamete production and social behaviors such as intelligence, law-abidingness, and parental care. Here we consider the implications of these analyses for sexual dysfunction, including susceptibility to AIDS. We conclude that relative to Caucasians, populations of Asian ancestry are inclined to a greater frequency of inhibitory disorders such as low sexual excitement and premature ejaculation and to a lower frequency of sexually transmitted diseases including AIDS, while populations of African ancestry are inclined to a greater frequency of uninhibited disorders such as rape and unintended pregnancy and to more sexually transmitted diseases including AIDS.
