This holds primarily true for ''exclusive'' homosexuality (and less for bi-sexuality). | This holds primarily true for ''exclusive'' homosexuality (and less for bi-sexuality). | ||
However, male androphilia is likely more prevalent than what [[wikipedia:Mutation–selection balance|mutation–selection balance]] between androphilia and gynophilia (attraction women) would predict.<ref name="ref42">[https://www.bbc.com/news/magazine-26089486 http://www.bbc.com/news/magazine-26089486]</ref> | However, male androphilia is likely more prevalent than what [[wikipedia:Mutation–selection balance|mutation–selection balance]] between androphilia and gynophilia (attraction women) would predict.<ref name="ref42">[https://www.bbc.com/news/magazine-26089486 http://www.bbc.com/news/magazine-26089486]</ref> | ||

One can broadly distinguish ''slow'' and ''fast'' [[life history]] (LH) adaptations involving male androphilia, where fast LH means low investment in the offspring (a result of r-selection) and slow LH means high investment (a result of K-selection). Fast LH adaptations tend to be more violent, primitive, feral, accompanied by earlier maturation, lower cultural and social sophistication, higher [[sex drive]] and more [[promiscuity]]. | One can broadly distinguish ''slow'' and ''fast'' [[life history]] (LH) adaptations involving male androphilia, where fast LH means low investment in the offspring (a result of r-selection) and slow LH means high investment (a result of K-selection).
