* | * '''Self-domestication''': It has been suggested in recent human history, human males have been substantially selected to be nice to one another (domestication), with homosociality being one instance thereof and in which homosexuality serves as a means of bonding via intimacy.<ref>https://www.frontiersin.org/articles/10.3389/fpsyg.2019.02955/full</ref> This largely overlaps with the notion of alliances in Muscarella's theory. | ||
* '''Helper in the nest''': This hypothesis claims that gay males tend to help in the household increasing the [[reproductive success]] of siblings,<ref name="ref42"></ref>, helping relatives to survive by allocating to them material resources, childcare, and protection being freed from the burden of caring for one's own offspring,<ref>Wilson, E.

Cambridge, MA: HarvardUniversity Press</ref> however homosexuals do not actually seem to exhibit more kinship behavior.<ref>https://www.researchgate.net/profile/J_Bailey2/publication/247233162_Is_male_homosexuality_maintained_via_kin_selection/links/5a09db03aca272d40f411b26/Is-male-homosexuality-maintained-via-kin-selection.pdf</ref> This also does not really explain bisexuality. Exclusive homosexuality is also rare, so this cannot be a strong selective pressure. | |||
