@crisw I’ve seen that theory as an explanation for why homosexuality persists. However, it’s not clear to me how it works. The alpha person would want to reproduce, but they would also carry a gene that appears in some of their progeny which suppresses their desire or need to reproduce?
I suppose. The non-reproduction gene could be activated in certain circumstances—say famine, or too many other children, but not be activated during times of plenty.
However, in this case, it would appear that celibacy is a choice, instead of something being determined by a genetic predisposition. It might be influence by beliefs or personal preferences. It would be interesting to see if celibate people are randomly distributed around the world or if it is correlated with some other factors.
