If evolution were a person, that person would an asshole. That person is literally Hitler. More than ten thousand Hitlers! Evolution wants us to be “adaptive” and “fit”, but why should I want that? Why should I want evolutionary adaptability? At best, evolutionary adaptability aligns with my interests, and at worst, adaptability amounts to cooperation with an evil and uncaring god.
So when someone suggests that being asexual or GLB isn’t evolutionarily adaptive, my response is “So what?”
It’s plausible that GLB traits come with some evolutionary adaptability, but there are plenty of conditions for which this is far less plausible. Lots of disabilities for instance. My boyfriend suffers from epilepsy. The evolutionary value of seizures is found wanting. Educated epileptics everywhere must find peace with the fact that they are not evolutionary winners. Which is fine, because evolution is an asshole.
Yes it’s plausible that GLB traits have slight evolutionary adaptability. For instance, there is the hypothesis that GLB make up for the lack of children by caring for their nieces and nephews. But I’m skeptical; you’d have to have a lot of additional surviving niblings to make up for not having children.
I think it’s more likely that GLB traits are just not sufficiently maladaptive to overcome genetic drift. Probably because GLB people were strongly encouraged to have children regardless of their gender preferences. Alternatively, GLB traits are correlated with other adaptive traits (known as pleiotropy). One basic hypothesis is that the genes that cause men to find men attractive might also cause women with the same gene to find men attractive. An evolutionary biologist I know suggested that maybe there are just a lot of different points of mutation that can cause GLBA traits.
But all that discussion of possible adaptability is not relevant to me. I am not forced to have biological children, I am not caring for nephews, and I am not my own sister. I am an evolutionary dead end. Which is fine because evolution is an asshole. Evolution is an old relative who is always pressuring me to have children even though I’m out to them.
