curious?

Scientific.

My response was to a comment that many people naively raise: Homosexuality should be a reproductive dead end (for the individual), so it should net decrease reproductive success (of the closely related genes, ie family). So how can it persist in a population?

The answer appears to be that homosexuality is correlated with higher reproductive success. It is not causative, its correlated.

The correlation has been known for a long time, but only very recently have some links to actual mechanisms been described. I'm sure much more research will occur in the future.

Which to me raises a VERY interesting question. If something like the mother's immune response to male fetuses is eventually shown to be causative, then a "cure" will likely be developed, i.e. a drug treatment program for pregnant women with male fetuses. Which assuming success would eventually decrease the gay population. Which would then have the very interesting result that the unique contributions that gay men have made to humanity would start to fade away going forward. I think its incontrovertible that gay men excel in certain areas, primarily artistic related fields. What does society lose if we lose their talents? But who could blame parents not wanting to spare their child a life which even in the modern world is a more difficult life, primarily because of the bigots in society?

The same question will apply perhaps even more profoundly wrt to Autism Spectrum Disorder, if a cure for that is ever developed. Again, what parent wouldn't take the precaution of protecting their baby from that? But make a list of all the Nobel prizes that have been from the Aspy end of that spectrum, and ask yourself how different the world would be today, but for the individuals who have had that condition, and as a result, although some aspects of their life were certainly much tougher on them, they made immense contributions to human knowledge.

The unintended consequences of curing things will be interesting.

>> "Better than normal reproductive success." Curious way to frame simply having had lots of kids.

WHICH kind of leads back to the original question....

"Better than normal reproductive success." Curious way to frame simply having had lots of kids. FWIW.

Almost, but not quite. Reproductive success is measured by having kids who reproduce themselves. Having lots of kids is often a factor, but if they all die in childhood or don't have children themselves for other reasons, then it is a failure.
