Good let people be happy.
Yeah, I wonder how long it will keep rising or what the "actual" numbers are in society if they face no discrimination.
We likely will never know the "actual" numbers because it's a moving target.
Homosexuality is thought to be linked to higher fecundity of all the female relatives. As birth rates decline, a slightly higher fecundity will drive an increase in observed homosexuality/bisexuality as a percentage of the population.
Do you have any source for this? I have never heard about this before..
From a population genetics standpoint, the amount of homosexuality around is a puzzle. Because homosexual individuals have negative fitness (aka they don't make many babies), they should be very rare if it's genetically linked. There has to be a counter-benefit to the genetic family to maintain them in the population.
Why it's important: If there is no counter-benefit, then homosexuality logically has no significant genetic component. It's all environmentally influenced.
Original study proposing the concept in for homosexual mens families.
