This might be the weirdest thread I've ever started.

So, after my first impression (which was to be weirded out), I got to thinking about this interesting phenomenon happening in Japan. Methuselah theory, as I understand it, relates the population growth to the growth in our ability to provide resources. When the growth in population is too much greater than the growth in population, there is some population reducing event (plague, famine, or war). However, this theory deals with the changes in population and not with size of the population itself.
The reason I bring this up is I wonder if this is an evolutionary "brake" that limits the size of the population. I'm not trying to discuss the morality of the issue. However, this entire spew of what Spinoza would call "little grey cells" lead me to ask the same thing about homosexuality. Obvious there are social issues involved as well, but...
...might homosexuality be an overpopulation safety net?
I've read about studies on this, but I was unable to find a good link.
Thoughts?
