homosexuality can be found within any population of animal. the theory is that this occurs evolutionarily. without a homosexual population, the possibility of over-reproduction is too high, so in order to level it out populations will begin to form a group attracted to the same sex.

i identify myself as bisexual, but have yet to find a suitable theory as to why we exist. perhaps bisexuality is meant to create fractions in populations, as our piece of the population can either produce or not produce, so it would create a half, rather than a whole. i don't know, i'm a fucking english major.
