Homosexual behaviour in one form or another has been observed and recorded in hundreds of different species for decades. But are the animals just going through some college-age "experimentation"? Or could there be some deeper, biological cause underlying their behaviour?
We explore some of the possible evolutionary arguments for the existence of a genetic component to homosexuality.
