Nature's Law of Compensation?
We all know about Nature's Law of Compensation, and those who study Newtonian Physics would see it expressed in one of the Three Laws of Motion. We also see it very active in biology, where cell mutations occur to counter the effect of disease (eg. Sickle Cell Anaemia). So, is it so far-fetched to think that the occurrence of homosexuality, might be a natural population-control mechanism?
