Homosexuality Can Be Genetically Turned On & Off

The real scientific breakthrough will occur when they find the gene that controls canine tibiaphilia - the propensity of certain dogs to have sex with the lower halves of human legs. While some analysts have attributed this to random limb humping, the experimental data show a definite correlation (confidence factor of p = 0.95) for canine sexual intercourse with male human legs. While tibiaphilia has not been frequently noted in humans, this might well be due to the dearth of research into this important area of hominid behavior. I'm sure Prof. Jugglenuts can enlighten us about this affectation and will not just regress to a "love the shin, hate the shinner" position.

The mandate of evolution is not reproduction but the perpetuation of the genome. Reproduction (sexual or otherwise) is one part of this but an equally important part is for a species to not exhaust its resources. Various species have developed a variety of strategies to accomplish this, including varying sex (i. e., male to female) ratios, limiting reproduction to certain "alpha" male and female members of the pack, and perhaps to genetically induce homosexuality into a portion of the population when stressing resources is a more eminent threat than is decimation of the species. The human species does not appear at the present time to be threatened with bottlenecking or annihilation, but there are some early indications that the population density has reach the point where resources are being stressed.
