No 'failed' mutations? Tell that to the victim of one. Idiotic claim snyper...<quoted text>
You've arrived at the crux of the issue.
Mutation does not equal "mistake", even when it's a "failed" mutation.
Just as Epigenetics doesn't follow quite the same coarse rules as Darwinism, "purpose" may need to be viewed in term of complex social systems to be discerned.
You're aware of the work that was done examining the social, economic and sexual support functions provided by gay orientation in a variety of cultures.
Consider for a moment the subtle biological processes among many species that maintain and adjust the male-female ratio. This cannot be explained in standard genetics, but when combined with endocrinology and epigenetics answers begin to appear.
Moreover, you are denying the point of the article. Epi-markers are mistakenly left, resulting in a confused, bsterile orientation.
You then make the ridiculous claim that that results in 'social, economic and sexual support functions'! You know those claims have been debunked.
