THE EVOLUTNARY PARADOX OF HOMOSEXUALYBEG GAY NO LONGER HOLDS THE STIGMA ONCE DID, BUT EVOLUTN, WHY DO A NON-REPRODUCTIVE TRA PERSIST?TOM WHIPPLEPUBLISHED: MAY 8, 2018 AT 11:00 PMTHE EVOLUTNARY PARADOX OF HOMOSEXUALY

Here we discs a body of scientific evince that directly ntradicts this assertn and stead argu that homosexualy has emerged through evolutn as a normal variant that nfers survival benefs to the fay, particularly certa settgs. In the largt and most rigoro geic lkage study foced on this topic, Sanrs and lleagu sctized the DNA om 409 pairs of gay brothers, searchg for shared sgle nucleoti polymorphisms (SNPs)—substutns of a sgle letter the geic (Sanrs, 2015).

Androphilia—strong sexual attractn to mal—has been proposed as a geilly termed tra that when hered by a woman creas the number of children she will bear, but when hered by a male will predispose to homosexualy. Studi show that mothers of gay men are much more likely to have skewed X-activatn than mothers who had no gay sons, another strong ditn that male homosexualy is a partially herable ndn, and gen on the X-chromosome are likely to be volved termg sexual orientatn mal. Compellg evince dit that epigeic mechanisms are fundamental to the genis of homosexualy, which helps expla both s partially herable nature and the -utero environmental effects that seem to predispose a male to same-sex orientatn.

Although the creased odds may seem outsized, they are relative to a basele rate of homosexualy of about two percent for a first son; the probabily of havg a gay son reach fifty percent only after ten olr blogil brothers.
