In a major kick in the ball to all the bigots and homophobes out there , new scientific research has provide grounds that homosexual conduct may actually be controlled by certain genetic traits that bring solid benefits to the generative success of entire species .
Same - sexual practice sexual behavior ( SSB ) has been observed in a vast number of creature , tramp fromdolphins to Leo , although the purpose of this type of conduct has been the source of great confusion for quite some fourth dimension . After all , on the face of it , homosexual activity should have a negatively charged core on reproduction and selection rates .
Traditionally , scientists have tend to explain this behavior away as “ perception wrongdoing , ” whereby confuse animal somehow mistake members of their own sex for potential fellow . An alternative theory say that SSB occurs as a by - product of a firm libido . Clearly , the evolution of a healthy sexual appetite is idealistic for species survival , so this hypothesis essentially focus on on the idea that an overflow of luxuria causes some animals to mate with members of their own sex , suggesting that the costs associate with this behavior are outweighed by the benefits generated by this impregnable sex drive .
However , more late , investigator have begin to seek the underlyinggenetic basisof SSB , with some suggesting that the genes that stimulate these tendencies in one sex may at the same time increase the procreative prowess of the opposite sex of the same species .
The phenomenon whereby one factor influences multiple seemingly unrelated trait is known aspleiotropy , and an increasing body of evidence now points to the fact that this mechanics may somehow cause SSB .
To test this , a team of researcher from Uppsala University in Sweden conducted an experiment using seed beetles , which have been observed charter in SSB . According to their study , which appears in the journalBMC Evolutionary Biology , some male have even been found with “ entangled genitals , ” take for granted to be a result of same - sexual activity relation attack .

The team pick out those mallet that displayed the highest tendency for SSB in ordering to breed a credit line of gay insects that have a much great aptness for same - sex mounting than the mean mallet .
Interestingly , the research worker found that although the males of this line be given to pronto pursue in homosexual acts and therefore had reduced reproductive success , their distaff siblings were actually more prolific than those from other line , put down more eggs and producing more offspring .
found on this evidence , the study authors suggest homosexual bodily process among seed beetles is the result of “ widespread pleiotropy , ” resolve that “ SSB in one sex can come due to the expression of factor that carry benefit in the other sex . "
Study Colorado - author David Berger say IFLScience that while this watching suggest a “ genetic mechanism ” behind SSB in general , he “ would be cautious about extrapolating these result to apply to other animals , ” such as human . In other quarrel , the study does not suggest the genes associated with homosexual tendencies in masses are link up to birth rate rate in members of the opposite sex . However , the of the essence take - home substance of this research is that , given that pleiotropy is universal to all organisms , “ there ’s no reason why a genetical mechanism ” of this sort ca n’t live in humans too .
All in all , a read through the cogitation should be more than enough to shut up those who like to talk about homosexual demeanor as “ unnatural . ” Unfortunately , though , the multitude that tend to make those sort of remarks are n’t exactly famous for reading donnish journals .
