The study found that the genes for smell were something shared in friends but not genes for immunity . Why this similarity in olfactory genes is difficult to explain , for now . Perhaps , as the team suggests , if draws us to similar environments but there is more to it . There could be many mechanisms working in tandem that drive us in choosing genetically similar friends rather than“functional kinship” of being friends with benefits !One of the remarkable findings of the study was that the similar genes seem to be evolving faster than other genes .
