Vienna, Austria: New light has been thrown on how humans choose their partners, a scientist will tell the annual conference of the European Society of Human Genetics today (Monday May 25). Professor Maria da Graça Bicalho, head of the Immunogenetics and Histocompatibility Laboratory at the University of Parana, Brazil, says that her research had shown that people with diverse major histocompatibility complexes (MHCs) were more likely to choose each other as mates than those whose MHCs were similar, and that this was likely to be an evolutionary strategy to ensure healthy reproduction.
So, let’s include MHC analysis for all the online compatibility checking services online. If their MHCs are too close, that is a big red ‘X’. Far enough apart and they get to be a couple.
Of course, if humans normally detect this by smell, then couldn’t someone figure out what the sources are and include them in the latest version of Axe anti-perspirant? Someone could surreptitiously find out what a potential partner’s MHCs are and then use the appropriate deodorant to attract them. This opens up so many business opportunities.
