The map of the human genome has shown that the DNA of human populations across the globe is a continuum, not bluntly divided as had been erroneously supposed. That means that each race's DNA blurs into the others because humans have the same ancestors, groups of people who left the African continent between 40,000 and 60,000 years ago. The genes that are obviously different between races include those that enabled each population to adapt to new latitudes; the ones that maximised our success in particular environments, and protected us from the diseases that we were exposed to.
SHOOT: I'm sure there are, however it may be wise to balance these benefits against cultural side effects, such as stigma, racism, phobias etc which may harm the child if not physically, psychologically and finally, economically. You should read this article regarding the analysis of Brazil's favelas, the slum areas. The 'kicker' is that stress levels in slums and affluent areas are the same, but the affluent people are almost all of homogeneous european origin, and the flavelas are based on mixed race. This tends to confirm the powerful social resistance to mixed-race, which is based on culture rather than on efficacy, or biological factors.
Look how sweet the little girl is directly below.
But the combination of inbreeding being bad and diversity being good has flung open the doors for another claim about what it means to be mixed-race. The idea sounds simple enough. If inbreeding is bad, then the opposite – outbreeding – should be good. It makes sense, some suggest, that people might be genetically better off if they were mixed race. The anecdotal evidence is writ large in the over-representation of Britain's tiny mixed-race population in the arts, music, modelling and sport. Mixed-race people account for 30 per cent of the current England football team in a country where they make up only 2 per cent of the general population.
So are these differences significant and, more to the point, are they significant enough so that when they are brought together, there might be tangible benefits for people who are mixed-race?
