Think About This

Think about this: There is more genetic similarity between an Australian aboriginie and a Northern European than there is between most people of different tribes in Africa. How can that be?

Well, about 70,000 years ago, one group made it out of Africa (with their relative lack of genetic diversity), and they populated the rest of the world. They probably used a “beachcomber” route and moved along the coast of India then island-hopped to Australia. Sometime later, a subsetĀ of these folks moved north into Europe and Asia.


So there is more genetic difference between a San tribesman and a Bantu than there is between a Norwegian and a Papua New Guinean. All humans are ~99.9% genetically the same, and of that small 0.1 per cent difference, 94 per cent of the variation is among individuals from the same populations, and only six per cent is between individuals from different populations.


It’s amazing how easy it is to become xenophobic about people who don’t look like us. It’s good to remember – we’re all cousins!
