Ancestry Surprises From New Genetics Analysis Method

An anonymous reader commends a recently published study involving a new way to analyze genetic variation in human populations (full article published in PLOS Genetics): "[S]cientists from Ireland, the UK and the US analysed 2,540 genetic markers in the DNA of almost 1,000 people from around the world whose genetic material had been collected by the Human Genome Diversity Project. The results include a number of surprises... the Yakut people of northern Siberia were found to have received a significant genetic contribution from the population of the Orkney Islands, which lie off the coast of Scotland... there must have been a period of gene flow from northern Europe to east Asia. The study also shed light on the peopling of the Americas, as the results suggest that the native populations of north and south America have different origins."

Re:So "Native Americans" were invaders?

[kripkenstein]

So what does this mean for Native Americans? They were aggressive immigrants who displaced the original population? Essentially all human populations are/were aggressive invaders at some point. See Jared Diamond's writings, for example, about how the Bantu came to occupy most of Africa, how the Han Chinese did the same for China, etc., etc.

We see things as they are right now, and just presume that the clock was frozen before the last few centuries. So, we see black people in Africa and Chinese people in China and assume they were always there. They weren't, they displaced someone to get there. It's just been forgotten.

Not that this makes any of it 'right' or 'justified', nor does it make it 'wrong' or 'unjustified'. These are the facts. Make of them what you will.
