Not Exactly Rocket Science : European genes mirror European geography
ommitment » European genes mirror European geography Category: Genetics Posted on: September 1, 2008 8:00 AM, by Ed Yong Within a drop of blood, you can find all the information you need to reasonably guess where a person came from, without ever having to look at their face, name or passport. Small variations in our DNA are enough for the task. They can be used to pinpoint someone's place of origin to a remarkable degree of accuracy, often to within a few hundred kilometres. The new discovery comes from a team of Swiss and American researchers led by John Novembre at UCLA, who wanted to understand how the human genome varies on a continental scale. To that end, they looked at the genomes of over 1.300 people sampled from almost three dozen countries across Europe. The sample was originally collected by GlaxoSmithKline to hunt out genetic variations that influence the effectiveness of drugs and their side effects, but Novembre's team put it to use in understanding the links between genes and geography instead. They analysed at single-letter differences in DNA ("single nucleotide polymorphisms" or SNPs) at about 200,000 places in each of the genomes. They compared this data to each person's country of origin as well as that of their grandparents if possible.
