You might know where your forebears lived a few generations prior, but how about the exact village they came from — 1,000 years ago? Thanks to DNA sequencing, it’s now possible to find that out in many cases according to researchers from the University of Sheffield in the UK. The aptly-named GPS or Geographic Population Structure tool was modeled using more than 100,000 DNA signatures called AIMs (ancestry-informative markers). Since those are often typical to geographic regions, the researchers were able to pinpoint where subjects came from, even if they moved around later … During a Sardinian study, for instance, a quarter of the test subject were located to their exact villages and the remainder to within 31 miles.
