Science Can Use DNA GPS To Determine Where Your Ancestors Lived 1000 Years Ago

Maybe everything you know about yourself is a LIE.


Most of us can trace our lineage back a few generations, but what about way back? Like, would-need-a-TARDIS-to-determine-the-truth back? Two scientists have collaborated to create a new kind of DNA GPS that can accurately pinpoint where in the world you came from, over a thousand years ago.

Called the “Geographic Population Structure” tool (because, you know, GPS – hey, SHIELD and SWORD did it first), Dr. Eran Elhaik from the University of Sheffield and Dr. Tatiana Tararinova from USC can use it to determine the exact island or village from whence you came with a 98% success rate.

The GPS reads something called your “genetic admixture,” which is a reading of how many different gene pools you carry in your DNA (specifically, in this case, in your autosomal chromosomes). The GPS knows over 100,00 of these ancestry-informative markers that are specific to particular geographic regions, and can tell where you’re from based on what mixture you have.
