Previously, scientists have only been able to locate where your DNA
was formed to within 700kms, which in Europe could be two countries
away; however this pioneering technique has been 98 per cent
successful in locating worldwide populations to their right geographic
regions, and down to their village and island of origin.

"What is remarkable is that, we can do this so accurately that we can
locate the village where your ancestors lived hundreds and hundreds of
years ago -- until now this has never been possible."

To demonstrate how accurate GPS predictions are, Dr Elhaik and his
colleagues analysed data from 10 villages in Sardinia and over 20
islands in Oceania. The research published today in the journal Nature
Communications shows that Dr Elhaik and his team were able to place a
quarter of the residents in Sardinia directly to their home village
and most of the remaining residents within 50km of their village. The
results for Oceania were no less impressive with almost 90 per cent
success of tracing islanders exactly to their island.
