Scottish scientists have found a way to identify a person’s family roots to within a few miles, raising the possibility that city dwellers could soon trace their descendants back to their ancestral village.
The team analysed the genetics of unrelated people who had four grandparents from the same village on Scottish islands, three Italian alpine villages and two in Croatia. This resulting data was fed into a computer, which then decided which town each of the people came from based on their genetics.
It predicted the correct village of origin for 100% of the Italian sample, 96% of the Scottish sample and 89% of the Croatian sample.
