Trace your 1000-year-old ancestry

Now a computer algorithm can trace your geographical ancestors all the way back to 1000 years ago.

To all those who want to trace their geographical origins, the news comes as a welcome move. A scientist has claimed that it is now possible to identify a person's ancestors, right down to the region or village, by analysing their DNA.

The test works by measuring the degree of genetic ?admixture? with a person?s DNA, caused when two previously separated populations begin to interbreed.

The scientist, Eran Elhaik of the University of Sheffield, has claimed that he has invented a computer algorithm that can analyse the variation in a person?s DNA and make accurate predictions about the location in the world where their ancestors had lived up to 1,000 years ago.

According to Elhaik, the test is based on comparing a person's DNA with genetic variations of populations that are known to be linked with specific areas of the world. From this, it is possible to infer a person?s ancestral origins to within a few miles, he said.

The test makes it possible to know where your DNA was formed up to 1,000 years ago, not where you were born. It makes it possible to accurately locate the village where your ancestors lived or what part of the world your DNA originated.
