University of Sheffield  have discovered a genesis analysis tool that scans subject’s DNA and estimates their ancestor’s origin 1000 years ago. This tool’s methodology involves identifying the genetic admixture, where by studying over 100,000 DNA signatures as a baseline, the tool approximates a subject’s genetic origins. Scientists claim that this tool is substantially more powerful compared to previous methods as it employs all 44 diploid autosomal chromosomes, and not just the two sex chromosomes.


The researchers carried out an experiment, wherein they tested residents of ten villages in Sardinia, to establish the effectiveness of the GPS. It was observed that almost 25% people were placed correctly in the first test, while the remaining population was scattered in less than 50 km range of their true origins. This technique was even used on people residing in 20 islands in Oceania, where the observation (based entirely on their DNA) was that 90% of the folks were on the right island.

The process is efficient enough to genetic admixture, which results from interbreeding between individuals from two or more separate populations. A new gene pool is thus formed by genetic admixture. These processes were very common during migrations and invasions. Dr. Eran Elhaik imagines different populations around the world as different colors of soup, to easily visualize genetic admixture. When the blue soup is mixed with the red soup, the offspring would eventually be a purple soup, he adds.

But this makes locating your DNA ancestry all the more difficult, for more soup mixture implies the introduction of more colors of soup. But the new GPS technique accurately pin-points the villages where a subject’s ancestors resided many years ago by tracing your DNA to 1000 years to its place of origin.
