An international team of scientists has developed a process that allows them to pinpoint a person’s geographical origin going back 1,000 years. Known as the Geographic Population Structure (GPS) tool, the method is accurate enough to locate the village from which the subject’s ancestors came, and has significant implications for personalized medical treatment.
