We’ve come a long way since the fundamental structure of DNA was discovered by James Watson and Francis Crick. Nowadays, DNA sequencing can already tell us a lot about our ancestors—but now, a new technique developed by an international team of scientists allows them to pinpoint a person’s geographical origin—going back 1,000 years.
The Geographic Population Structure (GPS) tool exceeds previous best attempts to tie location to DNA. It has been reported that it can track populations back to the islands or villages they descend from, with a 98 percent success rate, compared to within about 500 miles for old methods.
