The manuscript that appears in Nature Communications is the result of the framework of the Genographic Project (a project funded by National Geographic and IBM among others) with the participation of several international research groups, with the aim of unravelling human population history from genetic data. One of the research groups that participated in the project is the one leaded by David Comas from the Institut de Biologia Evolutiva (CSIC-Universitat Pompeu Fabra). The research that appears in Nature Communications has allowed the researchers the precise tracing (up to few hundred kilometres) the geographic origin of different individuals from diverse human populations using around hundred thousand genetic markers in a new chip. Up to now, the geolocalization from genetic data was performed mainly in European related populations due to the large amount of genetic information available in these populations. Thanks to these new chip and new algorithms this geolocalitzation has been applied to worldwide human populations. The advances in genetic geolocalization of worldwide populations open new challenges in the ancestrality tests, biomedical and forensic sciences and in cases of genetic privacy.
