Genome shows population movements due to climate.

Three approximately 31,000-year-old skulls from Dolni Věstonice in the Czech Republic. For the next 5,000 years, all samples analysed in this study—whether from Belgium, the Czech Republic, Austria, or Italy—are closely related, reflecting a population expansion associated with the Gravettian archaeological culture.
