Nine Principal Genetic Profiles of Western Eurasians
We frequently use these terms, so it is useful to understand what they refer to. Most of these genetic profiles appeared after the Last Glacial Maximum. Before the Glacial Maximum (approximately 20,000–26,000 years ago), Eurasia was inhabited by populations with different genetic profiles.
All of these genetic profiles ultimately share common origins and descend from a single ancestral population that has not yet been sampled in ancient DNA studies.
