The current Europeans are the descendants of the people who created the civilizations. In summary, the CHG are a key line of Eurasian genetic heritage, along with the WHG and EF. They formed a separate branch (they separated while still in the Paleolithic), maintained continuity in the Caucasus area, and in younger eras their genes fed into the cavernous population and spread to other European groups and the peoples of Central and South Asia. These results underscore the formative influence of the Caucasus on the genetics of Europeans and Asians.
