Amerindian colonization of Siberia
Around 20,000 B Amerindians migrated from China to Siberia, where they mixed with and replaced Native Siberians. The Amerindian and East Asian passage to America and Greenland was made possible by the colonization and replacement of Indigenous Siberians.
History
Siberia was first populated by Homo Sapiens around 45,000 B.[n] However around 20,000 B,[n] Amerindian colonials started to settle Siberia, locally replacing and extincting First Siberians. Approximately around 10,000 B,[n] Amerindians crossed walking the frozen Bering strait from Siberia to the Americas and created the first acknowledged human settlements, known as the Clovis culture.
Archaeogenetics

The First Siberian Nations, also known as Ancient North Eurasians (ANE), were genetically closer to Europeans than to East Asians or Amerindians. Indigenous Siberians survivors would later be one of the father groups of the Yamnaya people.
