In 2021, a review of the current evidence infers from the timings provided by DNA studies that the dog was domesticated in Siberia 23,000 years ago by ancient North Siberians. The dog later dispersed from Siberia with the migration of peoples eastwards into the Americas and westwards across Eurasia. The ancient North Siberians were once a people whose ancestors archaeological remains have been found at the Paleolithic Yana RHS (Rhinoceros Horn Site) on the Yana River delta in arctic northern Siberia that is dated 31,600 YBP, and at the Mal’ta site near Lake Baikal in southern Siberia just north of Mongolia that is dated 24,000 YBP. Ancient dog remains dating to this time and place have yet to be discovered to support this hypothesis.
