Material culture provides evidence for dog harnessing in the Arctic 9,000 YBP. Ancient DNA from the remains of these dog indicates that they belong to the same genetic lineage as modern Arctic dogs, and that this lineage gave rise to the earliest native American dogs. Since the earliest native American dogs, multiple, genetically different lineages of dogs were introduced by the Thule people and European settlers. The European dogs replaced the dog lineages that were introduced more than 10,000 years ago.
