Ancient Dogs in the Americas (image) University of Illinois at Urbana-Champaign Share Print E-Mail Caption A new study adds to the evidence that dogs were domesticated before first migrating to the Americas. The dogs' history parallels that of ancient humans who migrated from North Asia to North America, dispersed throughout the Americas and suffered major population declines upon contact with European colonists. Dots represent sites from which the bones of ancient dogs were collected for the new analysis and the relative ages of the bones.
