UC Newswire Humans Brought Dogs to New World
: "Although New and Old World dogs are descended from the same Old World wolf ancestor, the DNA sequences from ancient American dogs are slightly different from their modern counterparts. 'Consequently, these data suggest Native American dogs have not genetically contributed to modern dog breeds,' Wayne said. 'DNA sequences from hundreds of dogs from dozens of modern breeds from throughout the world do not show traces of American ancestry. Native dogs may still have living descendants in some unsampled New World population, but their absence for a large sample of modern dogs reinforces the dramatic impact that the arrival of Europeans had on native cultures.'” More about this fascinating story about the relationship between man and dog. Europeans wiped out Native American dog species after they came to the New World.
