An Ancient Dog Bone Could Be Evidence of the Route Humans Took to North America

Prior to the brand-new research study, “the oldest American pet remains were found from mid-continent sites, not recommending how they got there,” she said, but this latest discovery “supports that our coastal pet is a descendant of dogs that took part in this initial migration along the Northwest Pacific Coast. We do know, though, that this dog was a domesticate and not a wolf, and if I were a pet dog, I would most likely remain around human beings for food.

Prior to the new research study, “the earliest American canine stays were discovered from mid-continent sites, not recommending how they got there,” she stated, but this most current discovery “supports that our coastal dog is a descendant of pets that participated in this initial migration along the Northwest Pacific Coast.
