New research shows that dogs might have migrated to the United States around 10,000 years ago and it was thousands of years after the first human migrants reached North America. A team of researchers has analyzed the genetic characteristics of eighty four individual dogs. They came from over a dozen sites in North and South America. Researchers say that it was the largest ever analysis of ancient dogs.
Kelsey Witt is a graduate student at the University of Illinois and is also a co-author of the study. He said, “Dog genetic diversity in the Americas may date back to only about 10,000 years ago.”
