They may be man’s best friend, but new research indicates that dogs arrived in the Americas thousands of years after humans did.
According to a recent study, dogs only came to the region about 10,000 years ago, NBC News reports.
Researchers arrived at this conclusion by testing 42 D.N.A. samples taken from taken from ancient dog remains and comparing it with the same number of samples from previous studies. Their findings indicate canines came to the continent with a second wave of human migration, long after humans had initially settled in the New World.
The study’s lead author Kelsey Witt said in a statement that dogs were one of the earliest species to accompany human migration to every continent. “They can be a powerful tool when you’re looking at how human populations have moved around over time,” she said.
