According to a new study, scientists found out that dogs came to the Americas for the first time, only about 10,000 years ago.
It was indeed a very late arrival. The adorable dogs, touted to be the most loyal in the animal kingdom arrived in the Americas just about 10,000 years back; says the latest research. The results of this work got published online on Dec. 18 in the Journal of Human Evolution. According to the researchers, this observation may play significant role in order to carry out in depth analysis of human migration into the New World.
According to the report by Live Science; while carrying out this research, the scientists examined 42 new sample of DNA. All of them were obtained from ancient dog remains. The results were then compared with the similar number of DNA samples that were subsequently taken from the previous studies.
At the end of the study, the scientists came up with four completely new genetic signatures in the new samples, suggesting the unexpected existence of more diversity amongst the ancient dogs in the Americas.
The most interesting conclusion of this study was, the researchers reportedly said that it was just 10,000 years ago; dogs first arrived in the Americas.
According to the report by Live Science; study co-author Ripan Malhi, of the University of Illinois at Urbana-Champaign, said in a statement: This date “is about the same time as the oldest dog burial found in the Americas. This may not be a coincidence.” The scholars and researchers willing to know the nitty gritty of ancient migration processes have always counted on the long trusted association between human beings and dogs to achieve important insights.

The scientists, based on this recent finding, suggested that it is more likely that the dogs arrived in the Americas with the second wave of human migration, the one that took place thousands of years after people from Asia first reached to the Americas.
“Dogs are one of the earliest organisms to have migrated with humans to every continent, and I think that says a lot about the relationship dogs have had with humans,” lead study author Kelsey Witt, a biologist at the University of Illinois at Urbana-Champaign, said in a statement. “They can be a powerful tool when you’re looking at how human populations have moved around over time.”
