A group of scientists from the University of Illinois have been observing and examining the remains of ancient dogs discovered in both South and North America. By the analysis, they made various genetic proofs to imply that dogs may have been into existence thousands of years after the humans first started to inhabit America.
Lead study researcher Kelsey Witt comments, “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.” The University of Illinois graduate student, along with anthropology professor Ripan Malhi, continues, “They can be a powerful tool when you’re looking at how human populations have moved around over time.”
Researchers came to know that dogs have a relation to humans which dates way back-even more than in we thought it’d be in the history. Scientists were examining the mitochondrial DNA to find answers such as maybe the previous notions were incorrect, the notions which said that dogs maybe arrived in alaska some 20,000 to 40,000 years back. The new research, however, says that might even be as recent as 10,000 years ago.
Once the dogs learned to live with humans, they found that it was a great benefit to them, not solely due to the food, but also that humans offer access to more food sources and also a sense of security due to a pack of diverse creatures in it.
The remains also reveal four new genetic signature which means not only did the dogs made an isolated migration to the Americas, but also the genetic diversity may been much more diverse than we originally presumed it to be.
