Do all dog breeds really have some wolf DNA in them? New scientific study has answers
Those tiny, fluffy dogs walking down the street may look cute, but beware – they probably have some wolf in them. Almost two-thirds of all dog breeds do!
That is the discovery announced this week by scientists, who were surprised to find that nearly two-thirds of all dog breeds have a detectable amount of wolf DNA.
And it is not genetic leftovers from when dogs originally evolved from wolves around 20,000 years ago, but instead suggests that domesticated dogs and wild wolves have interbred within the last few thousand years.
This does not mean that "wolves are coming into your house and mixing it up with your pet dog," Logan Kistler, a curator at the Smithsonian Museum of Natural History and co-author of a new study, told AFP.
It also seems to have influenced the size, smelling power, and even personality of modern dog breeds, the scientists said.
