I love genetics and DNA. 🙂 I had learned all the 30 yrs or more of wolf/dog theories, only to have them squashed by DNA. Learn new things.. I'm good with that.

On wolves btw... our current wolves are not the ancient wolves dogs came from:
Wolves provide no clarity. Grey wolves used to live across the entire Northern Hemisphere, so they could have potentially been domesticated anywhere within that vast range (although North America is certainly out). What’s more, genetic studies tell us that no living group of wolves is more closely related to dogs than any other, which means that the wolves that originally gave rise to dogs are now extinct. Sequencing living wolves and dogs will never truly reveal their shrouded past; it’d be, as Larson says, like trying to solve a crime when the culprit isn’t even on the list of suspects.<<
