I also found that Russian fox study to be fascinating. Especially when the scientists were breeding by selecting for friendly behavior and found characteristics of white patches and curly tails in the foxes. They said the white patches on the face and bellies along with the curly tails are characteristics found in domesticated animals. Even though they were genetically selecting for behavior alone that these other characteristics are somehow genetically linked.
Kembe had her yearly vet appointment on Monday and the vet said he had just watched a PBS special on dogs and he didn’t know that the Basenji was the oldest known dog breed directly descended from the wolf. He suggested I watch the show - which was very interesting. It’s called DOG TALES - NOVA Season 47, Episode 2, and its 54 minutes long. It first aired 2/12/20 and available to view until 3/11/20. You can watch it online or stream it. The Basenji is considered to be the “GRANDAD OF ANCIENT DOGS”, is the most ancient breed and the closet ancestor of the wolf. I really enjoyed the episode - it was very interesting.
