Understanding Dog Domestication

The video explores the discovery of Dogor, an 18,000-year-old puppy found in Siberia, and its significance in understanding the domestication of dogs. It delves into the genetic divergence between dogs and wolves, the commensal pathway to domestication, and dietary adaptations linked to human agriculture. The video also discusses the debate on whether dogs were domesticated once or multiple times and presents archaeological evidence of the ancient human-dog bond. The video concludes with acknowledgments of contributors.
