How Dogs (Eventually) Became Our Best Friends

The video explores the discovery of an 18,000-year-old puppy named Dogor in Siberia, highlighting its significance in understanding the domestication of dogs. It discusses the timeline of domestication, genetic divergence between wolves and dogs, and the commensal pathway that led to domestication. The video also examines the debate on whether domestication occurred once or multiple times and presents archaeological evidence of early human-dog relationships. Finally, it covers the development of modern dog breeds and the ongoing research into the origins of domestication.
