New scientific evidence suggests that some wolves evolved into dogs by domesticating themselves, and not by humans taming them. This program features stunning evidence that dogs have travelled, and been buried, with humans since prehistory-adapting to every climate and evolving into many subspecies or types of the same dog species (Canis lupus familiaris). Human cultures might not have evolved as they did without the help of the dog, our most cherished, and probably first, domestic animal companion.
