Dogs That Changed the World: The Rise of the Dog

Passport Season 25 Episode 11 | 53m 10s Video has closed captioning.

This film explores how the domestication of dogs might have taken place, including the theory of biologist Raymond Coppinger that it was the animals themselves — and human trash — that inspired the transformation. The genetic analysis of Peter Savolainen of the Royal Institute of Technology in Sweden has placed the origins of domesticated dogs — and those of the first dog — in East Asia.
