S25 E11: Dogs That Changed the World: Rise of the Dog

Aired: 10/21/2011 | 0:53:10 | Episode
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.
