From Gray Wolf to Yorkshire Terrier. How?

I read this super interesting article in the February 2012 National Geographic Magazine. It’s all about dog’s DNA and like it or not our best friend artificially evolved to become the most diverse animal on Earth. Pretty interesting how the gray wolf became a cute Yorkshire terrier.

Breeders mix and match to get the best dog that would suit their needs. Mixing dogs to obtain desired attributes is a practise used since ancient Egypt. Dog’s sizes, colour, hair and so on is decided by changing a group of genes. Dogs are so different because of the unusual evolution that breeders created by pressing the forward button in the natural evolution of this specie.
