The speed of evolution in domestication

In PNAS today an article on "Evolution of facial muscle anatomy in dogs" which argues for an adaptation of canine facial anatomy in the context of domestication.

From the abstract: "Domestication shaped wolves into dogs and transformed both their behavior and their anatomy. Here we show that, in only 33,000 y, domestication transformed the facial muscle anatomy of dogs specifically for facial communication with humans."
