Canine evolution

More research into canine evolution:

"a Collie has a skull shape that is more different from that of a Pekingese than the skull shape of the cat is from that of a walrus."

Essentially, human selection has created a higher diversity in skull morphology within canine than millions of years of natural selection created in the order Carnivora. Genes are amazing in their plasticity and in their perseverance.
