Evolution of Dogs And How They Communicate With Humans

Over the years of dogs being domesticated, dogs evolved in ways to better communicate with their human companions. Dogs evolved something that wolves do not have, they evolved small muscles around their eyes that allow them to raise their inner eyebrow to communicate.
My reaction to this article is that I never realized how evolved dogs were, or how intelligent they were. They use only a small muscle to communicate with humans, who they depend upon for survival.
