Who can resist the sweet pleading of puppy dog eyes? New research suggests that dogs actually evolved new muscles to allow them to give people soulful gazes in order to better communicate with us. A study published in June in the journal Proceedings of the National Academy of Sciences, compared the anatomy and behavior of dogs and wolves, and concluded that domesticated dogs developed a muscle that gave them the ability to raise the inner eyebrow. The researchers also believe that puppy dog eyes or “expressive eyebrows” in dogs seem to compel humans to want to take care of them.
