Creature Features by Steve Jenkins (2014)
Let's face it. Even as babies, we humans pay close attention to faces. Observing another person's features and expressions tells us whether they are happy, angry, excited, or sad. And when we look at an animal, it's hard not to imagine that its face is communicating human feelings. This isn't true, of course. Squinty eyes, an upturned mouth, or another odd expression is probably there because, in some way, it helps that animal survive.
