Facial expressions project our internal emotions to the outside world. Reading other people’s faces comes naturally and automatically to most of us. Without your best friend saying a word, you know—by seeing the little wrinkles around her eyes, her rounded, raised cheeks and upturned lip corners—that she got that promotion she wanted.
We will get into some case studies in the end but before that here are some pictures of different animals smiling and laughing which we hope will make your day!!

The last but not the least
The study calls this system the Equine FACS (Facial Action Coding System), consisting of 17 action units, or discrete muscle movements. Each unique facial movement is used in a different social situation, and many of them appear similar to human action units, despite our vastly different facial musculature.
The finding reflects the complicated social organizations within groups of horses. Like humans and other primates, horses maintain complex relationships via communication. Since they are extremely visual animals, they rely on small but significant changes in facial expression to match a certain social or emotional context.
For example, horses widen their eyes to show more white when they are afraid, just as we do. Another comparable facial action is the Inner Brow Raiser, where horses raise the skin above the inner corners of their eyes in negative situations—notice what happens to your eyebrows when you pout.
Scientists have discovered that dogs produce more facial movements when a human is paying attention to them – including raising their eyebrows, making their eyes appear bigger – than when they are being ignored or presented with a tasty morsel.
The overlap between the systems used by different animals, and the synergy between dogs and humans in particular, suggests that, long ago in our evolutionary history, facial expressions were adaptive in some way. These studies add to the evidence that social factors and the need for communication played a key role in the evolution of facial expressions, for all of the species that use them.
