Different instincts. Don't smile at a wild animal.
Reply:most animals do not have speech as humans do and that would be their way of telling you to get the heck away from them
Reply:Humans are animals. . dude. Humans also bare their teeth. Think about it. When you get mad, you grit your teeth, even though you might not open you lips, you still are doing that.


Animals do that because they can't use words. When animals are happy, they can't smile like humans.
Reply:asmile is a variation of the "fear face". baring your teeth while displaying submissive body language is an attempt to look non threatening. eventually that non threatening gesture was combined with the eye narrowing gesture meaning relaxed(as observed in dogs) to become a smile
Reply:Agree with the above posted. Smile is derived from other animals baring their teeth as a form of fear or aggression. In our species, the smile is used to display submission, friendly attitude and body language, so assume a non hostile stance, once out of fear, but now our of courtesy.
Reply:Animals bare their teeth because they are getting ready to kill and eat their predator. r
Reply:The bareing of teeth is not a universal sign of attack in the animal kingdom. Primates, such as chimps, bare their teeth to warn of danger. The same is true with dolphins, they show their teeth when they are excited, not to demonstrated that they are angry. People do it because along our evolutionary development it became an emotional marker to show how we were feeling.
