Of course you wear’t, since you haveactually acknowledged my facial contortions as a “smile”, and smiles are excellent.

The 30 million years figure comes from scientists who discovered that both human and chimpanzee babies will program facial motions that looklike smiles when they are asleep. These facial expressions are understood as “spontaneous smiles” and are thoughtabout the evolutionary origin of genuine smiles and laughter. It may not be too unexpected that chimps smile, duetothefactthat we understand they are fairly close to us on the evolutionary tree. However, these scientists likewise discovered that these spontaneous smiles likewise exist in Japanese macaques, a much more far-off relative.
