Researchers from SUNY Polytechnic Institute found that seeing someone yawn makes people more vigilant to threats.

It’s thought that yawning evolved as a signal to the group that one of them is tired.

The tendency to be attuned to, and affected by, the yawns of others may have evolved due to the outcome this had on enhancing survival within groups.
