Everybody yawns ... people, fish, snakes, and even marmots, as evidenced in this marvelous photo by Tony LePrieur. Yet while it appears that this member of the squirrel family with mouth agape is signalling its boredom, the reason we all yawn is still up for debate. One theory that has gained a lot of ground is that yawning helps regulate brain temperature. If that's the case, this seemingly non-impressed marmot must have a pretty cool brain.
