A few years ago, a bunch of researchers sat next to 33 chimpanzees and started yawning a lot. Guess what the chimpanzees did? They yawned back! They helped prove what we’ve all known for a long time: yawning is contagious!
The researchers made a lot of chimps look pretty sleepy, but no word yet if there was an increase in nap time for both researchers and chimpanzees.

If we can make chimpanzees yawn, can animals make us yawn? Scroll through these pictures and let us know if feel a yawn coming on!








That’s really cool how you could catch a yawn from a chimpanzee!
