A crew from BBC Earth left a camera out in the midst of a group of baboons. A pretty large camera, with a lens that acted as a mirror. Instead of wrecking the camera out of curiosity, the baboons wanted to examine their own reflections. What the camera recorded was a wide variety of reactions and facial expressions among the troop, not unlike what you'd expect from humans in front of a mirror. This clip is from the show The Secret Life Of Primates: Baboons. -via Laughing Squid
