Laughter among primates

Lots of cool research has been published lately about primates and how complicated and awesome we are.

The latest is research showing that at least four primates other than humans use the same muscles, vocal intonations, and so on, to laugh at stuff that is funny, namely tickling.

I have more that I can share later, but for now: more adorable photos of primates from Woodland Park Zoo.

Rafe also had an awesome encounter with a snow leopard; definitely a complex interplay between mammals there. I’ll ask him to blog about it here.
