This week (and next), we talk about a couple of things that we humans do as social creatures. First we talk about laughter! We talk about the history of laughter, a weird case study about laughter, and Brittany makes Maria listen to a couple of audio clips of animals laughing. Let us know if you guys guess the animals correctly because Maria definitely didn’t. Watch the video recording here: https://youtu.be/BxnmG4ogFb4
