evolution of emotions through perception of motion?

Virginia Hughes has a nice article on a study (Sievers, Polansky, Casey, and Wheatley 2012) suggesting “that our ancestors first learned to interpret emotion from movement“. There was a particular question of any universal application of the results, so the team also ran the experiment in a completely different culture. Very nice. The writing itself is worth the read, but Hughs also manages to clearly summarize the experiments and what’s at stake.
