PBS Digital Studios brings us a video that speculates on the evolutionary value of music and why the emotions it evokes are so universal.
New evolutionary science says that we may read emotion in music because it relates to how we sense emotion in people's movements. We'll take a trip from Austin to Dartmouth to Cambodia to hear why music makes us feel so many feels. The connections between movement and music go far beyond dance moves!
I would guess that language fits in there somewhere, because we can discern emotions in language even when we don't understand the words. You can find links to the referenced research at the YouTube page. -via Boing Boing
