Fuzzy Face

Red Sox first baseman Mike Napoli shaved his beard, and it made the news. When you think about it, hair is a very strange thing. I mean, long, thin filaments erupting from tiny holes in our skin ~ and we do things with it. We cut it, grow it, extend it, shave it, color it, de-color it, gel it, braid it, cornrow it, lose it, try to get it back. And then there's the face ~ well, the male face. Now, that's weird. Evolutionarily, what does it all mean? Animals have hair all over; we don't. Why not, and what, if anything, does it have to do with trichromatism and emotions?: http://www.bbc.com/future/story/20140926-are-hairy-faces-less-evolved
