Over the next week or so, I’m going to post a couple two-part posts. I’ve gotten mildly obsessed with two big topics in evolution: eyes and language. There’s been so much fascinating work done on both subjects in the past year or so that a single post just won’t do for either of them. I know that the blog genre lends itself well to quick hits, but I’m going to stretch things a bit. We’ll see how it works.
