I didn't realize that the 10th was Stephen Jay Gould's birthday. He would have been 70 years old. I wish I could have met him in person. He was one of the first popularizers of evolution that I read when I was growing up. He was my advisor's advisor - so I am, in a hierarchical academic sense, his grand-advisee.
Jerry Coyne has a wonderful discussion of Gould and his work. Go read it, you'll be glad you did.
