In honor of Charles Darwin's birthday on February 12th, I am posting a series of diaries on Darwin and his theory. My first entry in this miniseries covered the basics of Darwin's theory of evolution. My second essay addressed some of the objections that have been made to Darwinian evolution and showed how year after year we find more evidence to support the theory of evolution. Today, I want to finish this miniseries by describing something about Darwin himself.

Since I will be busy herding a group of pre-teens to pizza, a movie and a party on the 12th, I will finish this series of essays one day early. Happy Birthday, Mr. Darwin. This one's for you!
