This is my one of my favorite YouTube videos. The song is catchy, and it’s SO freaking hilarious, especially if you’re familiar with arguments about evolution vs “intelligent design.” This came out, IIRC, around the time of the Scienceblogs kerfuffle about the film “Expelled,” and honestly, I don’t know if it’s meant to lampoon ID creationists or Richard Dawkins and other atheist scientists (including P.Z. Myers and Eugenie Scott who are “featured” in the video) – but it does a great job of poking fun at both sides. Best of all, hip hop Charles Darwin! As someone who identifies as a methodological materialist (but not a philosophical one), I adore this video. Geeky science humor doesn’t get any better than this.
