Fireworks. Photo by Creativity+ Timothy K Hamilton.It's Independence Day in the U.S. To celebrate, let me suggest the latest edition of the Carnival of Evolution, which is hosted this month by 13-year-old evolution blogger William. (He's dedicated the Carnival to some other patriotic holiday, but we'll overlook that.) The monthly roundup of online writing about evolution and all its scientific, cultural, and historical ramifications includes posts by John Wilkins, Zen Faulkes, and Byte Size Biology among many others. Go check it out while you're waiting for the barbecue coals to heat up.
