How Americans Celebrate Charles Darwin's Birthday

Happy Darwin Day! A time to play pin the tail on the sparrow, partake of “phylum feasts” (potluck dinners where the ingredients come from many different species), and generally give a thumbs-up to evolution’s godfather, Charles Darwin, on his 205th birthday, Wednesday.

A growing number of Americans of varied religious backgrounds are marking the 1809 birthday of the British naturalist whose masterpiece “On The Origin of Species” has never been out of print since its publication in 1859.
