Today is the 200th anniversary of the birth of Charles Darwin! Let's celebrate together! But how?
Well, you could go to the Darwin Day website and see if there are any local events. Its search form seems to work terribly for me, though.
You could also read the complete works of Darwin online here, in his own handwriting! Darwin had messy handwriting though, so maybe you'd prefer just to read The Origin of Species online in a font of your choosing.
If you're already well-versed in evolutionary theory, you could go pick a fight with some creationist morons. If you choose to do so, the talk.origins archive should provide you will all the information you need to refute their bullshit.
You could also look at this nice graph showing public acceptance of evolution in various countries. Then you can celebrate that America isn't quite as stupid as Turkey!
Or you could just watch this very pretty video with Sir David Attenborough. I think I even spotted my friend the archaeopteryx in it!
If audio is more your style, you could also check out a bunch of Nature podcasts about Darwin & evolution. Despite using the terrible term "podcast," they're still pretty cool.
Whatever you do, enjoy!
ps It's also the 200th anniversary of the birth of Abraham Lincoln. So... ummm... read Hello Fitchburg or watch "Bill & Ted's Excellent Adventure" or something? Darwin's vastly more important in the grand scheme anyway.
