Sunday Is Darwin Day

Sunday is Darwin Day, the 203rd anniversary of the birth of Charles Darwin. On February 12 or near to it, all around the U.S. and indeed in many parts of the world, science organizations, museums, schools, and some churches too, will celebrate the man who taught us so much about the natural world and the workings of evolution.

The International Darwin Day Foundation notes a wider purpose to the day, as well: "More generally, Darwin Day expresses gratitude for the enormous benefits that scientific knowledge, acquired through human curiosity and ingenuity, has contributed to the advancement of humanity."

I'll mark the day by dipping into the complete works of Charles Darwin online, and by going outdoors (in the cold!) to observe the natural world in my backyard.
