It’s Darwin’s birthday (196 years–approaching the bicentennial!), and in honor of the day, a good gesture would be to attend one of the events scheduled as part of the Darwin Day Celebration. Or, failing that, it would be a good time to make a donation to the National Center for Science Education. Or your local public school–to the science program. Or even take a few minutes to read the late Ernst Mayr on Darwin’s Influence on Modern Thought.
