Happy Birthday, Darwin!

Also, happy birthday to the other great emancipator, Abraham Lincoln, who was born the very same day as Darwin. Here's a nice quote from an article by Steven Conn that compares the two:

"Lincoln insisted on equality as a political fact. Darwin demonstrated it as a biological fact. In their shared commitment to human equality these two Great Emancipators, each in their own realm, helped us to break free from the shackles of the past."
