It's also Charles Darwin's birthday.
Lincoln wasn't perfect-- he was actually a racist, and for most of his presidency, believed that everyone would be better off if Black Americans were moved to Haiti and Panama after the war. However, he was still a man who's resolve never faded, and knew that the struggles he faced were part of something bigger than himself. He was called everything from appeaser to tyrant by his detractors, and yet without him, we might be be living in two
very different countries today, instead of one nation under God, indivisible, with liberty and justice for all.
Darwin helped bring credibility to the theory of evolution, by applying his theories about natural selection to it (he didn't author the theory of evolution itself, however). It certainly changed the landscape of the scientific community for the next 150 years, but I don't think that's quite comparable to making choices that ultimately may have drawn the map lines of the world as we know it. The finches on the Galapagos islands weren't going anywhere, so it'd only be a matter of time before someone else came to the same idea as Darwin. The civil war, on the other hand-- one bad call, and it would have been bye-bye to the sweet ol' US of A, and hello to the American Confederacy and the American Union.
So, with due respect to any Darwin fans out there, I would like to present the following concept for everyone's consideration:
Lincoln's birthday > Darwin's birthday
