Lincoln and Darwin

A number of writers have been drawing comparisons between Abraham Lincoln and Charles Darwin since both were born 200 years ago today. Here is my favorite so far, taken from the comments section of the Mere Comments weblog (scroll down to the 3rd comment after the article):

Two men whose lives had great impact on the lives of millions, even billions, were born 200 years ago today. The one preserved the Union while defending the principle that all men are created equal. The other destroyed faith while giving a basis for the principle that men were not created at all. The one left us with a legacy worth dying for. The other left us a philosophy which gives us nothing worth living for.
