Happy Darwin Day!

Darwin's much-loved "Shut the fuck up while I'm explaining this tree-thing" face.  

In honor of Darwin Day, I've posted my favorite picture of Darwin and one of my favorite quotes.

  " Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science."  

-Charles Darwin
