Happy 200th birthday, Charles Darwin.
In honor of Darwin’s profound scientific contributions, here’s a video featuring the BBC’s comfortingly educational nature show presenter David Attenborough. My favorite line in the video comes when Attenborough discusses the obvious evidence for evolution that surrounds us in the natural world: “You would have to be extrordinarily blinkered if you didn’t stub your toe against the theory of evolution very early on in your life.”
