Pat was feeling Darwinian, so Ben treats him to a crash course on the philosophy of evolution. While Pat diverts Ben's train of thought like branches on the Tree of Life, Ben attempts to explain how Charles Darwin's theory of evolution by natural selection upended our view of our role in the universe, showing that the tremendous complexity of all life on this planet is the result of blind luck amid generations of mindless death. Darwin ruined everything and Pat is pissed. More like Evil-ution, amiright guys?
