Let us recall that Bill refuses to believe that two species of crocodiles are related by common descent, or two species of sparrows, or two species of apes. How much more difficult would it be to convince him that a bacterium and an amoeba are related?

Fortunately “Convincing Bill” isn’t very high on science’s list of priorities.
