Related in Their Turn to the Primordial Bicycle

“To argue that the Ford Taurus evolved from the Model T because they each have four tires is a dubious procedure. Maybe four tires is just a good idea, and anybody who wants to build a car should use it. Maybe a pig liver does the same thing that a human liver does, and for similar reasons. A Chevy and a Ford both have tailpipes, and I am entirely in favor of this. There is no doubt a common reason for it, and we need not resort to the explanation that the two cars are cousins, sharing a common ancestor” (God Is, p. 16)
