my car goes fast, my car goes slow, my car is sometimes parked. How in heck
can you define a car?
btw as Gould uses the term "fast" he means in geological terms. "Fast"
evolution can take thousands of years--a moment in geological history. The
duration of our own species is but a moment in geological terms. Evolution
is always very slow and gradual compared to the pitifully brief span of a
human life.
