You're right, clearly it doesn't always work slowly--- Darwin's own
observations are enough to illustrate that. I guess I should've been more
specific. Evolution in some contexts works rapidly in terms of generating
positive survival adaptations, and usually works rapidly at eliminating
negative survival adaptations; it's just relatively slow at removing net-zero
adaptations.
