Studies of the finches of the Galapagos ring a knell to the complaints of the Creationists. These studies show that evolution is an ongoing process and that it occurs in our time. They explain why some species remain static over long periods of time while some rapidly diversify. They explain both the punctuation and the equilibria of punctuated equilibria, and speciation both with and without geographical separation. They illustrate the intimate and often reciprocal interaction between animals and their environment. They explain why the rate of evolution is often very slow when the fossil record is examined, but can be very rapid when the interaction of a species with extreme environmental changes is examined over short periods of time. They especially falsify the claim that there is not enough time for evolution to occur. [p165]
