Hence evolution as a whole has no preordained purpose or goal. Evolution is an ongoing, active process, not something that happened only in the dim, inaccessible past. In fact, it is observable as an ongoing process. Another familiar example is the common cold, which has so many forms that keep mutating that it is difficult to find a cure. Ditto for various bacteria that keep mutating, which explains how some strains can become resistant to antibiotics.
Evolution also operates in the normal functioning of organisms.
Ditto for vaccinations and allergy treatments. Despite the appearance of incredible sloth and waste, evolution turns out to be an amazingly creative process that, in some ways, is more efficient than any known method of rational design or planning. Thus evolution reverses older ideas about the economy of nature. Similarly, Darwinism reverses traditional explanations of apparently intelligent design. Roughly, evolution exchanges an infinite God operating at an instant for a dumb, massively parallel process acting recursively over a very long time.
