If I remember correctly, the process of evolution is not some unitary driving unintelligent force, but the product of at least three different phenomenon: (1) Natural selection (survival of the fittest): simply put -- in a competetive environment the species most well adapted to that environment survive, most likely at the expense of species less well adapted. The most obvious example of this is the human being. The species has not only adapted to its environment, but gone one step further and has begun adapting the environment to itself! For an example of species failing to compete, see any list of extinct or endangered species. (2) Random mutation: While this doesn't happen to complex critters in ways that are generally observable, it does happen to viruses and bacteria all the time. Some biologist correct me if I'm wrong, but I believe that Swine Flu virus that caused such a panic in the medical industry in 1976 was a mutated form of the swine flu virus responsible for the pandemic of 1918. There is a marvelous book called "Rats, Lice, and History" which describes developments in human history as a result of a genetic shift in the Typhus bacteria from Biblical times until today. The more complex the critter, the longer it takes to show up, but the evidence is there. (3) Genetic Drift: See the newspapers of two weeks ago for the Nobel Prize for observations of this exact phenomenon. Hybridization of plants -- a naturally occurring phenomenon -- has been observed and studied for centuries and is the basis for most of modern agriculture. Have I left anything out?
