“Adopting this view of the world means accepting not only the processes of evolution, but also the view that the living world is constantly evolving, and that evolutionary change occurs without any goals.’ The idea that evolution is not directed towards a final goal state has been more difficult for many people to accept than the process of evolution itself.”
(Life: The Science of Biology by William K. Purves, David Sadava, Gordon H. Orians, & H. Craig Keller, (6th ed., Sinauer; W.H. Freeman and Co., 2001), pg. 3.)
“The ‘blind’ watchmaker is natural selection. Natural selection is totally blind to the future. “Humans are fundamentally not exceptional because we came from the same evolutionary source as every other species. It is natural selection of selfish genes that has given us our bodies and brains “Natural selection is a bewilderingly simple idea. And yet what it explains is the whole of life, the diversity of life, the apparent design of life.”
(Richard Dawkins quoted in Biology by Neil A. Campbell, Jane B. Reese. & Lawrence G. Mitchell (5th ed., Addison Wesley Longman, 1999), pgs. 412-413.)
“Of course, no species has 'chosen’ a strategy. Rather, its ancestors ‘little by little, generation after generation’ merely wandered into a successful way of life through the action of random evolutionary forces. Once pointed in a certain direction, a line of evolution survives only if the cosmic dice continues to roll in its favor. “[J]ust by chance, a wonderful diversity of life has developed during the billions of years in which organisms have been evolving on earth.
(Biology by Burton S. Guttman (1st ed., McGraw Hill, 1999), pgs. 36-37.)
“It is difficult to avoid the speculation that Darwin, as has been the case with others, found the implications of his theory difficult to confront. “The real difficulty in accepting Darwins theory has always been that it seems to diminish our significance. Earlier, astronomy had made it clear that the earth is not the center of the solar universe, or even of our own solar system. Now the new biology asked us to accept the proposition that, like all other organisms, we too are the products of a random process that, as far as science can show, we are not created for any special purpose or as part of any universal design.”
(Invitation to Biology, by Helena Curtis & N. Sue Barnes(3rd ed., Worth, 1981), pgs. 474-475.)
