Disproving the Notion of Random Chance in Evolution is an Oxford University Press blog entry. The first paragraph:
Advocates of Intelligent Design contend that complex biological features cannot arise by chance, the implication being that chance equates to sentient forces. From a scientific vantage, however, the driving force of adaptive evolution–natural selection– is itself the antithesis of chance. Hereditary factors that promote organismal survival and reproduction in a particular environment tend to be precisely those that proliferate across the generations and thereby come to characterize natural populations. Whenever genetic variation and differential reproduction exist in nature (as they do in all known species), natural selection is inevitable, both logically and empirically. Biological traits that emerge from this inexorable operation may have the superficial aura of intelligent artistry, but that appearance is illusory (under a scientific interpretation). Natural selection can be a highly creative process (given a suitable supply of genetic variation to work from), but it is merely a mechanistic phenomenon– as inescapable and insentient as gravity.
