Barry Arrington should stick to what he’s good at — banning blasphemers.
Instead, he has disinterred the corpse of the “natural selection is a tautology” argument, propped it up in a chair, and is now attempting to engage it in conversation.
Trust me, Barry – that corpse is dead, dead, dead. Among the coroner’s findings:
1. Even the dimmest of IDers and creationists accepts that “microevolution” occurs. Insects become pesticide-resistant. Finch beaks change in response to drought conditions. Microbes acquire antibiotic resistance. How does this happen? Through natural selection. It ain’t a tautology.
2. The tautology mongers miss a basic point about fitness. Fitness is <i>not</i> defined in terms of the reproductive success of an individual. An unfit individual who gets lucky and reproduces successfully does not get reclassified as fit. A fit individual who gets hit by a meteorite isn’t reclassified as unfit. To claim that “the fittest” are “those who survive”, as the tautology mongers claim, is ridiculous.
Back to hunting down blasphemers, Barry. Leave the science to those who understand it.
