For example, creationists often explain the development of resistance to antibiotic agents in bacteria, or the changes wrought in domesticated animals by artificial selection, by presuming that God decided to create organisms in fixed groups, called "kinds" or .
Though natural microevolution or human-guided artificial selection can bring about different varieties within the originally created "dog-kind," or "cow-kind," or "bacteria-kind" (!
Multiple copies are made of them, but the copies are not perfect; random changes are introduced during the copying process.
In a pool of randomly generated candidates, of course, most will not work at all, and these will be deleted.
However, purely by chance, a few may hold promise - they may show activity, even if only weak and imperfect activity, toward solving the problem.
reationists occasionally charge that evolution is useless as a scientific theory because it produces no practical benefits and has no relevance to daily life.
However, the evidence of biology alone shows that this claim is untrue.
