The positive evidence for Darwinism is confined to small-scale evolutionary changes like insects developing insecticide resistance....Evidence like that for insecticide resistance confirms the Darwinian selection mechanism for small-scale changes, but hardly warrants the grand extrapolation that Darwinists want. It is a huge leap going from insects developing insecticide resistance via the Darwinian mechanism of natural selection and random variation to the very emergence of insects in the first place by that same mechanism.
