Natural selection is almost always handled in general temps . . This means that it has no explanatory power when specific problems arise.

Darwinism has failed in practice. The whole aim and purpose of Darwinism is to show how modern forms descended from ancient forms, that is, to construct reliable phylogenies [evolutionary family trees]. In this it has utterly failed.

The two sides of the equation are the same. We have a tautology. The definition is meaningless.

The simplest case, where one is informed that a cat is black because it is black, may be harmless, though irritating and useless but the actual cases [in statements of evolutionary theory] are always harder to detect than this, and may darken counsel for a long time.

After observing mutations in fruit flies for many years, Professes Goldschmidt fell into despair. The changes, he lamented, were so hopelessly micro [insignificant] that if a thousand mutations were combined in one specimen, there would still be no new species.
