Like many evolutionists, Dawkins can twist any behavior or phenomenon to conform with Darwinian evolution.

While it is true that evolution can by 'reformulated to be far from tautological', and when so formulated is a proper scientific theory, the polemical defenders of neo-Darwinism, Dawkins at their head, go out of their way to render the theory unfalsifiable, and thus non-scientific.
