Facts do not 'speak for themselves'; they are read in the light of theory.

I can envision observations and experiments that would disprove any evolutionary theory I know.

Natural selection is just three factors - over-production, variation, and inheritance combined to produce adaptation to changing local environments. It's not a principle or progress; it's just a principle of local adaptation. You don't make better creatures in any cosmic sense; you make creatures that are better suited to the changing climates of their local habitats.

My own field of paleontology has strongly challenged the Darwinian premise that life's major transformations can be explained by adding up, through the immensity of geological time, the successive tiny changes produced generation after generation by natural selection.

I dreamed of becoming a scientist, in general, and a paleontologist, in particular, ever since the Tyrannosaurus skeleton awed and scared me.

We pass through this world but once.

Heydrich, Eichmann, and company therefore invoke the usual trick of argument for breaking a true continuum that lacks a compelling point for separation: choose an arbitrary dividing line and then treat it as a self-evident law of nature.
