Chad has repeatedly betrayed: his non-comprehension of what a
species -
level change is (i.e. the focus of PE) and that this most minor of changes does not require a wholesale reordering of a genome; his inability to grasp that gradualism, although the clear minority
in the fossil record, is present
in various lineages (See Gould's various references to Foraminfera); his non-comprehension of the role of historic genetic contingency (i.e. that silent mutations can coalesce into rather dramatic novel functionality, e.g. Lenskis» E. coli); that the nodes of PE are more than sufficient for the requisite
species -
level evolutionary changes (See Pod Mrcaru lizards); etc, etc..

Man is
in reality, many persons now tell us, a biological

We debate endlessly about Peace, Democracy, the Rights of Man, the conditions of racial and individual eugenics, the value and morality of scientific research pushed to the uttermost limit, and the true nature of the Kingdom of God; but here again, how can we fail to see that each of these inescapable questions has two aspects, and therefore two answers, according to whether we regard the human
