The Achilles heel of Darwinism is brought out in this selection from WHEE. We simply don’t know how evolution works, because we don’t obsreve it properly.
In general, I think biologists might take a lession from history, and look at WHEE, to get the point that, e.g. the Axial Age, shows forms of evolution taking place so fast they are done in less than three centuries. Looking at deep time, and spouting natural selection as the answer is NOT science.
But the fallacy is almost impossible to correct.
