I suppose one trouble with Darwinism is that, as Jacques
Monod perceptively remarked, everybody thinks he understands it. It
is, indeed, a remarkably simple theory; childishly so, one would have
thought, in comparison with almost all of physics and mathematics. In
essence, it amounts simply to the idea that non-random reproduction,
where there is hereditary variation, has consequences that are
far-reaching if there is time for them to be cumulative.
