Darwinist evolutionary theory seems to account beautifully for selections made according to the external, environmental pressures, but is entirely silent about the internal, biologically- or organismically-driven ones.

Actually, Darwin had quite a bit to say about sexual selection. Descent of Man is mostly about sexual selection, not only in mammals generally, but also insects, birds, and man himself.

Good point.

Yeah, PH but -- good grief! Am I the only one around here to notice that, before sexual selection can be put on the table, there has to be a successfully surviving organism capable of having sex in the first place? This is precisely the part of the problem that Darwin seems to leave out of his theory.

Thousands of years, before Darwin, of breeders breeding via well-chosen sexual pairings for characteristics and yet the closest they ever came to a new species was the mule. And it can't reproduce.
