...then he would have to conclude that zebras, for example, would be more "complex" (perhaps in some unspecified manner that Darwin could not foresee) in 2002 than they were in 1830.

This is a rather blatant misstatement of evolutionary theory. Evolutionary theory makes no predictions about the evolution of any species. Likewise your time scale is far too short. Such short times are not predicted by evolutionary theory.

Evolutionary theory makes no predictions about the evolution of any species.

I was specifically addressing a comment by that poster in which he described the progressive complexity of species as a basic tenet of Darwinism. Even if you could not measure the difference between a zebra in 1830 and a zebra in 2002, the zebra in 2002 must be more "complex" if this principle is true.
