In my mind, this turns out to be something of a semantic question. Obviously, Darwin wasn't opining about changes in nucleic acid sequences; he was looking at observable differences, and in that area I'm not so sure natural selection doesn't still reign supreme.

Dawkins's answer to the question echoes that sentiment. Nevertheless, the fact is that natural selection does not account for most evolutionary change. |
... at the molecular level.
This is the neutral theory of Motoo Kimura, indeed.
It is my opinion, but substitutions of billions of non-coding nucleotides don't represent any "evolutionary change". They don't have any impact on the phenotype.
