That’s what evolution is defined as—changes in gene frequency.
And how does this relate to the jibber-jabber that is Darwin’s _On_the_Origin_ofSpecies? I can’t find the word “gene” in the index.
I wouldn’t use the word “evolve” to describe the death of a species in a handful of generations. I wouldn’t use the word “evolve” to describe any process that begins and then terminates only over a handful of generations.
Instead, in this particular case, I would describe it as a failure mode of the species’ genetic mechanisms.
I think “evolving to extinction” is an unhelpful and misleading way to describe this particular possible failure mode of a species’ genetic mechanisms. (I don’t doubt the phenomena couldn’t or doesn’t exist.)

Undoubtedly because Darwin didn’t know what genes were. Genetic change over a period of several generations: sounds like evolution to me.
In addition, I believe you may have misread Eliezer’s comment: the gene may take a long time to reach the point where the species dies out. It’s only “one more generation” once the gene has evolved to fixation.
