The take-home lesson is that evolution, on its best day, is an embarrassingly anemic process.
The study was able to directly measure mutations after they occurred in the plant but before mutations could have been affected by natural selection.
It should be obvious: if you are controlling the mutations and selecting the outcomes, you are not doing Darwinism.
Cichlid variation do not primarily originate from random mutations but from engineered systems.
Professor Lenski’s contrasting of the frequency versus importance of evolutionary changes is misconceived and his illustrations are inapt.
