There is also a chapter on Darwin's finches in "Icons of Evolution."
In that chapter, Jonathan Wells complained that the finches are not an example of natural selection in action because no new species arose under the watch of Peter and Rosemary Grant in their famous study on the Galapagos Islands.
Wells actually argued against the significance of the observed evolutionary changes that allowed the finches to adapt to their changing environment because the changes did not produce any new species during that time.
Interestingly, these changes were arguably less dramatic than the icefish example that FtK accepts as merely "microevolution."
