When the drought ended and the rains returned, however, food was plentiful, and the average beak size returned to normal.
Darwin gets credit by default for changes in organisms that should be seen instead as engineered products of foresight.
Taking the facts and arguments presented together, it appears to be clear that no macroevolution is happening in “Darwin’s finches.”
This is by no means an all-or-nothing selection (as the impression is sometimes given). Rather, the alleles are retained.
