Absolutely false. They are not even different species (as evolutionists continue to claim after it has been disproven). The beaks of the finches grow larger and smaller according to rainfall. They go back and forth in size within a few years. This is adaptation, not mutation and is therefore not evolution. This has been known since 1980 when it was published in a Pulitzer Prize Winning book but evolutionists continue to tell this lie.
More blue science in action. 3000 is mis-representing "The Beak of the Finch", which field report's primary point was that the finches varied because their diets had specialized, with the beaks matching against the various food source specializations. That the beaks varied in size with availability is no more relevant to this central point than the fact that humans average size increases with dietary improvement.
