Case Studies that Clarify Evolution and Its Power Dr. King begins by explaining key mechanisms through which evolution functions, citing famous and definitive case studies that demonstrate these forces. In one such landmark study, for example, biologists Peter and Rosemary Grant returned to the Galapagos Islands more than 100 years after Darwin's first voyage to conduct research on island finches. In 1977, a drought-induced scarcity of soft, edible seeds brought forth in the very next generation a population of finches with larger, stronger beaks capable of crushing larger, tougher seeds.(This is an example of adaptation. If I moved to the Himalayas and lived at a higher elevation than I had before, would I have trouble breathing? Yes, but my offspring wouldn't because they were born into the higher elevations.) Extraordinarily, in 1985, heavy rains produced a surplus of softer seeds, and natural selection produced a succeeding generation of the smaller-beaked variety.(So the birds lost genetic information? I don't understand how this is proof of anything but a bird becoming another bird. The bible says they will bring forth after their kind.) Evolution had occurred in two different directions within a decade. This "natural selection" is the theoretical tool of evolution, which helps us make sense of these facts.(If it's a theoretical tool, how is it a fact again? This sentence is called a tautology, or a sentence that means nothing.)
