I can flip a coin any amount of times you want and can guarantee with an extremely high degree of accuracy which side it lands on. It's a simple parlor trick. In fact, I can, flip a quarter in my hand, and without looking at pretty much guarantee that whatever side you call, the other side will show up.
not saying god is a parlor trickster when it comes to "evolution", but let us say that the finches of note in the article, all "adapted" rather than evolved, because after all this time, they are still finches....
now as far as darwin's evolution, his theory has proved the galapagos were an excellent laboratory for adaption of species, but not a cross species evolutionary model.
this evolution from adaptation takes a great leap of "faith", pun intended.
