They reason backwards: Birds evolved, therefore some poorly understood mindless processes must have driven them to evolve.
Of course finches don’t multiply and cycle through generations as rapidly as bacteria. Still, these birds have been isolated on the iconic islands for some 2 million years.
Many Americans reject evolution, a recent paper suggests, because they’re uninformed.
Finches on another island “would leave even Charles Darwin scratching his head.” But do they “help solve an evolutionary puzzle”?
Against the backdrop of research of Princeton’s Peter and Rosemary Grant, Darwin’s finches are among the most hyped illustrations of evolution in action.
