Stephen J. Gould of Harvard:
“Organs of extreme perfection proclaim their value unambiguously; the difficulty lies in explaining how they developed…how can a series of reasonable intermediate forms be constructed? Of what value could the first tiny step toward an eye be to its possessor? The dung-mimicking insect is well protected, but can there be any edge in looking only five percent like a [bird dropping]? Darwin’s critics referred to this dilemma as the problem of assigning adaptive value to ‘incipient [incomplete] stages of useful structures….The argument still rages, and organs of extreme perfection rank high in the arsenal of modern creationists.”
