For those scientists who take it seriously, Darwinian evolution has functioned more as a philosophical belief system than as a testable scientific hypothesis. This quasi-religious function of the theory is, I think, what lies behind many of the extreme statements that you have doubtless encountered from some scientists opposing any critical analysis of neo-Darwinism in the classroom. It is also why many scientists make public statements about the theory that they would not defend privately to other scientists like me.

If Charles Darwin reappeared today, he might be surprised to learn that humans are descended from viruses as well as from apes.

Natural science in England, as Darwin already knew to his cost, was still the purview of Christian scholars. But here was a question that Darwin found compelling: if God had created all the creatures of the world, what possible reason could there be for the variations found in the Galápagos?

A century ago, people laughed at the notion that we were descended from monkeys. Today, the individuals most offended by that claim are the monkeys.

One of the truly bizarre things about our current cultural situation is that the leading figures of the scientific establishment seem genuinely amazed that the citizens do not accept finch-beak variation as proof of the claim that humans, like all animals and plants, are accidental products of a purposeless universe in which only material processes have operated from the beginning.

No fossil is buried with its birth certificate. That, and the scarcity of fossils, means that it is effectively impossible to link fossils into chains of cause and effect in any valid way... To take a line of fossils and claim that they represent a lineage is not a scientific hypothesis that can be tested, but an assertion that carries the same validity as a bedtime story—amusing, perhaps even instructive, but not scientific.

This new consensus seemed so compelling that Ernst Mayr, the dean of modern Darwinians, opened the ashcan of history for a deposit of Geoffrey's ideas about anatomical unity.

Adam is fading out. It is on account of Darwin and that crowd. I can see that he is not going to last much longer. There's a plenty of signs. He is getting belittled to a germ—a little bit of a speck that you can't see without a microscope powerful enough to raise a gnat to the size of a church.('The Refuge of the Derelicts' collected in Mark Twain and John Sutton Tuckey, The Devil's Race-Track: Mark Twain's Great Dark Writings (1980), 340-41. - 1980).

No Lord Almighty created the humans out of personal will. Creationism is simply a myth created by the weak and ignorant humans out of a psychological need to have a sense of eternal security.

I myself am convinced that the theory of evolution, especially to the extent to which it has been applied, will be one of the greatest jokes in the history books of the future. Posterity will marvel that so very flimsy and dubious an hypothesis could be accepted with the incredible credulity it has.
