Nor can we be impressed with the reasons [Dawkins] has since accumulated in the name of science and offers to us now. Concerning the all-important question of the origin of life, he says,
“The major ingredient was heredity, either DNA or (more probably) something that copies like DNA but less accurately, perhaps the related molecule RNA. Once the vital ingredient—some kind of genetic molecule—is in place, true Darwinian natural selection can follow, and complex life emerges as the eventual consequence. But the spontaneous arising by chance of the first heredity molecule strikes many as improbable. Maybe it is—very, very improbable. . . . The origin of life is a flourishing, if speculative, subject for research. The expertise required for it is chemistry and it is not mine. [Emphasis added]”
