Here again I think we have a problem with popularizations. I don't think there is any question that Dawkins would like to tie the origin of life with Darwinism. The intents of one of the Yockey posts that I submitted to the reflector was to uncouple Darwin from the prebiotic soup paradigm. Yockey argues that one should not determine Darwin's position on this matter from private correspondence but rather from what he published for public scrutiny. Yockey then gives some quotations from OoS indicating that Darwin's views were very much like those of Niels Bohr, i.e. that life is inscrutable.
Life just is.
I believe Darwin also used gravity as an analogy.
