"Without [natural selection], we reason, there would be nothing but incoherent disorder. I shall argue... that this idea is wrong. For, as we shall see, the emerging sciences of complexity begin to suggest that the order is not all accidental, that vast veins of spontaneous order lie at hand. Laws of complexity spontaneously generate much of the order of the natural world. It is only then that selection comes into play, further molding and refining. Such veins... have not been entirely unknown, yet they are just beginning to emerge as powerful new clues to the origins and evolution of life." [Stuart Kauffman, At Home In The Universe]

After 30 years of research, Kauffman shows that given a certain threshold level of molecular diversity, the emergence of a very primitive life form, or protolife (life being very difficult to define exactly), is practically inevitable.
