The Origins of Prebiological
Systems and of Their Molecular Matrices.
38) Most derive their views by considering only one or two types of evidence: sophisticated calculations of the amino acid sequences of truly ancient proteins, the repertoire of amino acids found in meteorites; simulations of an early, prebiological
planet Earth; and so on.
One of the problems with early biology on the early Earth is you need abundant nitrogen for all these prebiological
processes to happen - and of course nitrogen is in ammonia.
Many mysteries of this prebiological
history of the universe have been progressively unlocked by rational inquiry, especially mathematical inquiry into the universe's patterns and structures.
In the generalisation of the use of the algorithm (selection among equally probable variants) discovered by Darwin and soon to become, in its application to prebiological
and cosmological evolution, "omnivorous" (according to the definition of Dennett himself, 1995), lies the reason for the evolution of Darwinism itself from a scientific model to a fully fledged philosophy of chance and necessity.
Clays are surprisingly complex and may have played a cooperative role with catalytic peptides in an intermediate stage of prebiological chemistry preceding the emergence of life on earth (Rao et al 1980).
Oro 1980 Clays in Prebiological Chemistry, Journal of Molecular Evolution 15, 317-31.
Their work, which appears in the April 2 EMBO JOURNAL, supports the hypothesis of a prebiological
"RNA world," in which RNA molecules assembled and copied themselves, acting almost as independent living things.
Instead, he conflates the problems of generating information via biological and prebiological
natural selection, and in so doing, fails to grapple with the critical difficulties in origin-of-life research that partly underscore the cogency of my argument.
One of these, uracil, tends to react with formaldehyde, a molecule that scientists think existed abundantly on prebiological
In the prebiological
world, as a few molecules became predominant, they would have influenced other molecules with which they interacted.
In subsequent years, an interdisciplinary field of theoretical and experimental biochemistry, known as origin-of-life research, has itself evolved, driven primarily by biochemists eager to understand the fundamental, chemical mechanisms of prebiological
