Evolutionist criticisms of the RNA world conjecture
“Many of the theories on the origin of life may seem a little bizarre, but they come about when evolutionists realize the impossibility of chemical evolution producing life as we know it. One such evolutionist is Graham Cairns- Smith and his theory involving clay particles in the early earth. Cairns-Smith suggests that the many detailed experiments on the plausibility of chemical evolution have only gone to show the unlikelihood of its occurrence. It is highly unlikely that complex sugars and proteins (polysaccharides and polypeptides) could form, but even more unlikely that polynucleotides like DNA and RNA could spontaneously form. Cairns-Smith lists 19 difficulties that suggest the unlikelihood of the RNA world hypothesis and shows that the origin of life by a purely naturalistic accident is highly improbable.” Evolution Exposed, Second Ed., Evolutionist criticisms of the RNA world conjecture, Cairns-Smith.
