evolution: finding useful proteins (Introduction)

Folded proteins of large size are necessary because they have specific functions in the biochemistry of life and are absolutely vital for life to exist. they are why the Darwin theory does not work:

"An enormous literature documents the collapse of Charles Darwin’s theory in light of evidence (or lack of it), artfully summarized in Claremont Review of Books by the distinguished computer scientist David Gelernter. The Cambrian explosion of new species, Darwin’s critics observe, should have been preceded by pre-Cambrian forms, but those simply do not exist:

“'The trunk was supposed to branch into many different species, each species giving rise to many genera, and towards the top of the tree you would find so much diversity that you could distinguish separate phyla – the large divisions (sponges, mosses, mollusks, chordates, and so on) that comprise the kingdoms of animals, plants, and several others – take your pick. But, as [David] Berlinski points out, the fossil record shows the opposite: ‘representatives of separate phyla appearing first followed by lower-level diversification on those basic themes.’ In general, ‘most species enter the evolutionary order fully formed and then depart unchanged.’ The incremental development of new species is largely not there.”

"And that is not the worst of it. The new science of DNA proves mathematically that the odds of a random mutation leading to an improvement in the adaptability of a living organism are effectively zero, Gelernter shows. Even a small protein molecule has a chain of 150 amino acids. If we rearrange them at random we mostly obtain gibberish. In fact, “of all 150-link amino acid sequences, 1 in 1074 will be capable of folding into a stable protein. To say that your chances are 1 in 1074 is no different, in practice, from saying that they are zero. It’s not surprising that your chances of hitting a stable protein that performs some useful function, and might therefore play a part in evolution, are even smaller,” Gelernter explains. That is Establishment science, not the murmurings of the Creationist fringe. (my bold)

"In short, the evolutionary biologists can’t explain how animal life made the great leap from protozoans to arthropods in the Cambrian Explosion, let alone how natural selection through random mutation might have shaped the human mind. Biologists do brilliant and important research, to be sure, and the profession should not be blamed for the exaggerated claims made by a few publicists like Harari or Harvard’s Steven Pinker."

Comment: the bolded paragraph shows why Darwin's materialistic chance mutation type evolution cannot work. these special large molecules must be designed. See the next entry about how tiny proteins also play a role in the so-called 'junk' areas of DNA.
