At PhysOrg a new article review puts the kabash on the RNA-world hypothesis.
“I’m convinced that the RNA world (hypothesis) is not correct,” Caetano-Anollés said. “That world of nucleic acids could not have existed if not tethered to proteins.”
“This is a very engaging and provocative article by one of the most innovative and productive researchers in the field of protein evolution,” said University of California at San Diego research professor Russell Doolittle, who was not involved in the study. Doolittle remains puzzled, however, by “the notion that some early proteins were made before the evolution of the ribosome as a protein-manufacturing system.” He wondered how – if proteins were more ancient than the ribosomal machinery that today produces most of them –”the amino acid sequences of those early proteins were ‘remembered’ and incorporated into the new system.”
We, too, remain “puzzled” as to how all of this came about via undirected processes.
Here’s the paper.
Another day; another bad day for Darwinism. (So much to explain, and so little to explain it with!!)
