“We know the abiotic world is very good at making amino acids. Abiotically produced amino acids are literally raining down on our heads, in meteors. It is difficult to imagine a primitive biological world of evolution, ultimately producing RNA and RNA precursors, that did not make use of amino acids, which were highly available from the get-go, and are so easy to combine to form wonder polymers. So the pure RNA World — I don’t accept it. There had to be many other molecules involved. And a dirty RNA World is a co-evolution world, with protein and RNA evolving together.” — Loren Williams
