Hey Tim, Thanks for sharing this. Definitely very interesting. I would say that this provides evidence that something like this may have occurred as an early event in the process by which life originated. I think it is unlikely that this particular ribozyme was in existence at that time however. But the fact that this mechanism exists means that other molecules may also have utilized it. Keep in mind we never prove anything in science, we only generate evidence in support of a particular theory or hypothesis. Anyways that’s my two cents. I am a nutritional biologist and I teach organic chemistry and biochemistry at Sacramento State. Chad Cox Sent from my iPhone Chad L.
