A “self-cleaving ribozyme,” Pistol has to redeem itself without shooting the RNA World in the foot.
Now it seems that limits to evolution have become an argument for evolution.
Ribozyme experiments suggest that for life to originate, what was needed was a goal in mind, an agent in charge, with the means to implement a preconceived plan. We have a name for that.
Writing at ENV last month, I explained why proponents of intelligent design are justified in using the term “molecular machines.”
Researchers at the University of Illinois used phylogenetic modeling methods to evaluate the evolutionary history of the ribosome.
