1) What is the strongest evidence that protobionts may have formed spontaneously? A) The fossil record found in the stromatolites. B) The discovery of ribozymes, showing that prebiotic RNA molecules may have been autocatalytic. C) The production of organic compounds within a laboratory apparatus simulating conditions on early Earth. D) The abiotic synthesis of polymers. E) The relative ease with which liposomes can be synthesized in laboratories. 2) Current theories of prebiotic evolution are based on evidence for all of the following except the abiotic A) production of small organic molecules. B) production of liposomes. C) replication of oligopeptides. D) origin of DNA-protein interactions. E) polymerization of amino acids. 3) The first genetic material was most likely a(n) A) DNA polymer. B) protein enzyme. C) DNA oligonucleotide. D) RNA polymer. E) protein. According to the Miller-Urey experimental results, chemical evolution leading up to and including the formation of living matter is believed to have occurred during the early history of Earth. Below are four pairs of events that might have occurred during this period. Judge the relative time of each of these pairs of events according
