50 years of progress indeed. In addition, the biological sciences have almost completely traced a series of natural occurrences which lead from inanimate molecules to elementary living viruses. This statement reflects a certain naiveté about the complexity of living organisms. The Miller-Urey experiment may be what he's alluding to. But now their assumptions about the atmosphere have been disproven and there still hasn't been a major breakthrough in describing an evolutionary pathway from molecules to cells.
