New Research Supports Meyer's Discussion of Pre-Biotic Chemistry in Signature in the Cell


A recent Nature publication reports a new technique for measuring the oxygen levels in Earth's atmosphere some 4.4 billion years ago. The authors found that by studying cerium oxidation states in zircon, a compound formed from volcanic magma, they could ascertain the oxidation levels in the early earth. Their findings suggest that the early Earth's oxygen levels were very close to current levels. This research supports Dr. Meyer's discussion in Signature in the Cell. On pgs. 224-226 of Ch. 10: Beyond the Reach of Chance, Meyer states that when Stanley Miller conducted his famous 1953 experiment simulating early Earth's atmosphere, he "assumed that the earth's atmosphere contained virtually no free oxygen." Meyer reveals that new geochemical evidence showed that the assumptions Miller had made about the early atmosphere were incorrect.

This new research is additional confirmation that oxygen was present in significant quantities. Because oxygen quenches organic reactions necessary to produce essential building blocks of life, the ability of inorganic materials to produce organic life, as chemical evolutionary theory assumes, is not possible.
