Proteins 1

Living matter is composed largely of proteins, which are long chains of amino acids. Since 1930, it has been known that amino acids cannot link together if oxygen is present. That is, proteins could not have evolved from chance chemical reactions if the atmosphere contained oxygen. However, the chemistry of the earth’s rocks, both on land and below ancient seas, shows the earth had oxygen before the earliest fossils formed (a). Even earlier, solar radiation would have broken water vapor into oxygen and hydrogen. Some hydrogen, the lightest of all chemical elements, would then have escaped into outer space, leaving behind excess oxygen (b).

a. An authoritative study concluded that the early biosphere contained oxygen before the earliest fossils (bacteria) formed. Iron oxides were found that “imply a source of oxygen enough to convert into insoluble ferric material the ferrous solutions that must have first formed the flat, continuous horizontal layers that can in some sites be traced over hundreds of kilometers.” Philip Morrison, “Earth’s Earliest Biosphere,” Scientific American, Vol.*250, April 1984, pp.*30–31.

“In general, we find no evidence in the sedimentary distributions of carbon, sulfur, uranium, or iron, that an oxygen-free atmosphere has existed at any time during the span of geological history recorded in well-preserved sedimentary rocks.” Erich Dimroth and Michael M.
