Abstract
It is suggested that evidence for the onset of an oxygenic atmosphere and the appearance of O (sub 2) -producing photosynthesis can be derived by examining the distribution of delta (super 13) C values from rocks of a given period. Prior to the appearance of free O (sub 2) in large, stable quantities, microbial diversity could have been great and this might be reflected in a wider variability of delta (super 13) C in C (sub org) in sediments from the pre-oxygenic Earth. Available isotope data offer support for this hypothesis; microbial variability appears to have diminished markedly by approx 1500 m.y. and to have remained relatively low thereafter.
