Biochemical identification of ammo-acids and monosaccharides in carbonaceous materials from the Witwatersrand indicates that there was life in Pre-Cambrian times. Electron micrographs of surface replicas of the surrounding rocks also suggest a probable organic derivation of these carbon concentrations.
