EARLY PROKARYOTIC LIFE ON EARTH. “Life was present on Earth by 3.6 or 3.5 b.y. ago but until the latest Proterozoic, 3 b.y. later, it was limited to single-celled organisms. Early on these were only of prokaryotes whose cells lacked nuclei—bacteria, including photosynthetic (which released O2) and methanogenic types and Archaea—but they later included probable unicellular eukaryotes with nuclei.”
