20[20] As Lovelock has argued with great persuasion, it is only because of bacterial activity on a planetary scale that conditions hospitable to life have been preserved for and beyond the 3 billion years in which only bacteria and archea (another group of single-celled organisms) were the only living organisms on the planet.
Deep-sea communities comprised by members of Archea had to resort to terrestrial instead of solar energy with reduced sulfur compounds becoming the major electron donors for aerobic microbial metabolism, thus evading the corrosive effects of the newly generated "pollutant.
Recent work has suggested that in at least some archea, the specific translation initiation mechanism depends on whether the gene in question is located internal to an operon or is an isolated gene or the first gene in an operon (Tolstrup et al.
