Abstract : In the light of biochemical evolution, hemoproteids - resp. the porphyrin compounds they are based upon - must have existed on earth as early as biological organisms with oxydative metabolism occurred. Since the primitive early atmosphere was followed by a CO2-containing atmosphere that induced - at least partially - by photosynthesis the oxydating atmosphere, the porphyrin-compounds-synthesis(chlorophyll) must primarily have been combined with the CO2-assimilation, which means that the porphyrin catalyse of oxydative metabolism consequently derived from the second period of the early atmosphere. This aspect is discussed. (Author)
