Abstract. High-degree melting of hot dry Hadean mantle at ocean ridges and plumes resulted in a crust about 30 km thick, overlain in places by extensive and thick mafic volcanic plateaus. Continental crust, by contrast, was relatively thin and mostly submarine. At constructive and destructive plate boundaries, and above the many mantle plumes, acidic hydrothermal springs at ∼400 • C contributed Fe and other transition elements as well as P and H 2 to the deep ocean made acidulous by dissolved CO 2 and minor HCl derived from volcanoes. Away from ocean ridges, submarine hydrothermal fluids were cool (≤100 • C), alkaline (pH ∼10), highly reduced and also H 2 -rich. Reaction of solvents in this fluid with those in ocean water was catalyzed in a hydrothermal mound, a natural self-restoring flow reactor and fractionation column developed above the alkaline spring. The mound consisted of brucite, Mg-rich clays, ephemeral carbonates, Fe-Ni sulfide and green rust. Acetate and glycine were the main products, some of which were eluted to the ocean. The rest, along with other organic byproducts were retained and concentrated within Fe-Ni sulfide compartments. These compartments, comprising the natural hydrothermal reactor, consisted partly of greigite (Fe 5 NiS 8 ). It was from reactions between organic modules confined within these inorganic compartments that the first prokaryotic organism evolved. These acetogenic precursors to the bacteria diversified and migrated down the mound and into the ocean floor to inaugurate the "deep biosphere". Once there they were protected from cataclysmic heating events caused by large meteoritic impacts. Geodynamic forces led to the eventual obduction of the deep biosphere into the photic zone where, initially protected by a thin veneer of sediment, the use of solar energy was mastered and photosynthesis emerged. The further evolution to oxygenic photosynthesis was effected as catalytic [Mn,Ca] -bearing molecules that otherwise wouldCorrespondence to: N. T.

Thus, a chemical sedimentary environment was required both for the emergence of chemosynthesis and of oxygenic photosynthesis, the two innovations that did most to change the nature of our planet.

Photosynthesis is the conversion of radiant energy, as light, into stored chemical energy. The central process is a light‐driven separation of electrical charge across a biological membrane. Photochemical reaction centres carry out this process, and their three‐dimensional protein structures now indicate that all modern reaction centres are homologous. Reaction centres with light‐harvesting complexes comprise photosynthetic units, two of which are required for the oxygenic photosynthesis that now dominates biological energy flow in the biosphere. The evolutionary origin of oxygenic photosynthesis in cyanobacteria had a profound effect on the chemistry of the Earth's atmosphere, on geology and on biology, paving the way for the evolution of complex, multicellular life. Eukaryotic plants and algae maintain the descendents of cyanobacteria as specialised, subcellular, cytoplasmic organelles called chloroplasts. The genes that remain in chloroplasts may be retained to be subject to regulatory control by the photosynthetic electron transport chain. Key Concepts: Photochemical reaction centres trap absorbed light energy as transmembrane charge separation. This vectorial electron transfer forms part of an electron transport chain, and drives vectorial proton translocation, establishing a proton motive force. The proton motive may also be produced by nonphotosynthetic electron transfer and perhaps, originally, by geothermal convection in the first living cells. Photosynthesis may have originated as a light‐driven supplement to vectorial metabolism. Photochemical reaction centres today come in two broad types, I and II. These differ in their mode of electron transport, but the three‐dimensional structure of their proteins indicates a common origin. Type I and type II reaction centres originated by gene duplication and subsequently diverged to give the reaction centres found today in different lineages of anoxygenic, photosynthetic bacteria, each with a single type of reaction centre. Type I and type II reaction centres came together again, in the first cyanobacterium, as photosystem I and photosystem II, two mutually interdependent photosynthetic units connected in series. Photosystem I and photosystem II together generate a sufficiently large electrical potential difference to permit photo‐oxidation of water and photo‐reduction of NADP + , with a consequent liberation of molecular oxygen. Oxygenic photosynthesis was acquired by eukaryotic cells through endosymbiosis with cyanobacteria. The overwhelming majority of cyanobacterial genes were either lost or relocated to the plant cell nucleus. Control of gene expression by photosynthetic electron transport may be an absolute and continuing requirement that justifies the maintenance of the small, quasi‐autonomous, chloroplast genetic system.

Photosynthesis originated once during the early Archaean due to the emergence of photochemical reaction centres, the biological nanomachines that convert the energy of light into chemical energy. The evolution of the photosynthetic machinery is consistent with a single origin of photosynthesis followed by an early diversification event that resulted in the rapid evolution of distinct reaction centre types and pigment forms. One of these reaction centres specialised in highly oxidising photochemistry, which facilitated the oxidation of Mn and the evolution of the water‐oxidising cluster of Photosystem II . In addition, the last common ancestor of all photosynthetic organisms can be traced back to a period of time near the root or at the root of the tree of life of bacteria, with the current distribution of photosynthesis being the result of widespread loss of photosynthetic capacity and horizontal gene transfer. Key Concepts Photosynthesis originated at least 3.5 billion years ago, but it could be much older. Photosynthesis evolved only once in ancestral forms of bacteria. Type I and Type II reaction centres originated from an ancestral gene duplication event. The last common ancestor of photosynthetic bacteria had type I and type II reaction centres. Photosystem II originated from the close interaction of a Type I and Type II reaction centre. The ancestral homodimeric Photosystem II was able to catalyse the oxidation of water. The last common ancestor of photosynthetic bacteria had protochlorophyllide and chlorophyllide reductase and could make pigments similar to chlorophyll a and bacteriochlorophyll g . Nitrogenase and the chlorophyll synthesis enzymes originated from an ancient gene duplication event predating the diversification of bacteria. The current distribution of photosynthesis in bacteria is explained by widespread loss of photosynthesis and horizontal gene transfer.
