Abstract

Oxygenic photosynthesis supplies organic carbon to the modern biosphere, but it is uncertain when this metabolism originated. It has previously been proposed 1,2 that photosynthetic reaction centres capable of splitting water arose by about 3 billion years ago on the basis of the inferred presence of manganese oxides in Archaean sedimentary rocks. However, this assumes that manganese oxides can be produced only in the presence of molecular oxygen 3, reactive oxygen species 4,5 or by high-potential photosynthetic reaction centres 6,7. Here we show that communities of anoxygenic photosynthetic microorganisms biomineralize manganese oxides in the absence of molecular oxygen and high-potential photosynthetic reaction centres. Microbial oxidation of Mn(II) under strictly anaerobic conditions during the Archaean eon would have produced geochemical signals identical to those used to date the evolution of oxygenic photosynthesis before the Great Oxidation Event 1,2. This light-dependent process may also produce manganese oxides in the photic zones of modern anoxic water bodies and sediments.

  • The interpretation of sediment manganese enrichments is robust regardless of the possibility of oxygen-free manganese oxidation through UV photooxidation, photosynthetic oxidation, or oxidation with elemental sulfur, given rapid manganese reduction under anoxic conditions.

    “This interpretation of sediment manganese enrichments is robust regardless of the possibility of oxygen-free manganese oxidation-through UV photooxidation (Anbar & Holland 1992), photosynthetic oxidation ( Johnson et al. 2013), or oxidation with elemental sulfur (Daye et al. 2019)-given rapid manganese reduction under anoxic conditions (e.g., Busigny et al. 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
