Abstract

The biogeochemical sulfur cycle plays a central role in fueling microbial metabolisms, regulating the Earth’s redox state, and affecting climate. However, geochemical reconstructions of the ancient sulfur cycle are confounded by ambiguous isotopic signals. We use phylogenetic reconciliation to ascertain the timing of ancient sulfur cycling gene events across the tree of life. Our results suggest that metabolisms using sulfide oxidation emerged in the Archean, but those involving thiosulfate emerged only after the Great Oxidation Event. Our data reveal that observed geochemical signatures resulted not from the expansion of a single type of organism but were instead associated with genomic innovation across the biosphere. Moreover, our results provide the first indication of organic sulfur cycling from the Mid-Proterozoic onwards, with implications for climate regulation and atmospheric biosignatures. Overall, our results provide insights into how the biological sulfur cycle evolved in tandem with the redox state of the early Earth.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The age of LUCA is sensitive to the root calibration used.

    “This is consistent with previous work suggesting that the age of LUCA is sensitive to the root calibration used19,21,27,95,96.”

    From ATP synthase evolution on a cross-braced dated tree of life (2023) · cites this paper as [95]

    In Results (Construction of species tree and time-calibrated chronogram), LUCA age estimates differ substantially between the liberal and conservative calibration sets, and Table 1 shows that the LUCA root prior differs between those sets. However, the paper also changed several other calibration points at the same time, so it does not establish sensitivity to the root calibration alone. (LLM, conf=0.82)

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.
