Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Saito et al. (2003) modeled solubility of Fe, Mn, Zn, Ni, Cu, Cd, and Co to evaluate plausible concentrations in ancient seawater under ferruginous, euxinic, and oxic conditions.

    “Saito et al. (2003) modeled the solubility of a suite of biologically essential trace elements (Fe, Mn, Zn, Ni, Cu, Cd, and Co) to evaluate plausible concentrations in ancient seawater under ferruginous (anoxic and Fe-rich), euxinic (anoxic and sulfide-rich), and oxic conditions (Fig. 1).”

  • Saito et al. emphasized that their projections of Precambrian seawater metal concentrations are based on thermodynamic models of mineral solubility and speciation in simulated seawater and are inherently limited.

  • Based on eukaryotic cellular requirements, geochemical modeling, and late emergence of eukaryotic Zn metalloenzymes, it was believed that Zn concentrations in early oceans would have been a possible barrier to eukaryotic evolution.

    “Similarly, based on eukaryotic cellular requirements, geochemical modeling, and the late emergence of eukaryotic Zn metalloenzymes, it was believed that Zn concentrations in the early oceans would have been a possible barrier to eukaryotic evolution (Williams and Frausto da Silva 2002;2003;Saito et al., 2003;Dupont et al., 2006;2010;Williams and Rickaby, 2012).”

  • The models of Saito et al. support the hypothesis that modern cyanobacterial trace element nutrient requirements may be viewed as the direct result of early evolution in ancient oceans limited in certain trace elements (Cu, Cd, Zn) and enriched in others (Fe, Mn, Co, Ni).

  • Predicted trace element concentrations in Archean oceans were in line with proposed cyanobacterial nutritional requirements but less so with eukaryotes, which evolved much later.

    “The predicted concentrations of trace elements available in the Archean oceans were in line with proposed cyanobacterial nutritional requirements but less so with the eukaryotes, which evolved much later.”

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.
