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?

  • The cnidarian-bilaterian LCA possessed a mouth, gut and multifunctional cells.

  • The cnidarian-bilaterian LCA (approx.720 Ma) was able to form primary and orthogonal body axes and regional organization of structures in relation to body axes.

  • By approximately 650 Ma, the bilaterian LCA was more highly tuned for direct interaction with environment and exhibited both anterior/posterior and dorsal/ventral regional patterning and elaboration.

  • The sponge-cnidarian LCA, the cnidarian-bilaterian LCA and the bilaterian LCA generally lacked the complicated morphogenetic developmental pathways observed in modern bilaterians, assuming sponges are basal to metazoans.

    “the sponge-cnidarian LCA (demosponge-cnidarian LCA if sponges are paraphyletic), the cnidarian-bilaterian LCA and the bilaterian LCA generally lacked the complicated morphogenetic developmental pathways observed in modern bilaterians.”

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.
