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 slightest deviation from perfect genetic mixing and random reassortment could provide the required non-random distribution, hence there is no need for compartmentation and Wilson's model simplifies to any kin selection model fulfilling Hamilton's equation, which requires a larger-than-zero relatedness for an altruistic trait to increase its frequency.

    “The slightest deviation from perfect genetic mixing and random reassortment could provide the required non-random distribution (for example, relatives tending to stay together) hence there is no need for compartmentation (physical separation) and Wilson’s model simplifies to any kin selection model fulfilling Hamilton’s equation [92], which requires a larger-than-zero relatedness for an altruistic”
  • Close aggregation of compartments allows metabolic products to diffuse within protocell populations, and such products and whole complexes of functional polymers can be mixed throughout the aggregate and benefit the entire population, enabling a mechanism to support inclusive fitness.

    “Figure 8 (left) illustrates how the close aggregation of compartments allows metabolic products to diffuse within protocell populations. Such products, and whole complexes of functional polymers, can be mixed throughout the aggregate and thereby benefit the entire population, enabling a mechanism to support inclusive fitness (Hamilton, 1964).”

  • Parental reproductive fitness is inclusive of both their own surviving children and those of subsequent generations.

    “From an evolutionary perspective, parental reproductive fitness is 'inclusive' of both their own surviving children and those of subsequent generations (Hamilton, 1964).”
  • Evolutionary theories emphasize kinship and reciprocity in helping.

    “evolutionary theories emphasize kinship and reciprocity (42, 43)”

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.
