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?

  • Domestic dogs exhibit more juvenile morphological traits (e.g. shortened muzzles and smaller canines) than wolves.

    “Previous studies have suggested that domestic dogs exhibit more juvenile morphological traits (e.g. shortened muzzles and smaller canines) and social behaviour (e.g. increased play and lower intensity of aggression) than wolves and that the variability of juvenile morphological traits among dog breeds covaries with their signalling behaviour [22–24].”
  • Selection against aggression may contribute to behavioural and phenotypic traits commonly expressed in humans, bonobos and dogs.

    “The self-domestication hypothesis argues that selection against aggression may contribute to behavioural and phenotypic traits commonly expressed in humans, bonobos and dogs [24].”
  • The variability of juvenile morphological traits among dog breeds covaries with their signalling behaviour.

    “Previous studies have suggested that domestic dogs exhibit more juvenile morphological traits (e.g. shortened muzzles and smaller canines) and social behaviour (e.g. increased play and lower intensity of aggression) than wolves and that the variability of juvenile morphological traits among dog breeds covaries with their signalling behaviour [22–24].”
  • Domestic dogs exhibit more juvenile social behaviour (e.g. increased play and lower intensity of aggression) than wolves.

    “Previous studies have suggested that domestic dogs exhibit more juvenile morphological traits (e.g. shortened muzzles and smaller canines) and social behaviour (e.g. increased play and lower intensity of aggression) than wolves and that the variability of juvenile morphological traits among dog breeds covaries with their signalling behaviour [22–24].”
  • The anatomically modern human profile is associated with an overall reduction of sexual dimorphism, which is also associated with domestication.

    “This profile is sometimes called ‘feminized’ [21], and is associated with an overall reduction of sexual dimorphism, which is also associated with domestication [25].”

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.
