Feathers Before Flight

Clarke, Julia·2013·Science

Abstract

Fossil data indicate that feathers and their precursors may have evolved over a much longer span than previously thought.

Statistics

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

Claims the paper makes

This paper’s full text isn’t openly available, 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 branched, pennaceous flight feathers of modern birds evolved from tubular integumentary appendages of early theropod dinosaurs such as Sinosauropteryx, and were subsequently co-opted for an aerodynamic function with the evolution of asymmetrical pennaceous feathers in Paraves.

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.
