The shapes of bird beaks are highly controlled by nondietary factors
Open accessAbstract
Significance: We show that beak and skull shapes in birds of prey (“raptors”) are strongly coupled and largely controlled by size. This relationship means that, rather than being able to respond independently to natural selection, beak shapes are highly constrained to evolve in a particular way. The main aspects of shape variation seem to correspond with specific genes active during development. Because raptors are not each other’s closest relatives, similar shape constraints may therefore have been present in the ancestors of all modern songbirds, including Darwin’s finches, the classic example of explosive evolution in birds. If this hypothesis is true, then such classic examples may be unusual, needing first to break a genetic lock before their beaks could evolve new shapes.

“This contrasts with previous analyses that have found the avian cranium to be highly integrated. However, these previous analyses have been restricted to analyzing smaller clades (10, 12) or have excluded large portions of the skull (9).”

“Regardless of whether raptors occur at the base of two major radiations of monophyletic landbirds (25) or whether Accipitridae are found at the base of all landbirds, with Falconidae sister to the parrots and Passeriformes (26), it raises the question of whether integration and allometric control on form is basal to l…”

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.
