Offspring Quality and the Polygyny Threshold: "The Sexy Son Hypothesis"

Weatherhead, Patrick J., Robertson, Raleigh J.·1979·The American Naturalist

Abstract

An expansion of the Orians-Verner model for the evolution of polygyny has been made to explain evidence contradictory to that model. By separating the individual quality of the male from the quality of his territory and assuming that male offspring will at least in part inherit the individual qualities of their father, it was postulated that females mating with "attractive" males and suffering reduced reproductive success could ultimately gain an advantage through the success of their "sexy sons."

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.
