Maternal-Fetal Weight Relationships in Primates
Abstract
Analysis of maternal-fetal weight relationships in primates based on the regression equation F (fetal weight) = b · M (maternal weight)a indicates that prosimian and anthropoid primates are separated by an allometric shift which can be interpreted as a result of differences in placental structures. The regular occurrence of multiple births in both prosimians and anthropoids is limited to small-sized species only, and is considered to be the result of selective pressure against oversized dimensions of the fetus at term to guarantee successful delivery. Twinning in callithricids is demonstrated as having developed secondarily as a byproduct of evolutionary miniaturization, rather than as a retention of a primitive mammalian feature.

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.
