Postpleistocene evolution of the brain?
Abstract
The number of extraneurons (Nc) has been calculated with the formulae of Jerison ('63) for prehistoric population samples to check the hypothesis that Nc may not only increase by increasing of cranial capacity but also by decreasing of body‐weight (gracilisation). Body weight of skeletal populations has been estimated by the formula of Debetz ('67). Samples from the Western part of Europe and Egypt support the hypothesis, but Eastern europoid samples display opposite relations: Nc increases with robusticity. It seems (as Jerison already suggested) that Nc is no measurement of the level of behavior in the populations of H. sapiens; but it may point towards allometric differences between West and East, which are also known for other characters.

“If the small-brained Middle and Late Pleistocene hominins H. naledi (blue dots) and H. floresiensis (orange dot) are included, these two change points merge into a single, overlapping encephalization event between 1.97 and 2.21 million years ago.”

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.
