REPORT: “For example, as the proportion of the African component increases, the temporal surfaces move posteriorly and inward. The proportion of the European component is associated with protrusion of the occipital and frontal surfaces. Increases in the proportion of the East Asian component are accompanied by variations in temporal-parietal regions. The Native American component is associated with flattening of the frontal and occipital surfaces.”
“I would have expected the authors to show the total brain volumes for each group, but I cannot find those in the paper, nor in the supplemental materials. A pity, because it would help resolve some debates about brain sizes.”
