African-descended people (Blacks) average cranial capacities of 1267 cm3
, European-descended people (Whites) 1347 cm3
, and East Asian-descended people (East Asians) 1364 cm3
ethe race differences on IQ tests,
Blacks average an IQ of 85,
Whites 100, and
East Asians 106.
the race differences in brain size are correlated with 37 musculoskeletal
variables shown in standard evolutionary textbooks to change systematically
with increments in brain size. The 37 variables include cranial traits (such
as jaw size and shape, tooth size and shape, muscle attachment sites, and
orbital bone indentations), and postcranial traits (such as pelvic width,
thighbone curvature,
and knee joint surface area).
