How does this compare to modern Western brains? Data from scholar J.P. [b]Rushton shows that Caucasian enlisted men in the U.S. army have a mean cranial capacity of 1468 (Standard Deviation (SD) = 91) and for Caucasian women the mean and SD are 1284 and 90 respectively. From here it can be deduced that a sex-combined sample (that was 50% men, 50% women) would have a mean and SD of 1376 and 137 respectively.[/b] > > Can't we have fair play in te4h quotes given? I'm disappointed.
