Race, Evolution, and Behavior: A Life History Perspective

“(An) incendiary thesis....that separate races of human beings evolved different
reproductive strategies to cope with different environments and that these
strategies led to physical differences in brain size and hence in intelligence.
Human beings who evolved in the warm but highly unpredictable environment
of Africa adopted a strategy of high reproduction, while human beings who
migrated to the hostile cold of Europe and northern Asia took to producing fewer
children but nurturing them more carefully.”
—Malcolm W. Browne, New York Times Book Review
“Rushton is a serious scholar who has assembled serious data. Consider just one
example: brain size. The empirical reality, verified by numerous modem studies,
including several based on magnetic resonance imaging, is that a significant and
substantial relationship does exist between brain size and measured intelligence
after body size is taken into account and that the races do have different
distributions of brain size.”
—Charles Murray, Afterword to The Bell Curve
“Describes hundreds of studies worldwide that show a consistent pattern of
human racial differences in such characteristics as intelligence, brain size, genital
size, strength of sex drive, reproductive potency, industriousness, sociability, and
rule following. On each of these variables, the groups are aligned in the order:
Orientals, Caucasians, Blacks.”
