Race Is More Than Skin Deep
Is race real Do the races differ in behavior as well as in body Are such views just the result of white racism Modern science shows a three-way pattern of race differences in both physical traits and behavior. On average, Orientals are slower to mature, less fertile, less sexually active, less aggressive, and have larger brains and higher IQ scores. Blacks are at the other pole. Whites fall in the middle, but closer to Orientals than to Blacks. White men can't jump. Asian men can't either. But...

Black Mixed-Race White Asian Biological Black-White Biological Biological Parents Biological Parents Parents Parents Source Third Unabridged Edition of Race, Evolution, and Behavior pp. 187-194 Regression to the Average provides still another way to test if race differences are genetic. The children of very tall parents are taller than average. But they are shorter than their parents and nearer the average of their race. Similarly, children of very short parents are shorter than average, but...
Intelligence and Brain Size
IQ tests measure intelligence and predict real life success. The races differ in brain size and on IQ tests. On average Orientals have the largest brains and highest IQs. Blacks average the lowest, and Whites fall in between. The brain size differences explain the IQ differences both within groups and between groups. Psychologists use IQ tests to measure what we call intelligence or mental ability. Brighter people score higher on IQ tests than most people. Less bright people score lower. IQ...
Out of Africa
The latest theory of human origins -- Out-of-Africa -- provides the final piece to the puzzle. It explains why r-K theory accounts for race differences in body, brain, and behavior. As races moved out of Africa they evolved away from r-type behaviors and toward K-type. Moving out of Africa meant increasing brain size and IQ, but lowering reproduction, aggression and sexual activity. Based on his theory of evolution, Charles Darwin thought Africa was the cradle of mankind. He did not have any...
Maturation Crime and Parenting
Race differences start in the womb. Blacks are born earlier and grow quicker than Whites and Orientals. The three-way race pattern occurs in milestones such as sexual maturity, family stability, crime rates, and population growth. Black babies mature more quickly than White babies, while Oriental babies mature more slowly. African babies in a sitting position are more able to keep their heads up and backs straight from the start. White babies often need six to eight weeks to do these things see...
Genes Environment or Both
A number of studies show that race differences are caused by both genes and environment. Heritabilities, cross-race adoptions, genetic weights, and regression-to-the-average all tell the same story. Cross-race adoptions give some of the best proof that the genes cause race differences in IQ. Growing up in a middle-class White home does not lower the average IQ for Orientals nor raise it for Blacks. Can any environmental factor explain all the data on speed of dental development, age of sexual...
Sex Hormones and AIDS
Race differences exist in sexual behavior. The races differ in how often they like to have sexual intercourse. This affects rates of sexually transmitted diseases. On all the counts, Orientals are the least sexually active, Blacks the most, and Whites are in between. The races also differ in the number of twins and multiple births, in hormone levels, in sexual attitudes, and even in their sexual anatomy. The races differ in their level of sex hormones. Hormone levels are highest in Blacks and...
Life History Theory
The theory of r-K life histories explains the worldwide three-way pattern in race differences. The r-strategy means being very sexually active and having many offspring. The K-strategy means having fewer offspring, but with both mother and father giving them more care. Humans are the most K strategists of all species. Among humans, Orientals follow the most K-strategy, Blacks the most r-strategy, and Whites fall in between. The previous chapters showed that there are important race differences...
