Also;

1. Genetic changes have sped up over the past 10,000 years (note that groups left Africa about 50,000 years ago).

2. Seven percent or more of all our genes are mutant versions that replaced earlier variants through natural selection over the last tens of thousands of years. There was little gene flow between continental clusters (“races”) during that period, so there is circumstantial evidence for group differences beyond the already established ones (superficial appearance, disease resistance).

3. A fair fraction are neurological and likely to affect behavior in some way. For example, you see new versions of SLC6A4, a serotonin transporter, in Europeans and Asians. There’s a new version of a gene (DBA1) that shapes the development of the layers of the cerebral cortex in east Asia.

4. Populations that adopted agriculture experienced Metabolic/diet changes like lactose tolerance, many changes in genes involved with defense against infectious disease, many changes in genes that affect hearing and smell, changes in neurotransmitters and related genes that most likely influence personality, changes in genes involved with the regulation of nerve connections and brain growth.

5. Populations vary in color-blindness, in the fraction of working olfactory genes, in visual acuity, in susceptibility to myopia. They vary in brain size by more than a standard deviation (from smallest to largest). And of course psychometric scores vary by more than that.

In 1997, 19.4 percent of all adult African immigrants in the United States held a graduate degree, compared to 8.1 percent of adult whites and 3.8 percent of adult blacks in the United States, respectively (The Journal of Blacks in Higher Education, No. 26 (Winter, 1999-2000), pp. 60-61). This information suggests that America has an equally large achievement gap between whites and African immigrants as there is between white and black Americans.

In the UK, 1988, the Commission for Racial Equality conducted an investigation on the admissions practices of St. George’s, and other medical colleges, who set aside a certain number of places for minority students. This informal quota system reflected the percentage of minorities in the general population. However, minority students with Chinese, Indian, or black African heritage had higher academic qualifications for university admission than did whites (Blacks in Britain from the West Indies had far lower academic credentials than did whites). In fact, blacks with African origins over the age of 30 had the highest educational qualifications of any ethnic group in the British Isles. Thus, the evidence pointed to the fact that minority quotas for University admissions were actually working against students from these ethnic groups who were on average more qualified for higher education than their white peers (Cross, 1994; Also see, C, Dustmann, N, Theodoropoulos, 2006).

According to the report The State of Working Britain, published by the Centre for Economic Performance at the highly regarded London School of Economics, 21 % of adult blacks in Britain with African origins have a university degree. Only 14 percent of adult white Britons are college educated. It has also been shown that black immigrants from Africa earn more money than do native born white Britons (C, Dustmann, N, Theodoropoulos, 2006):

And can we please pry the sycophant groupies out from around Nobel Prize winners, celebrities, politicians, and surgeons? I know it must feel good to have people laughing at every stupid joke they tell, day after day, but the fawning adulation obviously turns their brains to mush.
