Formation of a new race takes place when, over several generations, individuals in one group reproduce more frequently among themselves than they do with individuals in other groups.

On average, the Chinese, Koreans, and Japanese are more similar to each other and are different from Australians, Israelis and the Swedes, who in turn are similar to each other and are different from Nigerians, Kenyans, and Jamaicans.

We emigrated to South Africa and later to Canada so I went to school in several places.

I then moved to the University of Western Ontario where I was made a full professor in 1985.

Race differences show up early in life.

Of course, individuals vary greatly within each racial group and should be treated as such.

Blacks in the Caribbean, Britain, Canada and sub-Saharan Africa as well as in the United States have low IQ scores relative to whites.
