In the first quote above, are you familiar with the "testing" that he speaks of?
And in the second quote, would you have any intellectual sympathy with such a statement? Would you not be inclined to believe that organisms evolving in differing environs might evolve with differing characteristics?
I believe that if you took n individuals (where n consisted of a large enough sample to be statistically significant) of African origin, and n of any other race, and gave them equivalent upbringings - education, economic benefits, support, family life, etc. and then administered a standardized intelligence test to both groups, the results would be bell curves that were statistically indistinguishable from one another.
