the early egyptians were caucasoid. from 3400 to 1800 B.C., egypt excelled in architecture, mathematics, and science. as egyptians moved south, up the nile river, they encountered black africans, who were brought back as slaves. miscegenation spread, egyptians became blacker, and egyptian civilization began a decline from which it has never recovered. ''the weak, disease-ridden population of modern egypt offers dramatic evidence of the evil effects of a hybridization which has gone on for 5000 years.'' (garrett, 1960, p. 7). today, egypt is a third world country with an average IQ of only 77 to 83.
