When the human genome project was just completed, I heard one of the scientists involved in the project speaking on national television. He said that the decoding of human DNA showed that there was NO such thing as RACE. There is no genetic differences between people of different races other than skin color and hair and eye color. It is merely a case of dark skin, dark eyes, and dark hair being a dominate trait and being naturally selected for in certain populations where there was no intermarriage with light skinned, light eyed people (which are recessive traits.) It is the equivalent of saying that tall people (which is another dominant trait) are one race and short people are another and all the variants in between are "mixed race". Or, people with large noses are one race and people with small noses are another race.
This belief is based upon ignorance and the superficiality of the human ego developed over millenium combined with our desires to be superior to one another. It is a delusional denial of our true natures. What happens if enough people of so-called different races breed over hundreds of years, which is a real possibility with modern global travel. "Race" would eventually disappear and become meaningless when all our children are "mixed" to sufficient degree that their superficial differences become indistinguishable.
There are many factors that have been proven to affect intelligence, proven with scientific and medical studies. Some of them are poverty, malnutrition, illness, and lack of early educational opportunities. These are all conditions that are over-represented in the black populations in America as well as on the continent of Africa. These are the true reasons that blacks have traditionally performed less well on IQ tests (tests that have been show to be flawed due to bias in favour of certain cultures and educational systems). While these factors that can affect intelligence exist to a greater degree in SOME black populations this is certainly not a genetic indicator of a lesser intellectual potential.
