So I've been doing some research on this controversial subject and I've come across some interesting information, I believe some of you guys maybe interested in.
According to research by J. P. Rushton - In a book titled: "Race, Evolution, and Behavior" he catogrized three biological races (or subspecies) of man - Orientals (i.e., Mongoloids or Asians), Blacks (i.e., Negroids or Africans), and Whites (i.e., Caucasoids or Europeans).
He stated:So Asians are smarter then Africans the Africans are at the lower end and the White (Europeans) are in between the both.There are recognizable profiles for the three major racial groups on brain size, intelligence, personality and temperament, sexual behavior, and rates of fertility, maturation and longevity. On average, Orientals and their descendants around the world fall at one end of the continuum, Blacks and their descendants around the world fall at the other end of the continuum, Europeans regularly fall in between. This worldwide pattern implies evolutionary and genetic, rather than purely social, political, economic, or cultural causes.
Actually guys I don't have time... Am attending a wedding soon...
Anyway you can read it here:
You need PDF viewer.
Furthermore, here is a good article you can read which just summaries it:
Race differences in average IQ are largely genetic (Sahara my not like this)
Although, I do suggest you read the book.
