I would put forth that most "racial" variations of behavior are more due to cultural influences than genetic.
LOL, what a coincidence! That's what the author claims in his book! You are a whiz.
Well, you would be wrong.
Twin studies show that genetics accounts for 97% of variability in fingerprints (duh!); 70% of IQ, 50% of sexual behavior, 50% of criminal activity and 40% of social attitudes.
Average IQ level of blacks is 15 points lower than whites. Average testosterone levels are 10-20% higher in college-age black males than whites. IQ and testosterone levels are key ingredients in behavior among young males.
Then which came first, the chicken (race) or the egg (culture)?
