    This whole entire argument is completely illogical. We have studied brain development and genetics for years yet have never come up with a single shred of evidence of genetic factors that point to this conclusion. Not to mention that it would be easy to see if it actually existed. One can come up with an evolutionary hoopla story to back ones thesis but if you actually look at the general logic behind this study one can clearly see that this cannot be taken seriously as factual science. With so many possible causes due to development, nutrition, IQ test specifics, education, social factors and test groups  anyone who actually chooses to think while reading this can plainly see that there are far too many variables to simply state that genetics is accountable. Differences in health and the formation of the body is completely different than stating that a specific group of people have a vastly different functional capability of an organ.

      There is NOTHING BUT conclusive evidence that blacks lag behind in pretty much everything. Whites who grow up poor with poor nutrition still score higher than blacks. In the 1930s there was less crime but more poverty. You're just making excuses for these 'people'.

      Every single Country in Africa is 3rd world. We colonized it in the 1400s. We reduced Japan to nothing but rubble in WW2 and now they are a superpower.

      Stop being in denial of something so blatantly obvious, especially to what everyone knows. There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so.

      Equality is a myth, and I'd rather have a DOG around my children than a WOLF.
