"Compare Asian vs black bums and the child IQ and i think you will notice a patern that doesn't support the title."
Compare apples to apples. So, compare two women of the same economic and racial and age profile, who sport a large v. skinny behind.
I am sure if this study did not take this into account. Then, we could infer that black women have smarter kids than asian. Then again, "asian" is broad term with wide a range of ethnicity. I would be offended to be painted with such a wide brush. In fact, Africa, has the widest human genetic diversity of any continent. This means you can't determine ethnicity, based of skin color or geographic location. In other words, whites and asians and mid eastern people, all have a common father 30k years ago. While two black people could diverge genetically 150K years ago, simply due to tribal isolation.
