Yes it CAN...genetics is what makes whites and Asians "better". We are hybrids, Neanderthal and "human", blacks are NOT hybrids. They never got that boost that we did...it's WHY they're ALWAYS at the bottom of the barrel. There are NO "black paradises". There aren't even black places a normal person would want to live.

Genetically, they're a different species. They're like the "first original corn" the native americans first found compared to modern genetically ENHANCED modern corn. One has 5-6 kernels (low IQ) the other is LOADED with kernels (high IQ). Get it? Genetically they are 50,000 years behind.
