LOL, here is the entire paragraph quoted from the article that you're posting some kind of paraphrase from:
"The microcephalin gene relates to brain size during development. A variant of this, haplogroup D, may have been positively selected for in modern humans – and may also have come from an interbreeding event with an archaic population (Evans et al. 2006). Mutations in microcephalin cause the brain to be 3 to 4 times smaller in size. All of the haplogroup D variants come from a single copy that appeared in modern humans around 37,000 years ago. However, haplogroup D itself came from a lineage that had diverged from the lineage that led to modern humans around 1.1 million years ago. Although there was speculation that the Neanderthals were the source of the microcephalin haplogroup D (Evans et al. 2006), the Neanderthal DNA recently sequenced does not contain the microcephalin haplogroup D (Green et al. 2010)."
Admit it, you were basically talking out your ass with the added bonus of getting in a "Africans (i.e. black people) are genetically inferior" dig.
Here's that entire Smithsonian article though, it's kinda interesting if ya like evolutionary biology, and germane to the OP:
