They try to sugarcoat this, but it still smacks of eugenics to me.
Lahn and his team observed that each of the gene classes were present among a significant number of the scanned subjects -- 30 percent in the case of the ASPM mutation, and 70 percent in the case of the microcephalin mutation.
The ASPM mutation was more prevalent in European-related populations such as Iberians, Basques, Russians, North Africans, Middle-Easterners, and South Asians, and less often found among sub-Saharan Africans, East Asians, and Native American Indians.
The microcephalin variant was also found with higher frequency outside of sub-Saharan Africa.
The researchers stressed, however, that no inferences could yet be drawn about the relative genetic evolution of one ethnic group over another, since many as yet unidentified genes probably play a significant role in brain development.
