The gene Microcephalin (MCPH1) regulates brain size and has evolved unde
r strong positive selection in the human evolutionary lineage. We show t
hat one genetic variant of Microcephalin in modern humans, which arose 3
7,000 years ago, increased in frequency too rapidly to be compatible wit |

The gene ASPM (abnormal spindle-like microcephaly associated) is a speci
fic regulator of brain size, and its evolution in the lineage leading to
Homo sapiens was driven by strong positive selection. Here, we show tha
t one genetic variant of ASPM in humans arose merely about 5800 years ag
o and has since swept to hi |
