COMMENT ON "Ongoing Adaptive Evolution of ASPM, a Brain Size Determinant in Homo sapiens"
Fuli Yu, R. Sean Hill, Stephen F. Schaffner, Pardis C. Sabeti, Eric T. Wang, Andre A. Mignault, Russell J. Ferland, Robert K. Moyzis, Christopher A. Walsh, David Reich
Abstract: Mekel-Bobrov et al. (Reports, 9 September 2005, p. 1720) suggested that ASPM, a gene associated with microcephaly, underwent natural selection within the last 500 to 14,100 years. Their analyses based on comparison with computer simulations indicated that ASPM had an unusual pattern of variation. However, when we compare ASPM empirically to a large number of other loci, its variation is not unusual and does not support selection.
