References 71 and 72 were incorrect in the original bibliography. The correct citations should be:

[71] Dediu, D., Ladd, D.R. 2007. Linguistic tone is related to the population frequency of the adaptive haplogroups of two brain size genes, ASPM and Microcephalin. Proc. Natl. Acad. Sci. U. S. A. 104, 10944-10949.

[72] Wong PC, Chandrasekaran B, Zheng J (2012) The derived allele of ASPM is associated with lexical tone perception. PloS One 7: e342434.
