Abstract We test the hypothesis that polymorphisms of the brain regulator genes MCPH1
and ASPM contribute to variations in human brain size and its correlates. We measured
general mental ability, head circumference and social intelligence in 644 Canadian adults ...

... 2005), strong homology to genes not associated with the brain (Ponting 2006), and a lack of
correlation between ASPM haplotypes and normal human brain size variability (Rushton et al.
2006; Woods et al. 2006; Dobson-Stone et al. 2007; Thimpson et al. 2007). ...

... And Lahn's own work with other scientists has failed to correlate variants of the genes ASPM
and microcephalin with IQ ... In one study, Lahn helped controversial psychologist Philippe Rushton
of the University of Western Ontario in London, Canada, test whether people who carry ...
