An anthro student emailed me a reference cited by Rushton which shows
that neuron packing density and brain size correlate positively.

Has anybody explored the hypothesis that developmental stability is
responsible for brain size differences within populations? We recently
established a negative correlation between developmental stability and IQ
(measured as Cattell's culture fair test, which I believe tests spatial
and mental rotation abilities).
