I agree MuddyWaters, when I came across this I was seriously floored - every time I think the WT can't say or do anything more stupid they never fail to disappoint.
I should also note that larger cranial capacity doesn't necessarily correlate to higher levels of intelligence. This is because neural density and plasticity - not brain size - are the most important factors. For example, Neanderthals had an average cranial capacity of 1600 cm(3) much larger than modern humans who only come in around 1400 cm(3).
