>>12712929Not op but while it would be "simpler" it would bypass the bigger and more useful ramification derived from the information above. Which is that specific neurological architecture can affect IQ without even touching brain size. Something that pretty much flies in the face of most IQ/Eugenics spergs who focus mainly on size and weight of the brain.
Which in retrospect actually makes sense as despite females having smaller brains than males their IQ averages don't heavily deviate. Also it could explain how even though Neanderthals had bigger brains modern humans still managed to beat them out intellectually. Maybe Neanderthals had bigger brains but with more frequent high density/dispersion while humans had smaller brains but with less density/dispersion (basically more organized architecture).
