However, mankind would initially have been largely unaffected by the
disease because our hunter-gatherer forebears ate meat and other
fat-rich foods.

Another very old skull was fished out of the Thames recently
http://www.canoe.ca/CNEWSScience0207/20_skull-ap.html.
This one like many another, showed evidence of a successful (the
individual survived) trepanning operation.
It is my impression that evidence of trepanning operations is so
prolific that it seems reasonable to suppose that it was a fairly
widespread practice.
It is widely held that this operation is to release bad spirits from an
afflicted person.
I suppose there is no way to tell if the bad spirits were in fact
schizophrenic, or whether these were ritual, as opposed to functional,
practices.
But in the light of the article it's hard not to wonder whether there is
not some connection.
Possibly we have evolved towards a lesser incidence of schizophrenia?
Thanks Walter.
Warm regards
