we got the best
brain body ratio of all mammals
why'd that develop ?
attention Rouseau :
all the better to unit
with lots of OTHERS of our kind ...
=====================================
Robin Dunbar, of Liverpool University in England:
" the size of a primate's brain,
adjusted for the size of its body,
is directly related to the size
of the group it lives in "
( as with other social mammals,
like wolves )
--------------------------------------
"primeval homo sapiens
lived in ultimate groups of about 150"
"a clan "
" paleo hunter-gathers
meet only from time to time
mostly family bands foraged separately
but when they bumped into others of their kind
they know who's 'in the clan
and who ain't '"
