bigger the brain bigger the ultimate social unit




  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 '"
