In my quest to decode the primordial IQ cheat sheet, the biases that, among 
other things, make us mammals and human, I concluded that both hunting in 
groups and safety in groups provide tremendous incentives to work with small 
numbers. In wolves this could be implemented through anxiety signals, ie a wolf 
is not happy until she counts three or four around. In a tool-using animal I 
can see small multiplications arising, for example three different tools each 
for the 4 family members. ( the question I am trying to answer is how much 
arithmetic should be build in, and how much discovered, of course there are 
more anthropological ways to go about it, but I doubt any would be more valid 
given our lack of good definitions, among other things).
