the process that led to high interelligence, is probably related to nutrition.
as a mammal, growth after birth is not yet complete and the possibility of long fine food or to take mother's milk allows also growth of the brain.
with monkeys, it needs here a growing together of the cranial bones early, since the teeth must be used early.
i think superiority has become more and more prevalent here and intelligence has been the driving force for evolution.
