Increased prefrontal cortex size in primates is associated with more complex social behaviors and decision-making.

“there's there's there's this sort of proliferation of different strategies that requires a lot more mental calculation apparently that um that goes hand inand with an increase in brain size cortex size uh which makes sense from the standpoint of like more prefrontal cortex more context dependent strategy setting and decision- making and it could be based on it seems that with more prefrontal cortex one can um a species can incorporate uh different valuations of mates it's it can be about hormonal status and I want to make sure we get back to that how humans signal hormonal status um but it could also be about uh you know reproductive potential as it relates to Resource allocation or um whether or not they'll be a good caretaker I mean a lot of additional factors can be incorporated um in and working with more variables flexibly requires more neural real estate mostly in prefrontal cortex right”
