Maybe, we just don't know! One hypothesis for example claims the exact opposite, that we started living with more people so we could "outsource" some efforts to others.

it's hard for me to imagine tribes & clans dramatically gaining size ~100Kyrs ago to the extent that it would make such a dramatic, species-wide difference in brain size.

I would tend to guess the reasons were multifactorial, at least. Possibly environmental changes and interbreeding (there were five other humans back then IIRC) were factors.
