Basic question: how can this be a sufficient explanation? There needs to be *some* advantage to having the bigger brain, it being “cheap” isn’t a good enough explanation...
OK I understand. JTBC, my original statement was: ” language and human culture created lead to a massive increase in returns to intelligence”, not that larger brains (/greater intelligence) suddenly became valuable.

My point is that the advantage to bigger brains existed long before humans.
This paper suggests that larger brains enable a more diverse diet.
