"These findings give reason to take up the hypothesis that the dramatic increase in brain volume over the course of human evolution has been the result of natural selection favoring general intelligence."https://www.sciencedirect.com/science/article/pii/S0160289618301703 …

There's evidence it was always mutual?
Not always. Sadly. But often enough for long term pair bonds to form.

I don't see why mutual mate selection would influence brain volume any more than one-sided (male) mate selection. Theories for your theory?

My book 'The mating mind' explains the reasoning. If one-sided selection favored brain size & intelligence, only one sex would evolve larger brain size & higher intelligence.
