"So why don't those hunting, flesh-eating chimpanzees have a larger
brain? Why don't true predators like lions and wolves have ultra-massive
brains?"

I do so wish you would stick to a point and not ask irrelevant
questions. There is an entireliterature concerning the interelated
factors of environment, anatomy, and behaviors and human evolution that
answers your question. A person first needs to know something about a
field of study more then a few slivers of info from here and there to
even ask relevant questions.

There is no way to slice and dice the evidence to make round peg fit the
square hole you desire. Use of meat as a dietary source is related to
human evolution, the rise of culturally bsed behaviors and human history
of population movement out of africa .
