We now know that talking requires a big fancy brain, such as humans have and snakes conspicuously don’t (and don’t have room for)
Nitpick:
Talking the way we do maybe requires a big brain. We have no reason to think talking in general requires one. AFAIK, there’s no consensus on when language evolved, but many or most scientists seem to think it was after the human brain grew to its present size, not before.
New Caledonian crows have intelligence generally comparable to that of chimpanzees; not as great as, but not much less than either. Yet their brains weigh only 7-8 grams. Large snakes can have much larger brains than that. Anyway, brain size is relative to body weight; EQ is a better measure.
