my point was their brain is not really a fraction of size when you compare it to their body mass, and anyway bigger brain doesn't really mean smarter animal necessarily, elephants are not that smart, so it's not really about size whether scaled or not
Why is the ratio important? Wouldn’t it be what the brain is capable of doing, determined by “wrinkles”? (Apparently the true indicator of intelligence, at least for humans). I’d imagine the bigger the brain in absolute terms, the more wrinkles, but who knows.
Most of the brain is not doing intelligence, it is doing nerves and muscle control. Larger bodies require larger brains because otherwise they wouldn't be able to control all the muscles needed to move.
