No! I'm asking you how you would measure or compare intelligence between peoples. You seem to have missed my point, if our brains are larger than Erectus' I asked you if that meant that each separate function had grown equally, and if not we cannot say that Erectus was less intelligent till we can measure it. Basic science.
An example, that part of the brain that controls involuntary actions, heart and respiration, would that be larger in our brain than Erectus?
Brocca's Bump, is ours larger than Erectus'?
Surely, beyond a certain size, any further increase would seem pointless would it not?
Any help will be apprecited.
I didn't find the right solution from the Internet.
