Neanderthals had a bigger braincase than Homo Sapiens. It’s not likely that they were any smarter than us, but we can’t totally rule that out. They’re so closely related to us that their genes for bigger heads ought to be pretty compatible if we splice them in where they belong. Would literally bigger brain volume with otherwise Sapiens neurons make us any smarter?
