>why do brains look like that
they have a lot of folds so that they have a bigger surface area
a bigger surface area means there's more grey matter which is what you use to think (niggers, ironically, have brains of pure white matter and lack grey matter)
apparently it also shortens the distances between neurons so less time is needed for thinking, and the shape is really what just happens because of the thick skull around it
