neocortex thus have an advantage, because that is where the sensory and motor regions are located.
-
Indeed, the ability to predict the behaviour of other individuals within a group seems to have conferred a large evolutionary advantage. Thus evolution would have favoured the growth of certain parts of the cortex that are responsible for social skills such as language, because they improved this ability.

cerebellum is a part of the brain involved in co-ordinating muscle movements

Many scientists believe that this growth in the primates’ neocortex reflects the growing complexity of their social lives

The model of the triune brain proposed by MacLean in 1970 is a useful piece of shorthand for the complex evolutionary history of the human brain.

Glen Scallion"The model of the triune brain proposed by MacLean in 1970 is a useful piece of shorthand for the complex evolutionary history of the human brain. But the brain's combination of reptilian, paleomammalian and neomammalian structures is far more intricate than a mere set of nested Russian dolls.
Ever since the first mammals appeared more than 200 million years ago, the cerebral cortex has assumed greater and greater importance compared with the brain's other, older structures. Because these structures had proven their effectiveness for meeting certain fundamental needs, there was no reason for them to disappear. Instead, evolution favoured a process of building expansions and additions, rather than rebuilding everything from the bottom up." -
