Dem smart Scientist types say, monkey's cant talk n that
explains thems lack of a grammar function in thems brains 
and why they don't talk much.

Research types in Japaneze discovered two whole different parts 
of the brain deal with grammar n vocabulary.

Kuniyoshi Sakai and colleagues at da Universinity of Tokyo found
dat monkeys only have da vocabulary function, but us humans gots
both.

Sakai said: "The grammar function allows southern people to 
verbally think, deduce, evaluate and decide, as well as 
speak and comprehend sentences."

"Monkeys may have some understanding of the words, but there is
no guarantee they understand these words in the same way
humans do or even southern people."

Hims say monkeys gots the ability to associate and memorise
symbols, and even understand words - but without a grammar
function thems guys can't piece em together.

Sakai and his team used dem MRI scanners to read dem brain response
in humans and monkeys to short memory tests and tasks
usin sentences and word lists.
