From Grunt to grammar

Since the beginning of time, communication was one of the most important thing for human survival. But when and how did the first human learn to talk? To answer this question scientists study our ancestors body, more exactly their voice, also called Larynx box and their brain cavities. A very interesting fact about voice box is that the Adams apple found in the boys through is in fact the larynx  that is now that they are older, little bit down. As said in the article " There's some evidence that areas of the brain evolved in homo Habilis, the earliest human. So eve two and a half million years ago, our ancestors probably had at least the beginning of speech and language capabilities". What we also discovered is that early humans used, hands, facial expressions and language to communicate with others. We also Know that Early humans drew on cave walls, was it to communicate with others or just for pleasure, who knows?
