Proto-Berber language reached the stage where these different branches of this language family evolved. From that perspective, Proto-Berber was the first Berber stage to depart from Proto-Afrosiatic in the eighth millennium. It was restructured several times during the almost 10,000 years that separated it from its modern shape, which has preserved few relics. Roger Blench (2018) suggests that Proto-Berber speakers experienced intense language leveling about 2,000 years ago as the Roman Empire was expanding in North Africa. Hence, although Berber had split off from Afroasiatic several thousand years ago, Proto-Berber itself can only be reconstructed to a period as late as 200

In the third millennium BC, proto-Berber speakers spread across the area from Morocco to Egypt. In the last millennium BC, another Berber expansion created the Berber peoples noted in Roman records. The final spread occurred in the first millennium BC, when the Tuareg, now possessing camels, moved into the central Sahara; in the past, the northern parts of the Sahara were much more inhabitable than they are now.
