The earliest blade industries in North Africa are called Iberomaurusian (located mainly in the Oran region). This industry appears to have spread throughout the coastal regions of the Maghreb between 15,000 and 10,000 BC. Neolithic civilization (animal domestication and agriculture) developed in the Saharan and Mediterranean Maghreb perhaps as early as 11,000 BC or as late as between 6000 and 2000 BC. This life, richly depicted in the Tassili n'Ajjer paintings, predominated in Algeria until the classical period. The mixture of peoples of North Africa coalesced eventually into a distinct native population that came to be called Berbers, who are the indigenous peoples of northern Africa.
