Arab-Berber Arabization process in the Maghreb. Various population genetics studies along with historians such as Gabriel Camps and Charles-André Julien lend support to the idea that the bulk of the gene pool of modern Maghrebis, irrespective of linguistic group, is derived from the Berber populations of the pre-Islamic period. Arab-Berber Arab-Berbers (; ) are an ethnic group native to Maghreb, a North African region along the Mediterranean Sea and the Atlantic Ocean. Arab-Berbers are people of mixed Berber and Arab origin and whose native language is a variant of Maghrebi Arabic. Many Arab-Berbers identify primarily as Arab and secondarily as Berber.
Proto-Berber language are the only Berber languages to preserve Proto-Berber *β as β; elsewhere in Berber it becomes "h" or disappears. The Proto-Berber consonantal system reconstructed by Allati (cf. Allati, 2002, 2011) is based on remains from the ancient stages of this language preserved in the ancient toponymical stratas, in Libyan inscriptions and in the modern Berber varieties. It had stops b, t, d, k, g; fricative s; nasal n and liquids l, r. The stops of the phonological system have evolved since the proto-Berber stage into variants from which other consonants have been progressively formed (Allati, 2002, 2011). Karl G. Prasse
