A brief on Moroccan History

The Capsian culture brought Morocco into the Neolithic about 8000 BC, at a time when the Maghreb was less arid than it is today. The Berber language probably was formed at roughly the same time as agriculture (see Berber), and was developed by the existing population and adopted the immigrants who arrived later. Modern DNA analysis (see link) has confirmed that various populations have contributed to the present-day gene pool of Morocco in addition to the main ethnic group which is the Amazighs/Berbers. Those other various populations are Arabs, Iberians, Phoenicians, Sephardic Jews and sub-Saharan Africans.

Berber appearance

Berbers are the indigenous peoples of North Africa west of the Nile Valley. They are discontinuously distributed from the Atlantic to the Siwa oasis, in Egypt, and from the Mediterranean to the Niger River. Historically they spoke various Berber languages, which together form a branch of the Afro-Asiatic language family. Today many of them speak Arabic. Between 14 and 25 million Berber-speakers live within this region, most densely in Algeria and Morocco and becoming generally scarcer eastward through the rest of the Maghreb and beyond.
Many Berbers call themselves some variant of the word Imazighen (singular Amazigh), meaning "free people".[4][5] This is common in Morocco, but elsewhere within the Berber homeland a local, more particular term, such as Kabyle or Chaoui, is more often used instead.[6] Historically Berbers have been variously known, for instance as Libyans by the ancient Greeks,[7] as Numidians and Mauri by the Romans, and as Moors by medieval and early modern Europeans. The modern English term is borrowed from Arabic, but the deeper etymology of "Berber" is not certain. (See also: Berber (Etymology).)
The best known of them were the Pharaoh Ramses II,[8] the Roman author Apuleius, the Roman emperor Septimius Severus, and Saint Augustine of Hippo.[9] A famous Berber living today is the International football star Zinedine Zidane.

Berbers are a group of peoples who have been living in Northern Africa since 3000 BP and speak different dialects, related to a common Chamito-Semitic language, Berber, aka Tamazight.
The Berbers call themselves Imazighen (The Free Men). The name Berber was derived from Barbarian during the Greco-Roman period. The Tuaregs have kept the original Berber alphabet, the tifinagh while other Berbers use either Latin or Arabic alphabet to write Tamazight.
According to the Dictionnaire des Peuples (Larousse), there are more than 20 millions of Berber-speaking people scattered over Northern Africa as follows:
Morocco:  70% of the country population. Rifains live on the northern coast, Imazighens and Chleuhs in the center and south of the country;
Mauritania: 12-25,000 Zenagas, living south of Nouakchott, close to the border with Senegal;
Algeria: 20-25% of the country population). Kabyles live in the north of the country close to Algiers, Chaouis close to the border with Tunisia, Zenets and Mozabits more in the south. Tuaregs are nomadic Berbers;
Tunisia: 60-90,000 people;
Libya: 300-550,000 people;
Egypt: 10-20,000 people, living in the oasis of Siwa and speaking Tasiwit, a Berber language including 40% of words taken from Egyptian dialects;
Another 2 millions of Tuaregs are scattered over Mali, Burkina Faso and Niger.
