[QUOTE]Originally posted by Troll Patrol: [QB] [QUOTE]Originally posted by Son of Ra: [qb] [QUOTE]Originally posted by the lioness,: [qb] Obvioulsy the Sahara is a barrier. You have to go back the holocene period for it not to be a barrier. Egypt is a different case because it runas along a river [/qb][/QUOTE][i]Using the Holocene biogeography and palaeohydrology of the Sahara as an analogue for the MIS5 humid period, it is likely that an interconnected waterway would have been available for faunal and human dispersal. [b]This humid period corresponds very closely with the age of the first modern human occupation of the North African coast (45) and the Levant (46) by sub-Saharan populations, who may have been crossing the Sahara at this time[/b] (9)." "Reanalysis of the Saharan zoogeography (SI Appendix, Section 1 and Table S1) suggests that many animals, including water-dependant creatures such as fish and amphibians, dispersed across the Sahara recently. For example, [b]25 North African animal species have a spatial distribution with population centers both north and south of the Sahara and small relict populations in central regions.[/b] This distribution suggests a trans-Saharan dispersal in the past, with subsequent local isolation of central Saharan populations during the more recent arid phase. [b]If a diverse range of species (including fish) can cross the Sahara, it is impossible to envisage the Sahara functioning as barrier to hominin dispersal."[/b][/i] Source: http://www.pnas.org/content/108/2/458.full.pdf [/qb][/QUOTE]Morocco is divided into 4 different feature of the natural landscape. [QUOTE] Rif Region The beautiful Rif is a mountain range that extends from Tangier in the west to the Moulouya River in the east and the Mediterranean sea in the north to the river of Ouargha in the south. The mountain region derives its name from the Berber word, arif. They belong to the Alboran Sea region but are not a part of the Atlas Mountains. The region is well known for its geographic diversity, as it is home to mountains, the sea, rivers, and hills. Major cities in the region are Nador, Al Hoceima, Ajdir and Taza, among others. The Rif was initially inhabited by the Berbers and was later invaded by the Phoenicians in the 3rd century BC, followed by the Romans and the Byzantines. The high plateau of Eastern Morocco: In the rain shadow region of the Atlas chain lies the broad valley of Moulouya. It stretches for about 530 kms rights from the Middle Atlas and goes right up to the Mediterranean Sea. Set to the southeast of the Atlas Mountains, this is a plateau formation at an altitude of 1300m (3900 feet). It stretches in the eastern direction to the Moroccan-Algerian border. It abruptly drops to the southwest and make a smoother transition toward the coastline. There are different small towns like Asni, Tin Mal that you can check out. The artificial lake Lalla Takerkoust created due the hydroelectric dam serves as a good source for the villages around it.
