Ifri N'Amr Or Moussa
Ifri n'Amr Ou Moussa is an archaeological site discovered in 2005, located in the rural commune of Aït Siberne, Khémisset Province, in Western Morocco. This site has revealed burials associated with both Moroccan Early Neolithic and Bell Beaker culture. Genetics examined the remains of 7 individuals buried at Ifri N'Amr Ou Moussa (c. 5325-4786 BCE). The 2 samples of Y-DNA extracted belonged to the paternal haplogroup E-L19*, while the 5 samples of mtDNA extracted belonged to the maternal haplogroups M1b1*, U6a1b (two samples), U6a7b2 and U6a3. The paternal haplogroup E-L19* is very common in North Africa, and the maternal haplogroups are associated with migrations from Eurasia into North Africa during the Upper Paleolithic. They were found to be closely related to the early Stone Age people buried at Taforalt, Morocco (c. 15000 BCE). Both the Taforalt and Ifri N'Amr ou Moussa people were found to also be related to people of the Natufian culture (c. 12000 BCE) and Pre-Pott ...

Ait Siberne
Ait Siberne is a commune in the Khémisset Province of the Rabat-Salé-Kénitra administrative region of Morocco Morocco, officially the Kingdom of Morocco, is a country in the Maghreb region of North Africa. It has coastlines on the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria to Algeria–Morocc .... At the 2004 census, the commune had a total population of 5,232 people living in 1001 households. It is now considered a universal patrimony region because of its prehistorical sites.

Kelif El Boroud
Kehf el Baroud, sometimes mistakenly spelled Kelif el Boroud, is an archaeological site in Morocco. It is located to the south of Rabat, near the Aterian industry of Dar es Soltan. Genetics examined the remains of 8 individuals buried at Kelif el Boroud (c. 3780-3650 BCE) during the Late Neolithic. The 1 sample of Y-DNA extracted belonged to the paternal haplogroup T-M184, while the 6 samples of mtDNA extracted belonged to the maternal haplogroups X2b (two samples), K1a1b1 (two samples), K1a4a1 and lastly T2b3, with the other being undetermined. The examined individuals were found to share genetic affinities with individuals buried at both the Early Neolithic sites of Ifri N'Amr Ou Moussa in Morocco and the Early Neolithic Cave of El Toro in Spain. They were modelled as being of about 50% Early European Farmer (EEF) ancestry and 50% local North African (IAM) ancestry, suggesting substantial migration from Iberia into North Africa during the Neolithic era of human his ...

5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. Humans, and many other animals, have 5 digits on their limbs. Mathematics 5 is a Fermat prime, a Mersenne prime exponent, as well as a Fibonacci number. 5 is the first congruent number, as well as the length of the hypotenuse of the smallest integer-sided right triangle, making part of the smallest Pythagorean triple ( 3, 4, 5). 5 is the first safe prime and the first good prime. 11 forms the first pair of sexy primes with 5. 5 is the second Fermat prime, of a total of five known Fermat primes. 5 is also the first of three known Wilson primes (5, 13, 563). Geometry A shape with five sides is called a pentagon. The pentagon is the first regular polygon that does not tile the plane with copies of itself.

Mechta-Afalou
Mechta-Afalou, also known as Mechtoid or Paleo-Berber, are a population that inhabited parts of North Africa during the late Paleolithic and Mesolithic. They are associated with the Iberomaurusian archaeological culture. The name Mechta-Afalou comes from the large number of skeletons found in the Afalou bou Rhummel site in Béjaïa in Algeria. Ginette Aumassip. '' 4. L’homme de Mechta el-Arbi, dernier descendant de l’Atlanthrope ? '', in ''L'Algérie des premiers hommes''. Éditions de la Maison des sciences de l’homme. 31 March 2017. Bioanthropology Mechtoids are believed to have been assimilated during the Neolithic and early Bronze Age by the makers of the ensuing Capsian culture. In 1999, the anthropologists Colin Groves & Alan Thorne in studying three Northern African samples from the Pleistocene/Holocene, found Taforalt was morphologically "Caucasoid" and resembled late Pleistocene Europeans, while Afalou was more intermediate in traits. In contrast to both, the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guanches
The Guanche were the Indigenous peoples, indigenous inhabitants of the Spain, Spanish Canary Islands, located in the Atlantic Ocean some to the west of modern Morocco and the North African coast. The islanders spoke the Guanche language, which is believed to have been related to the Berber languages of mainland North Africa; the language became extinct in the 17th century, soon after the islands were colonized. It is believed that the Guanche may have arrived at the archipelago some time in the 1st millennium BC, first millennium BC. The Guanche were the only indigenous people known to have lived in the Macaronesian archipelago region before the arrival of Europeans. There is no accepted evidence that the other Macaronesian archipelagos (the Cape Verde Islands, Madeira and the Azores) were inhabited. After the commencement of the Conquest of the Canary Islands, Spanish conquest of the Canaries, starting in the early 15th century, many natives were outright killed by the Spanish ...

Eye Color
Eye color is a polygene, polygenic phenotypic trait determined by two factors: the pigmentation of the eye's Iris (anatomy), iris and the frequency-dependence of the scattering of light by the Turbidity, turbid medium in the Stroma of iris, stroma of the iris. In humans, the pigmentation of the Iris (anatomy), iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue, green, and hazel eyes results from the Tyndall effect, Tyndall scattering of light in the stroma, a phenomenon similar to Rayleigh scattering which accounts for the blue sky. Neither blue nor green pigments are present in the human iris or vitreous humour. This is an example of structural color, which depends on the lighting conditions, especially for lighter-colored eyes. The brightly c ...

Dark Skin
Dark skin is a type of human skin color that is rich in melanin pigments. People with dark skin are often referred to as black people, although this usage can be ambiguous in some countries where it is also used to specifically refer to different ethnic groups or populations. The evolution of dark skin is believed to have begun around 1.2 million years ago, in light-skinned early hominid species after they moved from the equatorial rainforest to the sunny savannas. In the heat of the savannas, better cooling mechanisms were required, which were achieved through the loss of body hair and development of more efficient perspiration. The loss of body hair led to the development of dark skin pigmentation, which acted as a mechanism of natural selection against folate (vitamin B9) depletion, and to a lesser extent, Direct DNA damage, DNA damage. The primary factor contributing to the evolution of dark skin pigmentation was the breakdown of folate in reaction to ultraviolet radiat ...

Sub-Saharan Africa is the area and regions of the continent of Africa that lie south of the Sahara. These include Central Africa, East Africa, Southern Africa, and West Africa. Geopolitically, in addition to the list of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations geoscheme for Africa, United Nations (UN). This is considered a non-standardised geographical region with the number of countries included varying from 46 to 48 depending on the organisation describing the region (e.g. United Nations, UN, World Health Organization, WHO, World Bank, etc.).
