The genetic history of North Africa encompasses the genetic history of the people of North Africa.The most important source of gene flow to North Africa from the Neolithic Era onwards was from Western Asia, while the Sahara desert to the south and the Mediterranean Sea to the north were also important barriers to gene flow from sub-Saharan Africa and parts of Europe in prehistory.
West Africans (e.g., Mende of Sierra Leone), bearing the Senegal sickle cell haplotype, [112] [97] may have migrated into Mauritania (77% modern rate of occurrence) and Senegal (100%); they may also have migrated across the Sahara, into North Africa, and from North Africa, into Southern Europe, Turkey, and a region near northern Iraq and ...
An investigation in 2012 discovered that unlike most sub-Saharan Africans, North Africans have similar levels of Neanderthal DNA to South Europeans and West Asians, which is pre-Neolithic in origin, rather than via any recent admixture, as the Neanderthal's genetic signals were higher in populations with an autochthonous 'back-to-Africa' genomic component that arrived 12,000 years ago.
Another subclade, E3b1b-M81 is associated with Berber populations and is commonly found in regions that have had historical gene flow with northern Africa, such as the Iberian Peninsula, the Canary Islands, and Sicily. [35] North African Y-DNA E-M81 was found at a total of 41.1% among "pasiegos" from Cantabria, Spain. That is the highest ...
Although less parsimonious than recent gene flow, the observation may have been due to ancient population sub-structure in Africa, causing incomplete genetic homogenization within modern humans when Neanderthals diverged while early ancestors of Eurasians were still more closely related to Neanderthals than those of Africans were to ...
E-M215 or E1b1b, formerly known as E3b, is a major human Y-chromosome DNA haplogroup.E-M215 has two basal branches, E-M35 and E-M281. E-M35 is primarily distributed in North Africa and the Horn of Africa, and occurs at moderate frequencies in the Middle East, Europe, and Southern Africa.
Listed here are the human Y-chromosome DNA haplogroups found in various ethnic groups and populations from North Africa and the Sahel . By population Population ...
Gene flow is the transfer of alleles from one population to another population through immigration of individuals. In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent ...
