The Oromo people are a Cushitic ethnic group native to the Oromia region of Ethiopia and parts of Northern Kenya. They speak the Oromo language, which is part of the Cushitic branch of the Afroasiatic language family. They are one of the largest ethnic groups in Ethiopia. According to the last Ethiopian census of 2007, the Oromo numbered 25,488,344 people or 34.5% of the Ethiopian population. Recent estimates have the Oromo comprising 41,000,000 people, or 35.8% of the total Ethiopian population estimated at 116,000,000.
The Nilotic peoples are people indigenous to the Nile Valley who speak Nilotic languages. They inhabit South Sudan, Sudan, Ethiopia, Uganda, Kenya, the eastern border area of Democratic Republic of the Congo, Rwanda, Burundi and Tanzania. Among these are the Burun-speaking peoples, Teso people also known as Iteso or people of Teso, Karo peoples, Luo peoples, Ateker peoples, Kalenjin peoples, Karamojong people also known as the Karamojong or Karimojong, Datooga, Dinka, Nuer, Atwot, Lotuko, and the Maa-speaking peoples.
The Rendille are a Cushitic ethnic group inhabiting the Eastern Province of Kenya.
The Kenya-Turbi City massacre was the killing of fifty-six people by feuding clans in the remote Marsabit District of Northern Kenya on the early morning of 12 July 2005. Hundreds of armed raiders of the Borana tribe attacked the Gabra people living in the Turbi area northwest of Marsabit. Twenty-two of the sixty confirmed dead were children, and over six thousand people fled their homes, most fleeing to Marsabit town. The massacre's aftermath sparked several violent inter-clan conflicts, raising the death toll to ninety-five.
The Garre are a prominent Somali clan that traces its lineage back to Samaale, who is believed to have originated from the Arabian Peninsula through Aqiil Abu Talib. The Garre clan is considered to be a sub-clan of the Digil-Rahanweyn clan family, which is part of the larger Rahanweyn clan. However, genealogically, they are descended from Gardheere Samaale. The Garre are also categorized as southern Hawiye as well.
Haplogroup L3 is a human mitochondrial DNA (mtDNA) haplogroup. The clade has played a pivotal role in the early dispersal of anatomically modern humans.
Ethiopians are the native inhabitants of Ethiopia, as well as the global diaspora of Ethiopia. Ethiopians constitute several component ethnic groups, many of which are closely related to ethnic groups in neighboring Eritrea and other parts of the Horn of Africa.
The Iraqw People are a Cushitic ethnic group inhabiting the northern Tanzanian regions. They are believed to have originated from the southwestern Arusha and Manyara regions of Tanzania, near the Rift Valley. The Iraqw people then settled in the southeast of Ngorongoro Crater in northern Karatu District, Arusha Region, where the majority of them still reside. In the Manyara region, the Iraqw are a major ethnic group, specifically in Mbulu District, Babati District and Hanang District.
The Sakuye are people living in Marsabit, Tana River, Mandera and Isiolo counties, as well as the Northern Frontier District.
The Konso, also known as the Xonsita, are a Lowland East Cushitic-speaking ethnic group primarily inhabiting south-western Ethiopia.
Haplogroup E-V68, also known as E1b1b1a, is a major human Y-chromosome DNA haplogroup found in North Africa, the Horn of Africa, Western Asia and Europe. It is a subclade of the larger and older haplogroup, known as E1b1b or E-M215. The E1b1b1a lineage is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome, which is known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.
The Proto-Afroasiatic homeland is the hypothetical place where speakers of the Proto-Afroasiatic language lived in a single linguistic community, or complex of communities, before this original language dispersed geographically and divided into separate distinct languages. Afroasiatic languages are today mostly distributed in parts of Africa, and Western Asia.
The proportions of various human Y-DNA haplogroups vary significantly from one ethnic or language group to another in Africa.
E-Z827, also known as E1b1b1b, is a major human Y-chromosome DNA haplogroup. It is the parent lineage to the E-Z830 and E-V257 subclades, and defines their common phylogeny. The former is predominantly found in the Middle East; the latter is most frequently observed in North Africa, with its E-M81 subclade observed among the ancient Guanche natives of the Canary Islands. E-Z827 is also found at lower frequencies in Europe, and in isolated parts of Southeast Africa.
The genetic history of Egypt reflects its geographical location at the crossroads of several major biocultural areas: North Africa, the Sahara, the Middle East, the Mediterranean and sub-Saharan Africa.
The El Molo, also known as Elmolo, Dehes, Fura-Pawa and Ldes, are an ethnic group mainly inhabiting the northern Eastern Province of Kenya. They historically spoke the El Molo language as a mother tongue, an Afro-Asiatic language of the Cushitic branch, and now most El Molo speak Samburu.
HaplogroupGHIJK, defined by the SNPs M3658, F1329, PF2622, and YSC0001299, is a common Y-chromosome haplogroup. This macrohaplogroup and its subclades contain the vast majority of the world's existing male population.
The human Y-chromosome haplogroup E-V12 is a subclade of E-M78, which in turn is part of the larger haplogroup E1b1b1. According to Cruciani et al. (2007), the E-V12 sublineage likely originated in Northern Africa. It has two main branches: E-V32 which is most common in the Horn of Africa, and E-CTS693 which is most common in Upper Egypt and to a lesser extent in Sudan. E-CTS693 is also scattered in low frequencies across the Levant, Anatolia, the Central Sahel, the African Great Lakes region, and Europe.
Worr Libin was an alliance of Cushitic-speaking population groups that inhabited various regions of northern Kenya and southern Ethiopia. It has been argued that the adoption of the Borana language by the other Somaloid Worr Libin groups reflected their acceptance of a regional Boran political hegemony. This period is thought to have lasted from 1550-1920.
The genetic history of Africa is composed of the overall genetic history of African populations in Africa, including the regional genetic histories of North Africa, West Africa, East Africa, Central Africa, and Southern Africa, as well as the recent origin of modern humans in Africa. The Sahara served as a trans-regional passageway and place of dwelling for people in Africa during various humid phases and periods throughout the history of Africa.
