Genetic History Of Africa
The genetic history of Africa is composed of the overall genetic history of Demographics of Africa, 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 African origin of modern humans, 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 Interstadial, humid phases and periods throughout the history of Africa. Overview The Demographics of Africa, peoples of Africa are characterized by regional genetic substructure and heterogeneity, depending on the respective ethno-linguistic identity, and, in part, explainable by the "multiregional evolution" of modern human lineages in various multiple regions of the African continent, as well as later admixture events, including back-migrations from Eurasia, of both highly differentiated West- and East-Eurasian components.

Bantu Expansion
The Bantu expansion is a hypothesis about the history of the major series of migrations of the original Proto-Bantu-speaking group, which spread from an original nucleus around Central Africa across much of sub-Saharan Africa. In the process, the Proto-Bantu-speaking settlers displaced or absorbed pre-existing hunter-gatherer and pastoralist groups that they encountered. The primary evidence for this expansion is linguistic – a great many of the languages which are spoken across Sub-Equatorial Africa are remarkably similar to each other, suggesting the common cultural origin of their original speakers. The linguistic core of the Bantu languages, which comprise a branch of the Atlantic-Congo language family, was located in the southern regions of Cameroon. However, attempts to trace the exact route of the expansion, to correlate it with archaeological evidence and genetic evidence, have not been conclusive; thus although the expansion is widely accepted as having taken place, ...

Niger–Congo Languages
Niger–Congo is a hypothetical language family spoken over the majority of sub-Saharan Africa. It unites the Mande languages, the Atlantic-Congo languages (which share a characteristic noun class system), and possibly several smaller groups of languages that are difficult to classify. If valid, Niger-Congo would be the world's largest in terms of member languages, the third-largest in terms of speakers, and Africa's largest in terms of geographical area.Irene Thompson"Niger-Congo Language Family" "aboutworldlanguages", March 2015 It is generally considered to be the world's largest language family in terms of the number of distinct languages, just ahead of Austronesian, although this is complicated by the ambiguity about what constitutes a distinct language; the number of named Niger–Congo languages listed by ''Ethnologue'' is 1,540. If valid, it would be the third-largest language family in the world by number of native speakers, comprising around 700 million people as of ...

Indigenous Peoples Of Africa
The indigenous people of Africa are groups of people native to a specific region; people who lived there before colonists or settlers arrived, defined new borders, and began to occupy the land. This definition applies to all indigenous groups, whether inside or outside of Africa. Although the vast majority of Native Africans can be considered to be "indigenous" in the sense that they originated from that continent and nowhere else (like all Homo sapiens sapiens), identity as an "indigenous people" is in modern application more restrictive. Not every African ethnic group claims identification under these terms. Groups and communities who do claim this recognition are those who by a variety of historical and environmental circumstances have been placed outside of the dominant state systems. Their traditional practices and land claims often have come into conflict with the objectives and policies promulgated by governments, companies and surrounding dominant societies. Marginalizati ...

Overall Genetic Position Of Worldwide Populations
Overalls, also called bib-and-brace overalls or dungarees, are a type of garment usually used as protective clothing when working. The garments are commonly referred to as a "pair of overalls" by analogy with "pair of trousers". Overalls were originally made of denim, but they can also be made of corduroy, chino cloth, or Leather to name a few. Overalls were invented in the mid to late 1890s by Grace Howard and Jacob W. Davis at Levi Strauss & Co., but they went through an evolution to reach their modern form. Initially only used for protective clothing in work settings, such as farming, welding, working in oil fields, ext. They have also become a garment of high fashion as "potential cult items". Many high fashion brands have released their own spin on overalls. History Beginnings The exact beginnings of the wearing of overalls are unclear, but they are mentioned in literature as early as 1776 as protective working garments commonly worn by slaves.

East Asian People
East Asian people (East Asians) are the people from East Asia, which consists of China, Taiwan, Japan, Mongolia, North Korea, and South Korea. The total population of all countries within this region is estimated to be 1.677 billion and 21% of the world's population in 2020. However, large East Asian diasporas, such as the Chinese, Japanese, Korean, and Mongolian diasporas, as well as diasporas of other East Asian ethnic groups, mean that the 1.677 billion does not necessarily represent an accurate figure for the numbers of East Asian people worldwide. The major ethnic groups that form the core of East Asia are the Chinese, Koreans, and Japanese. Other ethnic groups of East Asia include the Ainu, Bai, Manchus, Mongols and other Mongolic peoples, Nivkh, Qiang, Ryukyuans, Tibetans, and Yakuts. Culture The major East Asian language families are the Sinitic, Japonic, and Koreanic families. Other language families include the Tibeto-Burman, Ainu languages, Mongolic, Tungusic, ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Malagasy People
The Malagasy (french: Malgache) are an Austronesian-speaking African ethnic group native to the island country of Madagascar. Traditionally, the population have been divided by subgroups (tribes or ethnicities). Examples include "Highlander" (ethnically Austronesian/Malay-Indonesian with less Bantu ancestry) groups such as the Merina and Betsileo of the central highlands around Antananarivo, Alaotra ''(Ambatondrazaka)'' and Fianarantsoa, and the "coastal dwellers" (ethnically Bantu with less Austronesian ancestry) with tribes like the Sakalava, Bara, Vezo, Betsimisaraka, Mahafaly, etc. The Merina are also further divided into two subgroups. The “Merina A” are the Hova and Andriana, and have an average of 30–40% Bantu ancestry. The second subgroup is the “Merina B”, the Andevo, who have an average of 40-50% Bantu ancestry. They make up less than 1/3 of Merina society. The Malagasy population was 2,242,000 in the first census in 1900. Their population experienced a m ...

Nilo-Saharan Languages
The Nilo-Saharan languages are a proposed family of African languages spoken by some 50–60 million people, mainly in the upper parts of the Chari River, Chari and Nile rivers, including historic Nubia, north of where the two tributaries of the Nile meet. The languages extend through 17 nations in the northern half of Africa: from Algeria to Benin in the west; from Libya to the Democratic Republic of the Congo in the centre; and from Egypt to Tanzania in the east. As indicated by its hyphenated name, Nilo-Saharan is a family of the African interior, including the greater Nile Basin and the Central Sahara Desert. Eight of its proposed constituent divisions (excluding Kunama languages, Kunama, Kuliak, and Songhai languages, Songhay) are found in the modern countries of Sudan and South Sudan, through which the Nile River flows. In his book ''The Languages of Africa'' (1963), Joseph Greenberg named the group and argued it was a genetic (linguistics), genetic family. It contains the ...

Afroasiatic Languages
The Afroasiatic languages (or Afro-Asiatic), also known as Hamito-Semitic, or Semito-Hamitic, and sometimes also as Afrasian, Erythraean or Lisramic, are a language family of about 300 languages that are spoken predominantly in the geographic subregions of Western Asia, North Africa, the Horn of Africa, and parts of the Sahara/Sahel. With the exception of its Semitic branch, all branches of the Afroasiatic family are exclusively native to the African continent. Afroasiatic languages have over 500 million native speakers, which is the fourth-largest number of native speakers of any language family (after Indo-European, Sino-Tibetan, and Niger–Congo). The phylum has six branches: Berber, Chadic, Cushitic, Egyptian, Semitic, and Omotic. The most widely spoken modern Afroasiatic language or dialect continuum by far is Arabic, a ''de facto'' group of distinct language varieties within the Semitic branch. The languages that evolved from Proto-Arabic have around 313 million na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
