Genetic History Of Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the 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 (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead grouped with the definition of MENA (i.e. Middle East–North Africa) as it is part of the ...

United Nations
The United Nations (UN) is an intergovernmental organization whose stated purposes are to maintain international peace and international security, security, develop friendly relations among nations, achieve international cooperation, and be a centre for harmonizing the actions of nations. It is the world's largest and most familiar international organization. The UN is headquarters of the United Nations, headquartered on extraterritoriality, international territory in New York City, and has other main offices in United Nations Office at Geneva, Geneva, United Nations Office at Nairobi, Nairobi, United Nations Office at Vienna, Vienna, and Peace Palace, The Hague (home to the International Court of Justice). The UN was established after World War II with Dumbarton Oaks Conference, the aim of preventing future world wars, succeeding the League of Nations, which was characterized as ineffective. On 25 April 1945, 50 governments met in San Francisco for United Nations Conference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luanda
Luanda () is the capital and largest city in Angola. It is Angola's primary port, and its major industrial, cultural and urban centre. Located on Angola's northern Atlantic coast, Luanda is Angola's administrative centre, its chief seaport, and also the capital of the Luanda Province. Luanda and its metropolitan area is the most populous Portuguese-speaking capital city in the world and the most populous Lusophone city outside Brazil, with over 8.3 million inhabitants in 2020 (a third of Angola's population). Among the oldest colonial cities of Africa, it was founded in January 1576 as ''São Paulo da Assunção de Loanda'' by Portuguese explorer Paulo Dias de Novais. The city served as the centre of the slave trade to Brazil before its prohibition. At the start of the Angolan Civil War in 1975, most of the white Portuguese left as refugees, principally for Portugal. Luanda's population increased greatly from refugees fleeing the war, but its infrastructure was inadequate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Ethnic Groups Of Africa
The ethnic groups of Africa number in the thousands, with each population generally having its own language (or dialect of a language) and culture. The ethnolinguistic groups include various Afroasiatic, Khoisan, Niger-Congo, and Nilo-Saharan populations. The official population count of the various ethnic groups in Africa is highly uncertain, both due to limited infrastructure to perform censuses and due to the rapid population growth. There have also been accusations of deliberate misreporting in order to give selected ethnicities numerical superiority (as in the case of Nigeria's Hausa, Fulani, Yoruba, and Igbo peoples). A 2009 genetic clustering study, which genotyped 1327 polymorphic markers in various African populations, identified six ancestral clusters. The clustering corresponded closely with ethnicity, culture and language. A 2018 whole genome sequencing study of the world's populations observed similar clusters among the populations in Africa. At K=9, distinct ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Top-level Domain
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last non empty label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is .com. Responsibility for management of most top-level domains is delegated to specific organizations by the ICANN, an Internet multi-stakeholder community, which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone. History Originally, the top-level domain space was organized into three main groups: ''Countries'', ''Categories'', and ''Multiorganizations''. An additional ''temporary'' group consisted of only the initial DNS domain, arpa, and was intended for transitional purposes toward the ...

Languages Of Africa
The languages of Africa are divided into several major language families: * Niger–Congo or perhaps Atlantic–Congo languages (includes Bantu and non-Bantu, and possibly Mande and others) are spoken in West, Central, Southeast and Southern Africa. *Afroasiatic languages are spread throughout Western Asia, North Africa, the Horn of Africa and parts of the Sahel. *Indo-European languages are spoken in South Africa and Namibia (Afrikaans, English, German) and are used as lingua francas in the former colonies of Britain and Liberia that was part of American Colonization Society (English), former colonies of France and of Belgium ( French), former colonies of Portugal (Portuguese), former colonies of Italy (Italian), former colonies of Spain (Spanish) and the current Spanish territories of Ceuta, Melilla and the Canary Islands and the current French territories of Mayotte and La Réunion. *Various families of Nilo-Saharan languages (unity debated) are spoken from Tanza ...

Irreligion
Irreligion or nonreligion is the absence or rejection of religion, or indifference to it. Irreligion takes many forms, ranging from the casual and unaware to full-fledged philosophies such as atheism and agnosticism, secular humanism and antitheism. Social scientists tend to define irreligion as a purely naturalist worldview that excludes a belief in anything supernatural. The broadest and loosest definition, serving as an upper limit, is the lack of religious identification, though many non-identifiers express metaphysical and even religious beliefs. The narrowest and strictest is subscribing to positive atheism. According to the Pew Research Center's 2012 global study of 230 countries and territories, 16% of the world's population does not identify with any religion. The population of the religiously unaffiliated, sometimes referred to as "nones", has grown significantly in recent years. Measurement of irreligiosity requires great cultural sensitivity, especially outsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Islam In Africa
Islam in Africa is the continent's second most widely professed faith behind Christianity. Africa was the first continent into which Islam spread from Southwest Asia, during the early 7th century CE. Almost one-third of the world's Muslim population resides in Africa. Muslims crossed current Djibouti and Somalia to seek refuge in present-day Eritrea and Ethiopia during the ''Hijrah'' ( ar, هِـجْـرَة, 'Migration') to the Christian Kingdom of Aksum. Like the vast majority (90%) of Muslims in the world, most Muslims in Africa are also Sunni Muslims; the complexity of Islam in Africa is revealed in the various schools of thought, traditions, and voices in many African countries. Many African ethnicities, mostly in North, West and East Africa consider Islam their Traditional religion. The practice of Islam on the continent is not static and is constantly being reshaped by prevalent social, economic, and political conditions. Generally Islam in Africa often adapted to Afric ...

Christianity In Africa
Christianity in Africa first arrived in Egypt in approximately 50 AD, reached the region around Carthage by the end of the second century. In the 4th century, the Aksumite empire in modern-day Ethiopia and Eritrea became one of the first regions in the world to adopt Christianity as their official religion. The Nubian kingdoms of Nobatia, Makuria and Alodia followed two centuries later. Important Africans who influenced the early development of Christianity include Tertullian, Perpetua, Felicity, Clement of Alexandria, Origen of Alexandria, Cyprian, Athanasius and Augustine of Hippo. The Islamic conquests into North Africa brought pressure on Christians to convert to Islam due to special taxation imposed on non-Muslims and other socio-economic pressures under Muslim rule. The Eastern Orthodox Church of Alexandria and Coptic Orthodox Church of Alexandria (which separated from each other during the Chalcedonian Schism) in Egypt and the Orthodox Tewahedo Church (that split into Et ...

United Nations High Commissioner For Refugees
The United Nations High Commissioner for Refugees (UNHCR) is a United Nations agency mandated to aid and protect refugees, forcibly displaced communities, and stateless people, and to assist in their voluntary repatriation, local integration or resettlement to a third country. It is headquartered in Geneva, Switzerland, with over 17,300 staff working in 135 countries. Background UNHCR was created in 1950 to address the refugee crisis that resulted from World War II. The 1951 Refugee Convention established the scope and legal framework of the agency's work, which initially focused on Europeans uprooted by the war. Beginning in the late 1950s, displacement caused by other conflicts, from the Hungarian Uprising to the decolonization of Africa and Asia, broadened the scope of UNHCR's operations. Commensurate with the 1967 Protocol to the Refugee Convention, which expanded the geographic and temporal scope of refugee assistance, UNHCR operated across the world, with the bu ...
