Haplogroup L0 (mtDNA)
Haplogroup L0 is a human mitochondrial DNA (mtDNA) haplogroup. Origin L0 is one of two branches from the most recent common ancestor (MRCA) for the shared human maternal lineage. The haplogroup consists of five main branches (L0a, L0b, L0d, L0f, L0k). Four of them were originally classified into L1 subclades, L1a, L1d, L1f and L1k. In 2014, ancient DNA analysis of a 2,330 year old male forager's skeleton in Southern Africa found that the specimen belonged to the L0d2c1c mtDNA subclade. This maternal haplogroup is today most closely associated with the Ju, a subgroup of the indigenous San people, which points to population continuity in the region. In 2016, a Late Iron Age desiccated mummy from the Tuli region in northern Botswana was also found to belong to haplogroup L0. Distribution L0 is found most commonly in Sub-Saharan Africa. It reaches its highest frequency in the Khoisan people at 73% on average. Some of the highest frequencies are: Namibia ( !Xun) 79%, South Africa ...

Human Mitochondrial DNA Haplogroup
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe. The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships. The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve. The rate at which mitochondrial DNA mutates is known as the mitochon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
95% CI
In frequentist statistics, a confidence interval (CI) is a range of estimates for an unknown parameter. A confidence interval is computed at a designated ''confidence level''; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used. The confidence level represents the long-run proportion of corresponding CIs that contain the true value of the parameter. For example, out of all intervals computed at the 95% level, 95% of them should contain the parameter's true value. Factors affecting the width of the CI include the sample size, the variability in the sample, and the confidence level. All else being the same, a larger sample produces a narrower confidence interval, greater variability in the sample produces a wider confidence interval, and a higher confidence level produces a wider confidence interval. Definition Let be a random sample from a probability distribution with statistical parameter , which is a quantity to be estimated ...

African Pygmies
The African Pygmies (or Congo Pygmies, variously also Central African foragers, "African rainforest hunter-gatherers" (RHG) or "Forest People of Central Africa") are a group of ethnicities native to Central Africa, mostly the Congo Basin, traditionally subsisting on a forager and hunter-gatherer lifestyle. They are divided into three roughly geographic groups: *the western ''Bambenga'', or ''Mbenga'' (Cameroon, Gabon, Republic of the Congo, Central African Republic), *the eastern ''Bambuti'', or ''Mbuti'', of the Congo basin (DRC) *the central and southern ''Batwa'', or ''Twa'' (Rwanda, Burundi, DRC, Tanzania, Uganda, Zambia, Angola and Namibia). The more widely scattered (and more variable in physiology and lifestyle) Southern Twa are also grouped under the term Pygmoid. They are notable for, and named for, their short stature (described as "pygmyism" in anthropological literature). They are assumed to be descended from the original Middle Stone Age expansion of anatomically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mbuti
The Mbuti people, or Bambuti, are one of several indigenous pygmy groups in the Congo region of Africa. Their languages are Central Sudanic languages and Bantu languages. Subgroups Bambuti are pygmy hunter-gatherers, and are one of the oldest indigenous people of the Congo region of Africa. The Bambuti are composed of bands which are relatively small in size, ranging from 15 to 60 people. The Bambuti population totals about 30,000 to 40,000 people. Many Batwa in various parts of the DRC call themselves Bambuti as well. There are three distinct subgroups: * The Sua (also Kango, or Mbuti), who speak a dialect (or perhaps two) of the language of a neighboring Bantu people, Bila. They are located centrally and are eponymous of the larger group. * The Efé, who speak the language of the neighboring Central Sudanic Lese. * The Asua, speakers of the Mangbetu (Central Sudanic) Asua language.

Balanta People
The Balanta (Guinea-Bissau Creole and Portuguese: ''balanta''; ; lit. “those who resist” in Mandinka) are an ethnic group found in Guinea-Bissau, Guinea, Senegal, Cape Verde and The Gambia. They are the largest ethnic group of Guinea-Bissau, representing more than one-quarter of the population. Despite their numbers, they have remained outside the colonial and postcolonial state because of their social organisation. The Balanta can be divided into six clans: Nhacra, Ganja (Mane), Naga, Patch, Sofa and Kentohe. The largest of which are the Balanta Kentohe. Archaeologists believe that the people who became the Balanta migrated to present-day Guinea-Bissau in small groups between the 10th and 14th centuries CE. During the 19th century, they spread throughout the area that is now Guinea-Bissau and southern Senegal in order to resist the expansion of the Kaabu kingdom. Today, the Balanta are found in the modern-day countries of Senegal, Cape Verde and Gambia but mostly reside in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and language. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of t ...

Sandawe People
The Sandawe are an indigenous ethnic group of Southeast Africa, based in the Chemba District of Dodoma Region in central Tanzania. In 2000, the Sandawe population was estimated to be 40,000. The Sandawe language is a tonal language that uses click consonants, as do the Khoe languages of southern Africa. There is no other proven connection between the two. History Origins Although the Khoisan were originally thought to possess the oldest human DNA lineages, those of the Sandawe are older. This suggests southern Khoisan originated in East Africa. The Sandawe today are considered descendants of an original Bushmen-like people, unlike their modern neighbours, the Gogo. They live in the geographic centre of old German East Africa, the 'Street of Caravans' crossing their southern edge. The Sandawe language may share a common ancestor with the Khoe languages of southern Africa. It has clicks and the surrounding Bantu peoples find it difficult to learn. It is unrelated to the nei ...

East Africa, Eastern Africa, or East of Africa, is the eastern subregion of the African continent. In the United Nations Statistics Division scheme of geographic regions, 10-11-(16*) territories make up Eastern Africa: Due to the historical Omani Empire and colonial territories of the British East Africa Protectorate and German East Africa, the term ''East Africa'' is often (especially in the English language) used to specifically refer to the area now comprising the three countries of Kenya, Tanzania, and Uganda. However, this has never been the convention in many other languages, where the term generally had a wider, strictly geographic context and therefore typically included Djibouti, Eritrea, Ethiopia, and Somalia.Somaliland is not included in the United Nations geoscheme, as it is internationally recognized as a part of Somalia. *Tanzania, Kenya, Uganda, Rwanda, Burundi, Democratic Republic of Congo and South Sudan are members of the East African Community.
