Haplogroup L5
Haplogroup L5 is a human mitochondrial DNA (mtDNA) clade. It was previously known as L1e. Distribution L5 is a small haplogroup centered in East Africa. The highest frequency is in Mbuti Pygmies from Eastern Central Africa at 15%. It is present in relatively small frequencies in Tanzania ( Sandawe and others), Kenya, Chad, Ethiopia, Sudan, Nubia, EgyptSample UPE52 is subclade L5a. and Saudi Arabia. Haplogroup L5 has been observed among specimens at the island cemetery in Kulubnarti, Sudan Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopi ..., which date from the Early Christian period (AD 550–800). Subclades Tree This phylogenetic tree of haplogroup L5 subclades is based on the paper by Mannis van Oven and Manfred Kayser ''Updated comprehensive phylogenetic tree of global human ...

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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Africa
East Africa, also known as Eastern Africa or the East of Africa, is a region at the eastern edge of the Africa, African continent, distinguished by its unique geographical, historical, and cultural landscape. Defined in varying scopes, the region is recognized in the United Nations Statistics Division United Nations geoscheme for Africa, scheme as encompassing 18 sovereign states and 4 territories. It includes the Horn of Africa to the North and Southeastern Africa to the south. Definitions In a narrow sense, particularly in English-speaking contexts, East Africa refers to the area comprising Kenya, Tanzania, and Uganda, largely due to their shared history under the Omani Empire and as parts of the British East Africa Protectorate and German East Africa. Further extending East Africa's definition, the Horn of Africa—comprising Djibouti, Eritrea, Ethiopia, and Somalia—stands out as a distinct geopolitical entity within East Africa.Robert Stock, ''Africa South of the Sahara, ...

Nile
The Nile (also known as the Nile River or River Nile) is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The Nile is the longest river in Africa. It has historically been considered the List of river systems by length, longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer.Amazon Longer Than Nile River, Scientists Say Of the world's major rivers, the Nile has one of the lowest average annual flow rates. About long, its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. In pa ...

Haplogroup L2-6 (mtDNA)
In human mitochondrial genetics, L is the mitochondrial DNA macro-haplogroup that is at the root of the anatomically modern human (''Homo sapiens'') mtDNA phylogenetic tree. As such, it represents the most ancestral mitochondrial lineage of all currently living modern humans, also dubbed "Mitochondrial Eve". Its two sub-clades are L1-6 and L0. The split occurred during the Penultimate Glacial Period; L1-6 is estimated to have formed ca. 170 kya, and L0 ca. 150 kya. The formation of L0 is associated with the peopling of Southern Africa by populations ancestral to the Khoisan, ca. 140 kya, at the onset of the Eemian interglacial. L is further subdivided into L1-6 and L1, dated ca. 150 kya and 130 kya, respectively. Haplogroups L5 (120 kya), L2 and L6 (90 kya), L4 (80 kya) and L3 (70 kya). Origin The outgroup for mtDNA phylogeny of modern humans is the mtDNA of archaic humans, specifically Neanderthals and Denisovans. The split of the modern human lineage from t ...

Haplogroup L5a (mtDNA)
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the , ''haploûs'', "onefold, simple" and ) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy, in which each set (haplogroup) is also a subset of a sing ...

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 Democratic Republic of the Congo (DRC) also call themselves Bambuti. 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.

Pygmies
In anthropology, pygmy peoples are ethnic groups whose average height is unusually short. The term pygmyism is used to describe the phenotype of endemic short stature (as opposed to disproportionate dwarfism occurring in isolated cases in a population) for populations in which adult men are on average less than tall. Although the term is sometimes considered derogatory because it focuses on a physical trait, it remains the primary term associated with the African Pygmies, the hunter-gatherers of the Congo Basin (comprising the Bambenga, Bambuti and Batwa). The terms "Asiatic pygmies" and "Oceanic pygmies" have also been used to describe the Negrito populations of Southeast Asia and Australo-Melanesian peoples of short stature. The Taron people of Myanmar are an exceptional case of a pygmy population of East Asian phenotype. Etymology The term ''pygmy'', as used to refer to diminutive people, comes via Latin from Greek πυγμαῖος ''pygmaîos'', derived from Ï ...

Sandawe People
The Sandawe are an indigenous ethnic group of Southeast Africa, based in the Chemba District kwamtoro ward 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. History Origins There has been debate on whether the Sandawe represent a link to the Khoisan hunter-gatherers of Southern Africa, though recent research suggests Khoisan are older and mostly unrelated to Sandawe.Lorente-Galdos, B., Lao, O., Serra-Vidal, G. et al.

Kulubnarti
Kulubnarti ("Kulb island") is a long island in northern Sudan. Located on the Nile, around south of the Egyptian border, it is part of the village of Kulb. Until the fifteenth century, Kulubnarti was a remote area. It was one of the last known refuges for Christians in Nubia, while Islam spread to the south. It has been inhabited since the time of the Christian kingdom of Makuria, approximately 1100 AD. Continuously inhabited from the eleventh century to modern times, it is the only Nubian location which has demonstrated through archaeologically investigation a continuous occupation from the Middle Ages to modern history. Kulubnarti has archaeological and anthropological significance because it has been subjected to one of the only systematic excavations of any site along the southern portion of the Nile. The primary motivation for excavation at Kulubnarti was to increase awareness and understanding of the cultural transition from Christianity to Islam in ancient Nubia. Nubia con ...

Sudan
Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopia to the southeast, and South Sudan to the south. Sudan has a population of 50 million people as of 2024 and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's List of African countries by area, third-largest country by area and the third-largest by area in the Arab League. It was the largest country by area in Africa and the Arab League until the 2011 South Sudanese independence referendum, secession of South Sudan in 2011; since then both titles have been held by Algeria. Sudan's capital and most populous city is Khartoum. The area that is now Sudan witnessed the Khormusan ( 40000–16000 BC), Halfan culture ( 20500–17000 BC), Sebilian ( 13000–10000 BC), Qadan culture ( 15000–5000 BC), the war of Jebel ...
