Haplogroup H (mtDNA)
Haplogroup H is a Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in West Asia, near present-day Syria, around 20,000 to 25,000 years ago. A specimen found in South Italy from 28000 years ago, in Paglicci Cave, was once believed to indicate haplogroup H, but researchers now recognize that CRS HVR1 also appears in U or HV, because there are no HVR1 mutations that separate CRS from the haplogroup R founder. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM). It first expanded in the northern Near East and Southern Caucasus, and later migrations from Iberia suggest that the clade reached Europe before the Last Glacial Maximum. The haplogroup has also spread from West Asia to parts of Africa, Siberia and Inner Asia. Today, around 40% of all maternal lineages in Europe belong to haplogroup H. Origin Haplogroup H is a descendant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
West Asia
West Asia (also called Western Asia or Southwest Asia) is the westernmost region of Asia. As defined by most academics, UN bodies and other institutions, the subregion consists of Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian highlands, the Levant, the island of Cyprus, the Sinai Peninsula and the South Caucasus. The region is separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. West Asia contains the majority of the similarly defined Middle East. The ''Middle East'' is a political term invented by Western geographers that has ...

HVR1
A hypervariable region (HVR) is a location within a sequence where polymorphisms frequently occur. It is used in two contexts: * In the case of nucleic acids, an HVR is where base pairs frequently change. This can be due to a change in the number of repeats (which is seen in eukaryotic nuclear DNA) or simply low selective pressure allowing a great number of substitutions and indels (as in the case of mitochondrial DNA D-loop and 16S rRNA). * In the case of antibodies, an HVR is where most of the differences among antibodies occur. This region is also called the complementarity-determining region. Because there already is a separate article for the antibody region, this article will focus on the nucleic acid case. Mitochondrial There are two mitochondrial hypervariable regions used in human mitochondrial genealogical DNA testing. HVR1 is considered a "low resolution" region and HVR2 is considered a "high resolution" region. Getting HVR1 and HVR2 DNA tests can help determine one ...

Central Asia
Central Asia is a region of Asia consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian language, Persian suffix "-stan" (meaning ) in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Volga Tatars, Tatars, Turkmens, ...

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

North Africa
North Africa (sometimes Northern Africa) is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region. However, it is sometimes defined as stretching from the Atlantic shores of the Western Sahara in the west, to Egypt and Sudan's Red Sea coast in the east. The most common definition for the region's boundaries includes Algeria, Egypt, Libya, Morocco, Tunisia, and Western Sahara, the territory territorial dispute, disputed between Morocco and the list of states with limited recognition, partially recognized Sahrawi Arab Democratic Republic. The United Nations’ definition includes all these countries as well as Sudan. The African Union defines the region similarly, only differing from the UN in excluding the Sudan and including Mauritania. The Sahel, south of the Sahara, Sahara Desert, can be considered as the southern boundary of North Africa. North Africa includes the Spanish cities of Ceuta and Melilla, and the ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait.

Makuria
Makuria ( Old Nubian: , ''Dotawo''; ; ) was a medieval Nubian kingdom in what is today northern Sudan and southern Egypt. Its capital was Dongola (Old Nubian: ') in the fertile Dongola Reach, and the kingdom is sometimes known by the name of its capital. Coming into being after the collapse of the Kingdom of Kush in the 4th century, it originally covered the Nile Valley from the 3rd cataract to somewhere south of Abu Hamed at Mograt Island. The capital of Dongola was founded around 500 and soon after, in the mid-6th century, Makuria converted to Christianity. Probably in the early 7th century Makuria annexed its northern neighbour Nobatia, now sharing a border with Byzantine Egypt. In 651 an Arab army invaded, but it was repulsed and a treaty known as the '' Baqt'' was signed to prevent further Arab invasions in exchange for 360 slaves each year. This treaty lasted until the 13th century. The period from the 9th to 11th century saw the peak of Makuria's cultural development ...

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 ...

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 ...

New Kingdom Of Egypt
The New Kingdom, also called the Egyptian Empire, refers to ancient Egypt between the 16th century BC and the 11th century BC. This period of History of ancient Egypt, ancient Egyptian history covers the Eighteenth Dynasty of Egypt, Eighteenth, Nineteenth Dynasty of Egypt, Nineteenth, and Twentieth Dynasty of Egypt, Twentieth dynasties. Through radiocarbon dating, the establishment of the New Kingdom has been placed between 1570 and 1544 BC. The New Kingdom followed the Second Intermediate Period of Egypt, Second Intermediate Period and was succeeded by the Third Intermediate Period of Egypt, Third Intermediate Period. It was the most prosperous time for the Egyptians#History, Egyptian people and marked the peak of Egypt's power. In 1845, the concept of a "New Kingdom" as Periodization of ancient Egypt, one of three "golden ages" was coined by German scholar Christian Charles Josias von Bunsen; the original definition would evolve significantly throughout the 19th and 20th ...
