Archaic Human Admixture With Modern Humans
Interbreeding between archaic and modern humans occurred during the Middle Paleolithic and early Upper Paleolithic. The interbreeding happened in several independent events that included Neanderthals and Denisovans, as well as several unidentified hominins. In Europe, Asia and North Africa, interbreeding between archaic humans and modern humans took place several times. The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans. Neanderthal-derived DNA has been found in the genomes of most contemporary populations, varying noticeably by region. It accounts for 1–4% of modern genomes for people outside Sub-Saharan Africa, although estimates vary, and either none or up to 0.3% for those in Sub-Saharan Africa. Cushitic and Semitic speaking populations from the Horn of Africa (such as Ethiopians), who derive a large portion of their ancestry from West Eurasian ...

Map Of Western Eurasia Showing Areas And Estimated Dates Of Possible Neandertal–modern Human Hybridization (in Red) Based On Fossil Samples From Indicated Sites
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowing humans t ...

Negrito
The term ''Negrito'' (; ) refers to several diverse ethnic groups who inhabit isolated parts of Southeast Asia and the Andaman Islands. Populations often described as Negrito include: the Andamanese peoples (including the Great Andamanese, the Onge, the Jarawas (Andaman Islands), Jarawa, and the Sentinelese) of the Andaman Islands, the Semang peoples (among them, the Batek people) of Peninsular Malaysia, the Maniq people of Southern Thailand, as well as the Aeta people, Aeta of Luzon, the Ati people, Ati and Suludnon, Tumandok of Panay, the Mamanwa of Mindanao, and about 30 other officially recognized ethnic groups in the Philippines. Etymology The word ''Negrito,'' the Spanish diminutive of ''negro'', is used to mean "little black person." This usage was coined by 16th-century Spanish Catholic Church and the Age of Discovery, missionaries operating in the Philippines, and was borrowed by other European travellers and colonialists across Austronesia to label various peoples pe ...

Oceanian
Oceania ( , ) is a geographical region including Australasia, Melanesia, Micronesia, and Polynesia. Outside of the English-speaking world, Oceania is generally considered a continent, while Mainland Australia is regarded as its continental landmass. Spanning the Eastern and Western hemispheres, at the centre of the water hemisphere, Oceania is estimated to have a land area of about and a population of around 46.3 million as of 2024. Oceania is the smallest continent in land area and the second-least populated after Antarctica. Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia, French Polynesia, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much less developed economies of Kiribati, Papua New Guinea, Tuvalu, Vanuatu, and Western New Guinea. The largest and most populous country in Oceania is Australia, and the largest city is Sydney. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western 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 ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Indigenous Peoples Of The Americas
In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized city, cities, city-states, chiefdoms, state (polity), states, monarchy, kingdoms, republics, confederation, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as Pre-Columbian engineering in the Americas, engineering, Pre-Columbian architecture, architecture, mathematics, astronomy, History of writing, writing, physics, medicine, Pre-Columbian agriculture, agriculture, irrigation, geology, minin ...

Genetic Admixture
Genetic admixture occurs when previously isolated populations interbreed resulting in a population that is descended from multiple sources. It can occur between species, such as with hybrids, or within species, such as when geographically distant individuals migrate to new regions. It results in gene pool that is a mix of the source populations. Examples Climatic cycles facilitate genetic admixture in cold periods and genetic diversification in warm periods. Natural flooding can cause genetic admixture within populations of migrating fish species. Genetic admixture may have an important role for the success of populations that colonise a new area and interbreed with individuals of native populations. Mapping Admixture mapping is a method of gene mapping that uses a population of mixed ancestry (an admixed population) to find the genetic loci that contribute to differences in diseases or other phenotypes found between the different ancestral populations. The method is best app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polynesians
Polynesians are an ethnolinguistic group comprising closely related ethnic groups native to Polynesia, which encompasses the islands within the Polynesian Triangle in the Pacific Ocean. They trace their early prehistoric origins to Island Southeast Asia and are part of the larger Austronesian ethnolinguistic group, with an Urheimat in Taiwan. They speak the Polynesian languages, a branch of the Oceanic subfamily within the Austronesian language family. The Indigenous Māori people form the largest Polynesian population, followed by Samoans, Native Hawaiians, Tahitians, Tongans, and Cook Islands Māori. , there were an estimated 2 million ethnic Polynesians (both full and part) worldwide. The vast majority either inhabit independent Polynesian nation-states (Samoa, Niue, Cook Islands, Tonga, and Tuvalu) or form minorities in countries such as Australia, Chile (Easter Island), New Zealand, France (French Polynesia and Wallis and Futuna), and the United States (Hawaii and Am ...

Melanesians
Melanesians are the predominant and Indigenous peoples of Oceania, indigenous inhabitants of Melanesia, in an area stretching from New Guinea to the Fiji Islands. Most speak one of the many languages of the Austronesian languages, Austronesian language family (especially ones in the Oceanic languages, Oceanic branch) or one of the many unrelated families of Papuan languages. There are several creoles of the region, such as Tok Pisin, Hiri Motu, Pijin language, Solomon Islands Pijin, Bislama, and Papuan Malay. Origin and genetics The origin of Melanesians is generally associated with the first settlement of Australasia by a lineage dubbed 'Australasians' or 'Australo-Papuans' during the Initial Upper Paleolithic, which is "ascribed to a population movement with uniform genetic features and material culture" (Ancient East Eurasians), and sharing deep ancestry with modern East Asian people, East Asian peoples and other Asia-Pacific groups. It is estimated that people reached Austral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Europeans
Europeans are the focus of European ethnology, the field of anthropology related to the various ethnic groups that reside in the states of Europe. Groups may be defined by common ancestry, language, faith, historical continuity, etc. There are no universally accepted and precise definitions of the terms "ethnic group" and "nationality", but in the context of European ethnography in particular, the terms ''ethnic group'', ''people'', ''nationality'' and ''ethno-linguistic group'' are used as mostly synonymous. Preference may vary in usage with respect to the situation specific to the individual countries of Europe, and the context in which they may be classified by those terms. The total number of national minority populations in Europe is estimated at 105 million people, or 14% of 770 million Europeans in 2002.Christoph Pan, Beate Sibylle Pfeil (2002), Minderheitenrechte in Europa.
