Eurasian Backflow
The term ''Eurasian backflow'', or ''Eurasian back-migrations'', has been used to describe several pre-Neolithic and Neolithic migration events of humans from western Eurasia back to Africa. ''Homo sapiens'' had left Africa about 70-50,000 years ago, and between 30,000-15,000 years ago migrated back from the Middle East into Northern Africa. About 3,000 years ago, or already early between 9,000 to 6,000 years ago, farmers from Anatolia and the Near East migrated into the Horn of Africa. Signs of this migration can be found in the genomes of contemporary people from all over East Africa. Next to Eastern Africa, significant Eurasian ancestry is found in Northern Africa, and among specific ethnic groups of the Horn of Africa, as well as among the Malagasy people of Madagascar. Various genome studies found also evidence for multiple pre-Neolithic back-migrations from various Eurasian populations and subsequent admixture with native groups.

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malagasy People
The Malagasy (french: Malgache) are an Austronesian-speaking African ethnic group native to the island country of Madagascar. Traditionally, the population have been divided by subgroups (tribes or ethnicities). Examples include "Highlander" (ethnically Austronesian/Malay-Indonesian with less Bantu ancestry) groups such as the Merina and Betsileo of the central highlands around Antananarivo, Alaotra ''(Ambatondrazaka)'' and Fianarantsoa, and the "coastal dwellers" (ethnically Bantu with less Austronesian ancestry) with tribes like the Sakalava, Bara, Vezo, Betsimisaraka, Mahafaly, etc. The Merina are also further divided into two subgroups. The “Merina A” are the Hova and Andriana, and have an average of 30–40% Bantu ancestry. The second subgroup is the “Merina B”, the Andevo, who have an average of 40-50% Bantu ancestry. They make up less than 1/3 of Merina society. The Malagasy population was 2,242,000 in the first census in 1900. Their population experienced a m ...

Sardinian People
The Sardinians, or Sards ( sc, Sardos or ; Italian and Sassarese: ''Sardi''; Gallurese: ''Saldi''), are a Romance language-speaking ethnic group native to Sardinia, from which the western Mediterranean island and autonomous region of Italy derives its name. Etymology Not much can be gathered from the classical literature about the origins of the Sardinian people. The ethnonym "S(a)rd" belongs to the Pre-Indo-European linguistic substratum, and whilst they might have derived from the Iberians, the accounts of the old authors differ greatly in this respect. The oldest written attestation of the ethnonym is on the Nora stone, where the word ''Šrdn'' (''Shardan'') bears witness to its original existence by the time the Phoenician merchants first arrived to the Sardinian shores. According to Timaeus, one of Plato's dialogues, Sardinia and its people as well, the "Sardonioi" or "Sardianoi" (''Σαρδονιοί'' or ''Σαρδιανοί''), might have been named after "Sardò" ...

Neolithic
The Neolithic period, or New Stone Age, is an Old World archaeological period and the final division of the Stone Age. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. It began about 12,000 years ago when farming appeared in the Epipalaeolithic Near East, and later in other parts of the world. The Neolithic lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt, the Neolithic lasted until the Protodynastic period, 3150 BC.Karin Sowada and Peter Grave. Egypt in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arab Expansion
The spread of Islam spans about 1,400 years. Muslim conquests following Muhammad's death led to the creation of the caliphates, occupying a vast geographical area; conversion to Islam was boosted by Arab Muslim forces conquering vast territories and building imperial structures over time. Most of the significant expansion occurred during the reign of the Rashidun from 632 to 661 CE, which was the reign of the first four successors of Muhammad. These early caliphates, coupled with Islamic economics in the world, Muslim economics and trading, the Islamic Golden Age, and the age of the Islamic gunpowder empires, resulted in Islam's spread outwards from Mecca towards the Indian Ocean, Indian, Atlantic Ocean, Atlantic, and Pacific Ocean, Pacific Oceans and the creation of the Muslim world. Trade played an important role in the spread of Islam in several parts of the world, especially Islam in Indonesia, Indian traders in Southeast Asia.Berkey, pg. 101-102 Muslim dynasties were soon es ...

Taforalt
Taforalt or Grotte des Pigeons is a cave in the province of Berkane, Aït Iznasen region, Morocco, possibly the oldest cemetery in North Africa (Humphrey ''et al.'' 2012). It contained at least 34 Iberomaurusian adolescent and adult human skeletons, as well as younger ones, from the Upper Palaeolithic between 15,100 and 14,000 calendar years ago. There is archaeological evidence for Iberomaurusian occupation at the site between 23,200 and 12,600 calendar years ago, as well as evidence for Aterian occupation as old as 85,000 years. Site description La Grotte des Pigeons is a cave in eastern Morocco near the village of Taforalt. Human occupation and natural processes in the cave have produced a thick sequence of archaeological layers dating between at least 85,000 and 10,000 years ago. These occupation layers include pre-Mousterian, Aterian, and Iberomaurusian lithic industries, plus an unusual non-Levallois industry between the Aterian and the Iberomaurusian dating to c. 24,500 ...

Prehistory
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Northern Africa
North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritania in the west, to Egypt's Suez Canal. Varying sources limit it to the countries of Algeria, Libya, Morocco, and Tunisia, a region that was known by the French during colonial times as "''Afrique du Nord''" and is known by Arabs as the Maghreb ("West", ''The western part of Arab World''). The United Nations definition includes Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, and the Western Sahara, the territory disputed between Morocco and the Sahrawi Republic. The African Union definition includes the Western Sahara and Mauritania but not Sudan. When used in the term Middle East and North Africa (MENA), it often refers only to the countries of the Maghreb. North Africa includes the Spanish cities of Ceuta and Melilla, and plazas de soberanía ... [...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] |
East Africa
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.

Horn Of Africa
The Horn of Africa (HoA), also known as the Somali Peninsula, is a large peninsula and geopolitical region in East Africa.Robert Stock, ''Africa South of the Sahara, Second Edition: A Geographical Interpretation'', (The Guilford Press; 2004), p. 26 Located on the easternmost part of the African mainland, it is the fourth largest peninsula in the world. It is composed of Ethiopia, Eritrea, Somalia and Djibouti; broader definitions also include parts or all of Kenya, Sudan, South Sudan, and Uganda. The term Greater Horn Region (GHR) can additionally include Burundi, Rwanda, and Tanzania. It lies along the southern boundary of the Red Sea and extends hundreds of kilometres into the Guardafui Channel, Gulf of Aden, and Indian Ocean and shares a maritime border with the Arabian Peninsula of Western Asia. Names This peninsula has been known by various names. Ancient Greeks and Romans referred to it as Regio Aromatica or Regio Cinnamonifora due to the aromatic plants or as Regio I ...
