Historical Migration
:'' This article focusses on prehistorical migration since the Neolithic period until AD 1800. See Early human migrations for migration prior to the Neolithic, History of human migration for modern history, and human migration for contemporary migration.'' Paleolithic migration prior to end of the Last Glacial Maximum spread anatomically modern humans throughout Afro-Eurasia and to the Americas. During the Holocene climatic optimum, formerly isolated populations began to move and merge, giving rise to the pre-modern distribution of the world's major language families. In the wake of the population movements of the Mesolithic came the Neolithic revolution, followed by the Indo-European expansion in Eurasia and the Bantu expansion in Africa. Population movements of the proto-historical or early historical period include the Migration period, followed by (or connected to) the Slavic, Magyar, Norse, Turkic and Mongol expansions of the medieval period.

Early Human Migrations
Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents. They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by '' Homo erectus''. This initial migration was followed by other archaic humans including '' H. heidelbergensis'', which lived around 500,000 years ago and was the likely ancestor of Denisovans and Neanderthals as well as modern humans. Early hominids had likely crossed land bridges that have now sunk. Within Africa, '' Homo sapiens'' dispersed around the time of its speciation, roughly 300,000 years ago. The recent African origin paradigm suggests that the anatomically modern humans outside of Africa descend from a population of ''Homo sapiens'' migrating from East Africa roughly 70–50,000 years ago and spreading along the southern coast of Asia and to Oceania by about 50,000 years ago. Modern humans spread across Europe about 40,000 years ago. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongol Invasions
The Mongol invasions and conquests took place during the 13th and 14th centuries, creating history's largest contiguous empire: the Mongol Empire ( 1206- 1368), which by 1300 covered large parts of Eurasia. Historians regard the Mongol devastation as one of the deadliest episodes in history. In addition, Mongol expeditions may have spread the bubonic plague across much of Eurasia, helping to spark the Black Death of the 14th century. The Mongol Empire developed in the course of the 13th century through a series of victorious campaigns throughout Asia, reaching Eastern Europe by the 1240s. In contrast with later "empires of the sea" such as European colonial powers, the Mongol Empire was a land power, fueled by the grass-foraging Mongol cavalry and cattle. Thus most Mongol conquest and plundering took place during the warmer seasons, when there was sufficient grazing for their herds. The rise of the Mongols was preceded by 15 years of wet and warm weather conditions from 1211 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hunter-gatherer
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local sources, especially edible wild plants but also insects, fungi, honey, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish), roughly as most animal omnivores do. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups in ...

Mesolithic
The Mesolithic (Greek: μέσος, ''mesos'' 'middle' + λίθος, ''lithos'' 'stone') or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and Western Asia, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in Southwest Asia (the Epipalaeolithic Near East) roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa. The type of culture associated with the Mesolithic varies between areas, but it is associated with a decline in the group hunting of large animals in favour of a broader hunter-g ...

Archaeogenetics
Archaeogenetics is the study of ancient DNA using various molecular genetic methods and DNA resources. This form of genetic analysis can be applied to human, animal, and plant specimens. Ancient DNA can be extracted from various fossilized specimens including bones, eggshells, and artificially preserved tissues in human and animal specimens. In plants, Ancient DNA can be extracted from seeds and tissue. Archaeogenetics provides us with genetic evidence of ancient population group migrations, domestication events, and plant and animal evolution. The ancient DNA cross referenced with the DNA of relative modern genetic populations allows researchers to run comparison studies that provide a more complete analysis when ancient DNA is compromised. Archaeogenetics receives its name from the Greek word ''arkhaios'', meaning "ancient", and the term ''genetics'', meaning "the study of heredity". The term archaeogenetics was conceived by archaeologist Colin Renfrew. In February 2021, scienti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fertile Crescent
The Fertile Crescent ( ar, الهلال الخصيب) is a crescent-shaped region in the Middle East, spanning modern-day Iraq, Syria, Lebanon, Israel, Palestine and Jordan, together with the northern region of Kuwait, southeastern region of Turkey and the western portion of Iran. Some authors also include Cyprus and Northern Egypt. The Fertile Crescent is believed to be the very first region where settled farming emerged as people started the process of clearance and modification of natural vegetation to grow newly domesticated plants as crops. Early human civilizations such as Sumer in Mesopotamia flourished as a result. Technological advances in the region include the development of agriculture and the use of irrigation, of writing, the wheel, and glass, most emerging first in Mesopotamia. Terminology The term "Fertile Crescent" was popularized by archaeologist James Henry Breasted in ''Outlines of European History'' (1914) and ''Ancient Times, A History of the Early W ...

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colonial Empires
A colonial empire is a collective of territories (often called colonies), either contiguous with the imperial center or located overseas, settled by the population of a certain state and governed by that state. Before the expansion of early modern European powers, other empires had conquered and colonized territories, such as the Roman Empire in Iberia, or the Chinese in what is now southern China. Modern colonial empires first emerged with a race of exploration between the then most advanced European maritime powers, Portugal and Spain, during the 15th century. The initial impulse behind these dispersed maritime empires and those that followed was trade, driven by the new ideas and the capitalism that grew out of the European Renaissance. Agreements were also made to divide the world up between them in 1479, 1493, and 1494. European imperialism was born out of competition between European Christians and Ottoman Muslims, the latter of which rose up quickly in the 14th century a ...
