Prehistoric Tetrapod Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Proto-language
In the tree model of historical linguistics, a proto-language is a postulated ancestral language from which a number of attested languages are believed to have descended by evolution, forming a language family. Proto-languages are usually unattested, or partially attested at best. They are reconstructed by way of the comparative method. In the family tree metaphor, a proto-language can be called a mother language. Occasionally, the German term ' (; from 'primordial', 'original' + 'language') is used instead. It is also sometimes called the ''common'' or ''primitive'' form of a language (e.g. Common Germanic, Primitive Norse). In the strict sense, a proto-language is the most recent common ancestor of a language family, immediately before the family started to diverge into the attested ''daughter languages''. It is therefore equivalent with the ''ancestral language'' or ''parental language'' of a language family. Moreover, a group of lects that are not considered separate ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folklore
Folklore is the body of expressive culture shared by a particular group of people, culture or subculture. This includes oral traditions such as Narrative, tales, myths, legends, proverbs, Poetry, poems, jokes, and other oral traditions. This also includes material culture, such as traditional building styles common to the group. Folklore also encompasses customary lore, taking actions for folk beliefs, including folk religion, and the forms and rituals of celebrations such as Christmas, weddings, folk dances, and Rite of passage, initiation rites. Each one of these, either singly or in combination, is considered a Cultural artifact, folklore artifact or Cultural expressions, traditional cultural expression. Just as essential as the form, folklore also encompasses the transmission of these artifacts from one region to another or from one generation to the next. Folklore is not something one can typically gain from a formal school curriculum or study in the fine arts. Instead, thes ...

Anthropology
Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, society, societies, and linguistics, in both the present and past, including archaic humans. Social anthropology studies patterns of behaviour, while cultural anthropology studies cultural meaning, including norms and values. The term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological anthropology, Biological (or physical) anthropology studies the biology and evolution of Human evolution, humans and their close primate relatives. Archaeology, often referred to as the "anthropology of the past," explores human activity by examining physical remains. In North America and Asia, it is generally regarded as a branch of anthropology, whereas in Europe, it is considered either an independent discipline or classified under related fields like history and palaeontology.

Archaeology
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. The discipline involves Survey (archaeology), surveying, Archaeological excavation, excavation, and eventually Post excavation, analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. A ...

Protohistory
Protohistory is the period between prehistory and written history, during which a culture or civilization has not yet developed writing, but other cultures that have developed writing have noted the existence of those pre-literate groups in their own writings. Protohistoric may also refer to the transition period between the advent of literacy in a society and the writings of the first historians. The preservation of oral traditions may complicate matters, as they can provide a secondary historical source for even earlier events. Colonial sites involving a literate group and a nonliterate group are also studied as protohistoric situations. The term can also refer to a period in which fragmentary or external historical documents, not necessarily including a developed writing system, have been found. For instance, the Proto–Three Kingdoms of Korea, the Yayoi, recorded by the Chinese, and the Mississippian groups, recorded by early European explorers, are protohistoric. U ...

Prehistory Of Australia
The prehistory of Australia is the period between the first human habitation of the Australian continent and the colonisation of Australia in 1788, which marks the start of consistent written documentation of Australia. This period has been variously estimated, with most evidence suggesting that it goes back between 50,000 and 65,000 years. This era is referred to as prehistory rather than history because knowledge of this time period does not derive from written documentation. However, some argue that Indigenous oral tradition should be accorded an equal status. Human habitation of the Australian continent began with the migration of the ancestors of today's Aboriginal Australians by Land bridge, land bridges and short sea crossings from what is now Southeast Asia. It is uncertain how many waves of immigration may have contributed to these ancestors of modern Aboriginal Australians.Malaspinas, A. S., Westaway, M. C., Muller, C., Sousa, V.

Pre-Columbian Era
In the history of the Americas, the pre-Columbian era, also known as the pre-contact era, or as the pre-Cabraline era specifically in Brazil, spans from the initial peopling of the Americas in the Upper Paleolithic to the onset of European colonization of the Americas, European colonization, which began with Christopher Columbus's voyage in 1492. This era encompasses the history of Indigenous peoples of the Americas, Indigenous cultures prior to significant European influence, which in some cases did not occur until decades or even centuries after Columbus's arrival. During the pre-Columbian era, many civilizations developed permanent settlements, cities, agricultural practices, civic and monumental architecture, major Earthworks (archaeology), earthworks, and Complex society, complex societal hierarchies. Some of these civilizations had declined by the time of the establishment of the first permanent European colonies, around the late 16th to early 17th centuries, and are know ...

Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.''Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a single continent, the Americas or America is the 2nd largest continent by area after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their Lists of islands of the Americas, associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon basin, Amazon, St. Lawrence River–Great Lakes, Mississippi River System, Mississippi, and Río de la Plata Basin, La Plata basins.

Sub-Saharan Africa
Sub-Saharan Africa is the area and regions of the continent of Africa that lie south of the Sahara. These include Central Africa, East Africa, Southern Africa, and West Africa. Geopolitically, in addition to the list of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations geoscheme for Africa, United Nations (UN). This is considered a non-standardised geographical region with the number of countries included varying from 46 to 48 depending on the organisation describing the region (e.g. United Nations, UN, World Health Organization, WHO, World Bank, etc.). The Regions of the African Union, African Union (AU) uses a different regional breakdown, recognising all 55 member states on the continent—grouping them into five distinct and standard regions.
