Timeline Of Human Prehistory
This timeline of prehistory covers the time from the first appearance of ''Homo sapiens'' in Africa 315,000 years ago to the invention of writing, over 4,000 years ago, with the earliest records going back to 3,200 BC. Prehistory covers the time from the Middle Paleolithic (Old Stone Age) to the very beginnings of ancient history. All dates are approximate and subject to revision based on new discoveries or analyses. Middle Paleolithic :''See Timeline of human evolution, Timeline of natural history for earlier evolutionary history.'' * ∼320,000 to 305,000 years ago: Populations at Olorgesailie in Southern Kenya undergo technological improvements in tool making and engage in long-distance trade. * 315,000 years ago: approximate date of appearance of ''Homo sapiens'' (Jebel Irhoud, Morocco). * 270,000 years ago: age of Y-DNA haplogroup A00 ("Y-chromosomal Adam"). * 250,000 years ago: first appearance of ''Homo neanderthalensis'' ( Saccopastore skulls). * 230,000–150,00 ...

Homo Sapiens
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically mod ...

Wadi Halfa
Wādī Ḥalfā ( ar, وادي حلفا) is a city in the Northern state of Sudan on the shores of Lake Nubia near the border with Egypt. It is the terminus of a rail line from Khartoum and the point where goods are transferred from rail to ferries going down the lake. As of 2007, the city had a population of 15,725. The city is located amidst numerous ancient Nubian antiquities and was the focus of much archaeological work by teams seeking to save artifacts from the flooding caused by the completion of the Aswan Dam. History Archaeological evidence indicates that settlement has been in the area since ancient times, and during the Middle Kingdom period, the Egyptian colony of Buhen across the river existed until the Roman period. The modern town of Wadi Halfa was founded in the 19th century, when it became a port on the Nile for steamers from Aswan, such as the ''Nubia''. During the Turko-Egyptian conquest of 1820, Wadi Halfa was used as a stopping point for troops headed so ...

Khoisanid
Khoisan , or (), according to the contemporary Khoekhoegowab orthography, is a catch-all term for those indigenous peoples of Southern Africa who do not speak one of the Bantu languages, combining the (formerly "Khoikhoi") and the or ( in the Nǁng language). The San were formerly called Bushmen, (from Afrikaans ''Boesmans'' from nl, Boschjesmens); and the were formerly known as " Hottentots", speculated to be a Dutch onomatopoeic term referring to the click consonants prevalent in the Khoekhoe languages. However there is no evidence of this etymology."A very large number of different etymologies for the name have been suggested ... The most frequently repeated suggestion ... is that the word was a spec. use of a formally identical Dutch word meaning ‘stammerer, stutterer’, which came to be applied to the Khoekhoe and San people on account of the clicks characteristic of their languages. However, evidence for the earlier general use appears to be lacking. Another f ...

Abbassia Pluvial
The Abbassia Pluvial was an extended wet and rainy period in the climate history of North Africa, lasting from c. 120,000 to 90,000 years ago. As such it spans the transitional period connecting the Lower and Middle Paleolithic. As with the subsequent Mousterian Pluvial (c. 50,000 to 30,000 years ago), the Abbassia Pluvial brought wet and fertile conditions to what is now the Sahara Desert, which bloomed with lush vegetation fed by lakes, swamps, and river systems, many of which later disappeared in the drier climate that followed the pluvial. African wildlife that is now associated with the grasslands and woodlands south of the Sahara penetrated the entire North African region during the Abbassia Pluvial. Stone Age cultures (notably the Mousterian and the Aterian industries) flourished in North Africa during the Abbassia Pluvial. The shift to harsher climate conditions that came with the end of the pluvial may have promoted the emigration of modern ''Homo sapiens'' out of Afr ...

Neandertals
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor ''H. heidelbergensis'' is also unclear. The oldest potential Neanderthal bones date to 430,000 years ago, but the classification r ...

Origin Of Language
The origin of language (spoken and signed, as well as language-related technological systems such as writing), its relationship with human evolution, and its consequences have been subjects of study for centuries. Scholars wishing to study the origins of language must draw inferences from evidence such as the fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition, and comparisons between human language and systems of communication existing among animals (particularly other primates). Many argue that the origins of language probably relate closely to the origins of modern human behavior, but there is little agreement about the facts and implications of this connection. The shortage of direct, empirical evidence has caused many scholars to regard the entire topic as unsuitable for serious study; in 1866, the Linguistic Society of Paris banned any existing or future debates on the subject, a prohibition which remained influen ...

Symbolic Culture
Symbolic culture, or nonmaterial culture, is the ability to learn and transmit behavioral traditions from one generation to the next by the invention of things that exist entirely in the symbolic realm. Symbolic culture is usually conceived as the cultural realm constructed and inhabited uniquely by ''Homo sapiens'' and is differentiated from ordinary culture, which many other animals possess. Symbolic culture is studied by archaeologists, social anthropologists and sociologists. From 2018, however, some evidence of a Neanderthal origin of symbolic culture emerged. Symbolic culture contrasts with material culture, which involves physical entities of cultural value and includes the usage, consumption, creation, and trade of objects. Examples of symbolic culture include concepts (such as good and evil), mythical inventions (such as gods and underworlds), and social constructs (such as promises and football games). Symbolic culture is a domain of objective facts whose existence depend ...

Eemian
The Eemian (also called the last interglacial, Sangamonian, Sangamonian Stage, Ipswichian, Mikulin, Kaydaky, penultimate,NOAA - Penultimate Interglacial Period http://www.ncdc.noaa.gov/global-warming/penultimate-interglacial-period Valdivia or Riss-Würm) was the interglacial period which began about 130,000 years ago at the end of the Penultimate Glacial Period and ended about 115,000 years ago at the beginning of the Last Glacial Period. It corresponds to Marine Isotope Stage 5e. Although sometimes referred to as the "last interglacial" (in the "most recent previous" sense of "last"), it was the second-to-latest interglacial period of the current Ice Age, the most recent being the Holocene which extends to the present day (having followed the last glacial period). The prevailing Eemian climate was, on average, around 1 to 2 degrees Celsius (1.8 to 3.6 Fahrenheit) warmer than that of the Holocene. During the Eemian, the proportion of in the atmosphere was about 280 parts per mill ...

Crete
Crete ( el, Κρήτη, translit=, Modern: , Ancient: ) is the largest and most populous of the Greek islands, the 88th largest island in the world and the fifth largest island in the Mediterranean Sea, after Sicily, Sardinia, Cyprus, and Corsica. Crete rests about south of the Greek mainland, and about southwest of Anatolia. Crete has an area of and a coastline of 1,046 km (650 mi). It bounds the southern border of the Aegean Sea, with the Sea of Crete (or North Cretan Sea) to the north and the Libyan Sea (or South Cretan Sea) to the south. Crete and a number of islands and islets that surround it constitute the Region of Crete ( el, Περιφέρεια Κρήτης, links=no), which is the southernmost of the 13 top-level administrative units of Greece, and the fifth most populous of Greece's regions. Its capital and largest city is Heraklion, on the north shore of the island. , the region had a population of 636,504. The Dodecanese are located to the no ...

Haplogroup L0 (mtDNA)
Haplogroup L0 is a human mitochondrial DNA (mtDNA) haplogroup. Origin L0 is one of two branches from the most recent common ancestor (MRCA) for the shared human maternal lineage. The haplogroup consists of five main branches (L0a, L0b, L0d, L0f, L0k). Four of them were originally classified into L1 subclades, L1a, L1d, L1f and L1k. In 2014, ancient DNA analysis of a 2,330 year old male forager's skeleton in Southern Africa found that the specimen belonged to the L0d2c1c mtDNA subclade. This maternal haplogroup is today most closely associated with the Ju, a subgroup of the indigenous San people, which points to population continuity in the region. In 2016, a Late Iron Age desiccated mummy from the Tuli region in northern Botswana was also found to belong to haplogroup L0. Distribution L0 is found most commonly in Sub-Saharan Africa. It reaches its highest frequency in the Khoisan people at 73% on average. Some of the highest frequencies are: Namibia ( !Xun) 79%, South Africa ...
