Homo sapiens in the context of Scientific names

Early modern human, or anatomically modern human, are terms used to distinguish Homo sapiens (the only extant Hominina species) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species. This distinction is useful especially for times and regions where anatomically modern and archaic humans co-existed, for example, in Paleolithic Europe. Among the oldest known remains of Homo sapiens are those found at the Omo-Kibish I archaeological site in south-western Ethiopia, dating to about 233,000 to 196,000 years ago, the Florisbad Skull found at the Florisbad archaeological and paleontological site in South Africa, dating to about 259,000 years ago, and the Jebel Irhoud site in Morocco, dated about 315,000 years ago.

Extinct species of the genus Homo include Homo erectus (extant from roughly 2,000,000 to 100,000 years ago) and a number of other species (by some authors considered subspecies of either H. sapiens or H. erectus). The divergence of the lineage leading to H. sapiens out of ancestral H. erectus (or an intermediate species such as Homo antecessor) is estimated to have occurred in Africa roughly 500,000 years ago. The earliest fossil evidence of early modern humans appears in Africa around 300,000 years ago, with the earliest genetic splits among modern people, according to some evidence, dating to around the same time. Sustained archaic human admixture with modern humans is known to have taken place both in Africa and (following the recent Out-Of-Africa expansion) in Eurasia, between about 100,000 and 30,000 years ago.

Homo (from Latin homō 'human') is a genus of great ape (family Hominidae) that emerged from the early homininian genus Australopithecus, encompassing a single extant species, Homo sapiens (modern humans), along with a number of extinct species (e.g. Homo erectus and Homo neanderthalensis) classified as either ancestral or closely related to modern humans, collectively called archaic humans. Homo, together with the genus Paranthropus, is probably most closely related to the species Australopithecus africanus within Australopithecus. The closest living relatives of Homo are of the hominin genus Pan (chimpanzees and bonobos), with the ancestors of Pan and Homo estimated to have diverged around 5.7–11 million years ago during the Late Miocene.

The oldest member of the genus is Homo habilis, with fossil records of just over 2 million years ago. H. erectus appeared about 2 million years ago and spread throughout Africa (debatably as another species called Homo ergaster) and Eurasia in several migrations. The species was adaptive and successful, and persisted for more than a million years before gradually diverging into new species around 500,000 years ago.

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 theory 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.

The history of Pakistan preceding the country's independence in 1947 is shared with that of Afghanistan, India, and Iran. Spanning the western expanse of the Indian subcontinent and the eastern borderlands of the Iranian plateau, the region of present-day Pakistan served both as the fertile ground of a major civilization and as the gateway of South Asia to Central Asia and the Near East.

Situated on the first coastal migration route of Homo sapiens out of Africa, the region was inhabited early by modern humans. The 9,000-year history of village life in South Asia traces back to the Neolithic (7000–4300 BCE) site of Mehrgarh in Pakistan, and the 5,000-year history of urban life in South Asia to the various sites of the Indus Valley Civilization, including Mohenjo Daro and Harappa.

Archaic humans emerged out of Africa between 0.5 and 1.8 million years ago. This was followed by the emergence of modern humans (Homo sapiens) in East Africa around 300,000–250,000 years ago. In the 4th millennium BC written history arose in Ancient Egypt, and later in Nubia's Kush, the Horn of Africa's Dʿmt, and Ifrikiya's Carthage. Between around 3000 BCE and 500 CE, the Bantu expansion swept from north-western Central Africa (modern day Cameroon) across much of Central, Eastern, and Southern Africa, displacing or absorbing groups such as the Khoisan and Pygmies. The oral word is revered in most African cultures, and history has generally been passed down through oral tradition. This has led anthropologists to term them "oral civilisations".

There were many kingdoms and empires all over the continent that rose and fell. Most states were created through conquest or the borrowing and assimilation of ideas and institutions, while others developed largely in isolation. Some African empires and kingdoms include:

The Levantine corridor is the relatively narrow strip in Western Asia, between the Mediterranean Sea to the northwest and deserts to the southeast, which connects Africa to Eurasia. It is the western part of the Fertile Crescent, the eastern part of the latter being Mesopotamia. This corridor is a land route of migrations of animals between Eurasia and Africa. In particular, it is believed that early hominins spread from Africa to Eurasia via the Levantine corridor and Horn of Africa. The corridor is named after the Levant.

In the history of art, prehistoric art is all art produced in preliterate, prehistorical cultures beginning somewhere in very late geological history, and generally continuing until that culture either develops writing or other methods of record-keeping, or makes significant contact with another culture that has, and that makes some record of major historical events. At this point ancient art begins, for the older literate cultures. The end-date for what is covered by the term thus varies greatly between different parts of the world.

The earliest human artifacts showing evidence of workmanship with an artistic purpose are the subject of some debate. It is clear that such workmanship existed 40,000 years ago in the Upper Paleolithic era, although it is quite possible that it began earlier. In September 2018, scientists reported the discovery of the earliest known drawing by Homo sapiens, which is estimated to be 73,000 years old, much earlier than the 43,000 years old artifacts understood to be the earliest known modern human drawings found previously.

Biological anthropology, also known as physical anthropology, is a natural science discipline concerned with the biological and behavioral aspects of human beings, their extinct hominin ancestors, and related non-human primates, particularly from an evolutionary perspective. This subfield of anthropology systematically studies human beings from a biological perspective.

Jebel Irhoud or Adrar n Ighoud (Standard Moroccan Tamazight: ⴰⴷⵔⴰⵔ ⵏ ⵉⵖⵓⴷ, romanized: Adrar n Iɣud; Arabic: جبل إيغود, Moroccan Arabic: žbəl iġud), is an archaeological site located just north of the town of Tlet Ighoud in Youssoufia Province, approximately 50 km (30 mi) south-east of the city of Safi in Morocco.

It is noted for the hominin fossils that have been found there since the discovery of the site in 1961. Originally thought to be Neanderthals, the specimens have since been assigned to Homo sapiens and, as reported in 2017, have been dated to roughly 300,000 years ago. This makes the remains by far the earliest known examples of Homo sapiens, and suggests that rather than arising in East Africa approximately 200,000 years ago, modern humans have been present across the length of Africa 100,000 years earlier.

Paleolithic Europe, or Old Stone Age Europe, encompasses the Paleolithic or Old Stone Age in Europe from the arrival of the first archaic humans, about 1.4 million years ago until the beginning of the Mesolithic (also Epipaleolithic) around 10,000 years ago. This period thus covers over 99% of the total human presence on the European continent. The early arrival and disappearance of Homo erectus and Homo heidelbergensis, the appearance, complete evolution and eventual demise of Homo neanderthalensis and the immigration and successful settlement of Homo sapiens all have taken place during the European Paleolithic.

The Florisbad Skull is an important human fossil of the early Middle Stone Age, representing either late Homo heidelbergensis or early Homo sapiens. It was discovered in 1932 by T. F. Dreyer at the Florisbad site, Free State Province, South Africa.

Human taxonomy is the classification of the human species within zoological taxonomy. The systematic genus, Homo, is designed to include both anatomically modern humans and extinct varieties of archaic humans. Current humans are classified as subspecies to Homo sapiens, differentiated, according to some, from the direct ancestor, Homo sapiens idaltu (with some other research instead classifying idaltu and current humans as belonging to the same subspecies).

Since the introduction of systematic names in the 18th century, knowledge of human evolution has increased significantly, and a number of intermediate taxa have been proposed in the 20th and early 21st centuries. The most widely accepted taxonomy grouping takes the genus Homo as originating between two and three million years ago, divided into at least two species, archaic Homo erectus and modern Homo sapiens, with about a dozen further suggestions for species without universal recognition.

Sangiran is an archaeological excavation site in Java in Indonesia. According to a UNESCO report (1995) "Sangiran is recognized by scientists to be one of the most important sites in the world for studying fossil man, ranking alongside Zhoukoudian (China), Willandra Lakes (Australia), Olduvai Gorge (Tanzania), and Sterkfontein (South Africa), and more fruitful in finds than any of these."

The area comprises about 56 km (7 km x 8 km). It is located in Central Java, about 15 kilometers north of Surakarta in the Solo River valley. Administratively, Sangiran area is divided between 2 regencies: Sragen (districts of Gemolong, Kalijambe, and Plupuh) and Karanganyar (district of Gondangrejo). An important feature of the site is the geology of the area. Originally a dome was created millions of years ago through tectonic uplifts. The dome was then eroded exposing beds within the dome which are rich in archeological records.

The first part of the name – the generic name – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus Homo and within this genus to the species Homo sapiens. Tyrannosaurus rex is likely the most widely known binomial. The formal introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work Species Plantarum in 1753. But as early as 1622, Gaspard Bauhin introduced in his book Pinax theatri botanici (English, Illustrated exposition of plants) containing many names of genera that were later adopted by Linnaeus. Binomial nomenclature was introduced in order to provide succinct, relatively stable and verifiable names that could be used and understood internationally, unlike common names which are usually different in every language.

In biological taxonomy, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as Homo sapiens or Bufo bufo) have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, family, order, class, phylum, kingdom, and domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and the Code for Viruses) require them. However, absolute ranks are not required in all nomenclatural systems for taxonomists; for instance, the PhyloCode, the code of phylogenetic nomenclature, does not require absolute ranks.

Taxa are hierarchical groups of organisms, and their ranks describes their position in this hierarchy. High-ranking taxa (e.g. those considered to be domains or kingdoms, for instance) include more sub-taxa than low-ranking taxa (e.g. those considered genera, species or subspecies). The rank of these taxa reflects inheritance of traits or molecular features from common ancestors. The name of any species and genus are basic; which means that to identify a particular organism, it is usually not necessary to specify names at ranks other than these first two, within a set of taxa covered by a given rank-based code. However, this is not true globally because most rank-based codes are independent from each other, so there are many inter-code homonyms (the same name used for different organisms, often for an animal and for a taxon covered by the botanical code). For this reason, attempts were made at creating a BioCode that would regulate all taxon names, but this attempt has so far failed because of firmly entrenched traditions in each community.
