The Paleolithic or Palaeolithic, also called the Old Stone Age, is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by hominins, c. 3.3 million years ago, to the end of the Pleistocene, c. 11,650 cal BP.
The Stone Age was a broad prehistoric period during which stone was widely used to make stone tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years and ended between 4,000 BC and 2,000 BC, with the advent of metalworking. It therefore represents nearly 99.3% of human history. Though some simple metalworking of malleable metals, particularly the use of gold and copper for purposes of ornamentation, was known in the Stone Age, it is the melting and smelting of copper that marks the end of the Stone Age. In Western Asia, this occurred by about 3,000 BC, when bronze became widespread. The term Bronze Age is used to describe the period that followed the Stone Age, as well as to describe cultures that had developed techniques and technologies for working copper alloys into tools, supplanting stone in many uses.
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture.
Homo ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene. Whether H. ergaster constitutes a species of its own or should be subsumed into H. erectus is an ongoing and unresolved dispute within palaeoanthropology. Proponents of synonymisation typically designate H. ergaster as "African Homo erectus" or "Homo erectus ergaster". The name Homo ergaster roughly translates to "working man", a reference to the more advanced tools used by the species in comparison to those of their ancestors. The fossil range of H. ergaster mainly covers the period of 1.7 to 1.4 million years ago, though a broader time range is possible. Though fossils are known from across East and Southern Africa, most H. ergaster fossils have been found along the shores of Lake Turkana in Kenya. There are later African fossils, some younger than 1 million years ago, that indicate long-term anatomical continuity, though it is unclear if they can be formally regarded as H. ergaster specimens. As a chronospecies, H. ergaster may have persisted to as late as 600,000 years ago, when new lineages of Homo arose in Africa.
The Olduvai Gorge or Oldupai Gorge in Tanzania is one of the most important paleoanthropological localities in the world; the many sites exposed by the gorge have proven invaluable in furthering understanding of early human evolution. A steep-sided ravine in the Great Rift Valley that stretches across East Africa, it is about 48 km long, and is located in the eastern Serengeti Plains within the Ngorongoro Conservation Area in the Olbalbal ward located in Ngorongoro District of Arusha Region, about 45 kilometres from Laetoli, another important archaeological locality of early human occupation. The British/Kenyan paleoanthropologist-archeologist team of Mary and Louis Leakey established excavation and research programs at Olduvai Gorge that achieved great advances in human knowledge and are world-renowned. The site is registered as one of the National Historic Sites of Tanzania.
Homo heidelbergensis is an extinct species or subspecies of archaic human which existed during the Middle Pleistocene. It was subsumed as a subspecies of H. erectus in 1950 as H. e. heidelbergensis, but towards the end of the century, it was more widely classified as its own species. It is debated whether or not to constrain H. heidelbergensis to only Europe or to also include African and Asian specimens, and this is further confounded by the type specimen being a jawbone, because jawbones feature few diagnostic traits and are generally missing among Middle Pleistocene specimens. Thus, it is debated if some of these specimens could be split off into their own species or a subspecies of H. erectus. Because the classification is so disputed, the Middle Pleistocene is often called the "muddle in the middle".
Acheulean, from the French acheuléen after the type site of Saint-Acheul, is an archaeological industry of stone tool manufacture characterized by the distinctive oval and pear-shaped "hand axes" associated with Homo erectus and derived species such as Homo heidelbergensis.
The Oldowan was a widespread stone tool archaeological industry (style) in prehistory. These early tools were simple, usually made with one or a few flakes chipped off with another stone. Oldowan tools were used during the Lower Paleolithic period, 2.9 million years ago up until at least 1.7 million years ago (Ma), by ancient Hominins across much of Africa. This technological industry was followed by the more sophisticated Acheulean industry.
Homo is a genus of great ape that emerged from the genus Australopithecus and encompasses the extant species Homo sapiens and a number of extinct species classified as either ancestral or closely related to modern humans. These include Homo erectus and Homo neanderthalensis. The oldest member of the genus is Homo habilis, with records of just over 2 million years ago. 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 genus Pan, with the ancestors of Pan and Homo estimated to have diverged around 5.7-11 million years ago during the Late Miocene.
Africa has the longest record of human habitation in the world. The first hominins emerged 6–7 million years ago, and among the earliest anatomically modern human skulls found so far were discovered at Omo Kibish,Jebel Irhoud, and Florisbad.
The Middle Paleolithic is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia. The term Middle Stone Age is used as an equivalent or a synonym for the Middle Paleolithic in African archeology. The Middle Paleolithic broadly spanned from 300,000 to 50,000 years ago. There are considerable dating differences between regions. The Middle Paleolithic was succeeded by the Upper Paleolithic subdivision which first began between 50,000 and 40,000 years ago. Pettit and White date the Early Middle Paleolithic in Great Britain to about 325,000 to 180,000 years ago, and the Late Middle Paleolithic as about 60,000 to 35,000 years ago. The Middle Paleolithic was in the geological Chibanian and Late Pleistocene ages.
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 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.
Homo erectus is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Its specimens are among the first recognizable members of the genus Homo.
The Bouri Formation is a sequence of sedimentary deposits that is the source of australopithecine and Homo fossils, artifacts, and bones of large mammals with cut marks from butchery with tools by early hominins. It is located in the Middle Awash Valley, in Ethiopia, East Africa, and is a part of the Afar Depression that has provided rich human fossil sites such as Gona and Hadar.
Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they first used to hunt food, and later to cook.
Tautavel Man refers to the archaic humans which—from approximately 550,000 to 400,000 years ago—inhabited the Caune de l’Arago, a limestone cave in Tautavel, France. They are generally grouped as part of a long and highly variable lineage of transitional morphs which inhabited the Middle Pleistocene of Europe, and would eventually evolve into the Neanderthals. They have been variably assigned to either H. (s.?) heidelbergensis, or as a European subspecies of H. erectus as H. e. tautavelensis. The skull is reconstructed based on the specimens Arago 21 and 47, and it is, to a degree, more characteristic of what might be considered a typical H. erectus morphology than a typical H. heidelbergensis morphology. The brain capacity is 1,166 cc. They seem to have had an overall robust skeleton. Average height may have been 166 cm.
The following outline is provided as an overview of and topical guide to prehistoric technology.
Several expansions of populations of archaic humans out of Africa and throughout Eurasia took place in the course of the Lower Paleolithic, and into the beginning Middle Paleolithic, between about 2.1 million and 0.2 million years ago (Ma). These expansions are collectively known as Out of Africa I, in contrast to the expansion of Homo sapiens (anatomically modern humans) into Eurasia, which may have begun shortly after 0.2 million years ago.
The diet of known human ancestors varies dramatically over time. Strictly speaking, according to evolutionary anthropologists and archaeologists, there is not a single hominin Paleolithic diet. The Paleolithic covers roughly 2.8 million years, concurrent with the Pleistocene, and includes multiple human ancestors with their own evolutionary and technological adaptations living in a wide variety of environments. This fact with the difficulty of finding conclusive evidence often makes broad generalizations of the earlier human diets very difficult. Our pre-hominin primate ancestors were broadly herbivorous, relying on either foliage or fruits and nuts and the shift in dietary breadth during the Paleolithic is often considered a critical point in hominin evolution. A generalization between Paleolithic diets of the various human ancestors that many anthropologists do make is that they are all to one degree or another omnivorous and are inextricably linked with tool use and new technologies. Nonetheless, according to the California Academy of Sciences, "Prior to about 3.5 million years ago, early humans dined almost exclusively on leaves and fruits from trees, shrubs, and herbs—similar to modern-day gorillas and chimpanzees."
Gona is a paleoanthropological research area in Ethiopia's Afar Region. Gona is primarily known for its archaeological sites and discoveries of hominin fossils from the Late Miocene, Early Pliocene and Early Pleistocene. Fossils of Ardipithecus and Homo erectus were discovered there. Two of the most significant finds are an Ardipithecus ramidus postcranial skeleton and an essentially complete Homo erectus pelvis. Historically, Gona had the oldest documented Oldowan artifact assemblages. Archaeologists have since found older examples of the Oldowan at other sites. Still, Gona's Oldowan assemblages have been essential to the archaeological understanding of the Oldowan. Gona's Acheulean archaeological sites have helped us understand the beginnings of the Acheulean Industry.
