Paleolithic
–
It extends from the earliest known use of stone tools, probably by Homo habilis initially,2.6 million years ago, to the end of the Pleistocene around 10,000 BP. The Paleolithic era is followed by the Mesolithic, the date of the Paleolithic–Mesolithic boundary may vary by locality as much as several thousand years. During the Paleolithic period, humans grouped together in small societies such as bands, the Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers, however, due to their nature, surviving artifacts of the Paleolithic era are known as paleoliths. About 50,000 years ago, there was a increase in the diversity of artifacts. For the first time in Africa, bone artifacts and the first art appear in the archaeological record, the first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa. The new technology generated an explosion of modern humans which is believed to have led to the extinction of the Neanderthals. Humankind gradually evolved from members of the genus Homo—such as Homo habilis. The climate during the Paleolithic consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures, by c. 50,000 – c. 40,000 BP, the first humans set foot in Australia. By c. 45,000 BP, humans lived at 61°N latitude in Europe, by c. 30,000 BP, Japan was reached, and by c. 27,000 BP humans were present in Siberia, above the Arctic Circle. At the end of the Upper Paleolithic, a group of humans crossed Beringia, the term Paleolithic was coined by archaeologist John Lubbock in 1865. It derives from Greek, παλαιός, palaios, old, and λίθος, lithos, stone, human evolution is the part of biological evolution concerning the emergence of anatomically modern humans as a distinct species. The Paleolithic Period coincides almost exactly with the Pleistocene epoch of geologic time and this epoch experienced important geographic and climatic changes that affected human societies. During the preceding Pliocene, continents had continued to drift from possibly as far as 250 km from their present locations to positions only 70 km from their current location. South America became linked to North America through the Isthmus of Panama, most of Central America formed during the Pliocene to connect the continents of North and South America, allowing fauna from these continents to leave their native habitats and colonize new areas. Africas collision with Asia created the Mediterranean Sea, cutting off the remnants of the Tethys Ocean, climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. The formation of an Arctic ice cap around 3 million years ago is signaled by a shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic. Mid-latitude glaciation probably began before the end of the epoch, the global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas
2.
Oldowan
–
The Oldowan, sometimes spelled Olduwan, is the earliest widespread stone tool archaeological industry in prehistory. Oldowan tools were used during the Lower Paleolithic period,2.6 million years ago up until 1.7 million years ago, by ancient hominids across much of Africa, South Asia and this technological industry was followed by the more sophisticated Acheulean industry. The term Oldowan is taken from the site of Olduvai Gorge in Tanzania, classification of Oldowan tools is still somewhat contentious. Mary Leakey was the first to create a system to classify Oldowan assemblages, the system included choppers, scrapers, and pounders. However, more recent classifications of Oldowan assemblages have been made that focus primarily on manufacture due to the nature of assuming use from stone artefacts. An example is Isaac et al. s tri-modal categories of Flaked Pieces, Detached Pieces, Pounded Pieces, Oldowan tools are sometimes called pebble tools, so named because the blanks chosen for their production already resemble, in pebble form, the final product. It is not known for sure which hominin species actually created and used Oldowan tools and its emergence is often associated with the species Australopithecus garhi and its flourishing with early species of Homo such as H. habilis and H. ergaster. Early Homo erectus appears to inherit Oldowan technology and refines it into the Acheulean industry beginning 1.7 million years ago, the oldest known Oldowan tools have been found in Gona, Ethiopia, and are dated to about 2.6 mya. The use of tools by apes including chimpanzees and orangutans can be used to argue in favour of tool-use as a feature of the hominin family. Tools made from bone, wood, or other materials were therefore in all probability used before the Oldowan. Oldowan stone tools are simply the oldest recognisable tools which have preserved in the archaeological record. There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, at 1.7 mya. the first Acheulean tools appear even as Oldowan assemblages continue to be produced. Both technologies are found in the same areas, dating to the same time periods. This realisation required a rethinking of old cultural sequences in which the more advanced Acheulean was supposed to have succeeded the Oldowan. Sometime before 1.8 mya Homo erectus had spread outside of Africa, reaching as far east as Java by 1.8 mya, in these newly colonised areas, no Acheulean assemblages have been found. In China, only Mode 1 Oldowan assemblages were produced, while in Indonesia stone tools from this age are unknown, by 1.8 mya early Homo was present in Europe, as shown by the discovery of fossil remains and Oldowan tools in Dmanisi, Georgia. Remains of their activities have also excavated in Spain at sites in the Guadix-Baza basin. Most early European sites yield Mode 1 or Oldowan assemblages, the earliest Acheulean sites in Europe only appear around 0.5 mya

Acheulean
–
Acheulean, from the French acheuléen, is an archaeological industry of stone tool manufacture characterized by distinctive oval and pear-shaped hand-axes associated with early humans. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, and Europe, and are typically found with Homo erectus remains. It is thought that Acheulean technologies first developed in Africa out of the more primitive Oldowan technology as long ago as 1.76 million years ago, Acheulean tools were the dominant technology for the vast majority of human history. The type site for the Acheulean is Saint-Acheul, a suburb of Amiens, the capital of the Somme department in Picardy, john Frere is generally credited as being the first to suggest a very ancient date for Acheulean hand-axes. In 1797, he sent two examples to the Royal Academy in London from Hoxne in Suffolk and his ideas were, however, ignored by his contemporaries, who subscribed to a pre-Darwinian view of human evolution. Following visits to both Abbeville and Saint Acheul by the geologist Joseph Prestwich, the age of the tools was finally accepted, in 1872, Louis Laurent Gabriel de Mortillet described the characteristic hand-axe tools as belonging to LEpoque de St Acheul. The industry was renamed as the Acheulean in 1925, from the Konso Formation of Ethiopia, Acheulean hand-axes are dated to about 1.5 million years ago using radiometric dating of deposits containing volcanic ashes. Acheulean tools in South Asia have also found to be dated as far as 1.5 million years ago. However, the earliest accepted examples of the Acheulean currently known come from the West Turkana region of Kenya and were first described by a French-led archaeology team. These particular Acheulean tools were dated through the method of magnetostratigraphy to about 1.76 million years ago, making them the oldest not only in Africa. The earliest user of Acheulean tools was Homo ergaster, who first appeared about 1.8 million years ago, not all researchers use this formal name, and instead prefer to call these users early Homo erectus. In individual regions, this dating can be refined, in Europe for example. However more recent research demonstrated that hand-axes from Spain were made more than 900,000 years ago, the enormous geographic spread of Acheulean techniques also makes the name unwieldy as it represents numerous regional variations on a similar theme. The term Acheulean does not represent a culture in the modern sense. The very earliest Acheulean assemblages often contain numerous Oldowan-style flakes and core forms and these industries are known as the Developed Oldowan and are almost certainly transitional between the Oldowan and Acheulean. The Mode 1 industries created rough flake tools by hitting a stone with a hammerstone. The resulting flake that broke off would have a sharp edge for cutting. These early toolmakers may also have worked the stone they took the flake from to create chopper cores although there is debate over whether these items were tools or just discarded cores
4.
Mousterian
–
Mousterian is a name given by archaeologists to a style of predominantly flint tools associated primarily with Neanderthals. They date to the Middle Paleolithic, the part of the European Old Stone Age. The culture was named after the site of Le Moustier. Similar flintwork has been all over unglaciated Europe and also the Near East. Handaxes, racloirs and points constitute the industry, sometimes a Levallois technique or another prepared-core technique was employed in making the flint flakes, Mousterian tools that have been found in Europe were made by Neanderthals and date from around 160,000 BP and 40,000 BP. In North Africa and the Near East, Mouseterian tools were produced by anatomically modern humans. In the Levant, for example, assemblages produced by Neanderthals are indistinguishable from those made by Qafzeh type modern humans, possible variants are Denticulate, Charentian named after the Charente region, Typical and the Acheulean Tradition - Type-A and Type-B. The industry continued alongside the new Châtelperronian industry during the 45, Mousterian artifacts have been found in Haua Fteah in Cyrenaica and other sites in Northwest Africa. Contained within a cave in the Syria region, along with a Neanderthaloid skeleton, located in the Haibak valley of Afghanistan. Zagros and Central Iran The archaeological site of Atapuerca, Spain, gorhams Cave in Gibraltar contains Mousterian objects. Uzbekistan has sites of Mousterian culture, including Teshik-Tash, siberia has many sites with Mousterian style implements, eg Denisova Cave.

Upper Paleolithic
–
The Upper Paleolithic is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 10,000 years ago, roughly coinciding with the appearance of behavioral modernity, modern humans are believed to have emerged about 195,000 years ago in Africa. Although these humans were modern in anatomy, their lifestyle changed very little from their contemporaries, such as Homo erectus, about 50,000 years ago, there was a marked increase in the diversity of artifacts. In Africa, bone artifacts and the first art appear in the archeological record, between 45,000 and 43,000 years ago, this new tool technology spread with human migration to Europe. The new technology generated an explosion of modern humans which is believed to have contributed to the extinction of the Neanderthals. The Upper Paleolithic has the earliest known evidence of organized settlements, in the form of campsites, artistic work blossomed, with cave painting, petroglyphs, carvings and engravings on bone or ivory. The first evidence of fishing is also noted, from artifacts in places such as Blombos cave in South Africa. More complex social groupings emerged, supported by more varied and reliable food sources and this probably contributed to increasing group identification or ethnicity. By 50, 000–40,000 BP, the first humans set foot in Australia, by 45,000 BP, humans lived at 61° north latitude in Europe. By 30,000 BP, Japan was reached, and by 27,000 BP humans were present in Siberia above the Arctic Circle, at the end of the Upper Paleolithic, a group of humans crossed the Bering land bridge and quickly expanded throughout North and South America. Both Homo erectus and Neanderthals used the same crude stone tools, archaeologist Richard G. Klein, who has worked extensively on ancient stone tools, describes the stone tool kit of archaic hominids as impossible to categorize. It was as if the Neanderthals made stone tools, and were not much concerned about their final forms and he argues that almost everywhere, whether Asia, Africa or Europe, before 50,000 years ago all the stone tools are much alike and unsophisticated. These new stone-tool types have been described as being distinctly differentiated from each other, the invaders, commonly referred to as the Cro-Magnons, left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler, cave paintings and Venus figurines. The Neanderthals continued to use Mousterian stone tool technology and possibly Chatelperronian technology and these tools disappeared from the archeological record at around the same time the Neanderthals themselves disappeared from the fossil record, about 40,000 years ago. Settlements were often located in valley bottoms, possibly associated with hunting of passing herds of animals. Hunting was important, and caribou/wild reindeer may well be the species of single greatest importance in the anthropological literature on hunting. Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes, burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in period, along with the fish hook, the oil lamp, rope
6.
Aurignacian
–
The Aurignacian culture is an archaeological culture of the Upper Palaeolithic. It is the earliest modern human culture in Europe, and is associated with the immigration of anatomically modern humans from the Near East and it first appeared in Eastern Europe around 43,000 BP, and in Western Europe between 40,000 and 36,000 years BP. It was replaced by the Gravettian culture around 28,000 to 26,000 years ago, the name originates from the type site of Aurignac, Haute-Garonne, which is a town in the south-west of France near Toulouse or Andorra. The oldest undisputed example of figurative art, the Venus of Hohle Fels. It was discovered in September 2008 in a cave at Schelklingen in Baden-Württemberg in southern Germany, the Bacho Kiro site is one of the earliest known Aurignacian burials. The Aurignacian tool industry is characterized by worked bone or antler points with grooves cut in the bottom. Their flint tools include blades and bladelets struck from prepared cores rather than using crude flakes. )The people of this culture also produced some of the earliest known cave art, such as the animal engravings at Trois Freres. They also made pendants, bracelets, and ivory beads, as well as three-dimensional figurines, perforated rods, thought to be spear throwers or shaft wrenches, also are found at their sites. The sophistication and self-awareness demonstrated in the work led archaeologists to consider the makers of Aurignacian artifacts the first modern humans in Europe, human remains and Late Aurignacian artifacts found in juxtaposition support this inference. Although finds of human remains in direct association with Proto-Aurignacian technologies are scarce in Europe. At least three robust, but typically anatomically-modern individuals from the Peștera cu Oase cave in Romania, were dated directly from the bones to ca, although not associated directly with archaeological material, these finds are within the chronological and geographical range of the Early Aurignacian in southeastern Europe. On genetic evidence it has argued that both Aurignacian and the Dabba culture of North Africa came from an earlier big game hunting Aurignacian culture of the Levant. Many 35, 000-year-old animal figurines were discovered in the Vogelherd Cave in Germany, one of the horses, amongst six tiny mammoth and horse ivory figures found previously at Vogelherd, was sculpted as skillfully as any piece found throughout the Upper Paleolithic. The production of ivory beads for body ornamentation was also important during the Aurignacian, there is a notable absence of painted caves, however, which begin to appear within the Solutrean. Typical statuettes consist of women that are called Venus figurines and they emphasize the hips, breasts, and other body parts associated with fertility. Feet and arms are lacking or minimized, one of the most ancient figurines was discovered in 2008 in the Hohle Fels cave in Germany. The figurine has been dated to 35,000 years ago, the oldest undisputed musical instrument was the Hohle Fels Flute discovered in the Hohle Fels cave in Germanys Swabian Alb in 2008. The flute is made from a wing bone perforated with five finger holes

Hominini
–
Members of the human clade, that is, the Hominina, including Homo and those species of the australopithecines that arose after the split from the chimpanzees, are called homininans. Not all homininans are directly related to the emergence of early Homo and this is a modern cladogram, For each clade, the cladogram above shows approximately when newer extant clades emerged. Some texts refer to Homonini as the Hominina branch, the subtribe Hominina is the human branch, that is, it contains only the genus Homo. Researchers proposed the taxon Hominini on the basis that the least similar species of a trichotomy should be separated from the other two. The common chimpanzee and the bonobo of the genus Pan are the closest living relatives to humans. All the extinct genera listed to the right are ancestral to, or offshoots of, however, both Orrorin and Sahelanthropus existed around the time of the split, and so may be ancestral to both Pan and Homo. In the proposal of Mann and Weiss, the tribe Hominini includes Pan as well as Homo, Homo and all bipedal apes are referred to the subtribe Hominina, while Pan is assigned to the subtribe Panina. Wood discusses the different views of this taxonomy, the assumption of late hybridization was in particular based on the similarity of the X chromosome in humans and chimpanzees, suggesting a divergence as late as some 4 million years ago. Sahelanthropus tchadensis is an extinct species that lived seven million years ago. Human Timeline – Smithsonian, National Museum of Natural History

Pliocene
–
The Pliocene Epoch is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era, the Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch.588 to 1.806 million years ago, and is now included in the Pleistocene. As with other geologic periods, the geological strata that define the start and end are well identified but the exact dates of the start. The boundaries defining the Pliocene are not set at an easily identified worldwide event, the upper boundary was set at the start of the Pleistocene glaciations. The Pliocene was named by Sir Charles Lyell, the name comes from the Greek words πλεῖον and καινός and means roughly continuation of the recent, referring to the essentially modern marine mollusc faunas. H. W. Fowler called the term a regrettable barbarism, in the official timescale of the ICS, the Pliocene is subdivided into two stages. From youngest to oldest they are, Piacenzian Zanclean The Piacenzian is sometimes referred to as the Late Pliocene, in the system of North American Land Mammal Ages include Hemphillian, and Blancan. The Blancan extends forward into the Pleistocene, South American Land Mammal Ages include Montehermosan, Chapadmalalan and Uquian. In the Paratethys area the Pliocene contains the Dacian and Romanian stages, as usual in stratigraphy, there are many other regional and local subdivisions in use. In Britain the Pliocene is divided into the stages, Gedgravian, Waltonian, Pre-Ludhamian, Ludhamian, Thurnian, Bramertonian or Antian, Pre-Pastonian or Baventian, Pastonian and Beestonian. The exact correlations between these stages and the ICS stages is still a matter of detail. The formation of an Arctic ice cap is signaled by a shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic. Mid-latitude glaciation was probably underway before the end of the epoch, the global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas. Continents continued to drift, moving from positions possibly as far as 250 km from their present locations to positions only 70 km from their current locations, africas collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. The border between the Miocene and the Pliocene is also the time of the Messinian salinity crisis, Sea level changes exposed the land-bridge between Alaska and Asia. Pliocene marine rocks are exposed in the Mediterranean, India. Elsewhere, they are exposed largely near shores, the change to a cooler, dry, seasonal climate had considerable impacts on Pliocene vegetation, reducing tropical species worldwide. Deciduous forests proliferated, coniferous forests and tundra covered much of the north, tropical forests were limited to a tight band around the equator, and in addition to dry savannahs, deserts appeared in Asia and Africa

Natufian culture
–
The Epipaleolithic Natufian culture /nəˈtuːfiən/ existed from around 12,500 to 9,500 BC in the Levant, a region in the Eastern Mediterranean. It was unusual in that it supported a sedentary or semi-sedentary population even before the introduction of agriculture, the Natufian communities may be the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world. Natufians founded Jericho which may be the oldest city in the world, some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture, at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. Generally, though, Natufians exploited wild cereals, Dorothy Garrod coined the term Natufian based on her excavations at Shuqba cave in Wadi an-Natuf, in the western Judean Mountains. The Natufian culture was discovered by British archaeologist Dorothy Garrod during her excavations of Shuqba cave in the Judaean Hills, prior to the 1930s, the majority of archaeological work taking place in Palestine was biblical archaeology focused on historic periods, and little was known about the regions prehistory. She discovered a layer sandwiched between the Upper Palaeolithic and Bronze Age deposits characterised by the presence of microliths. She identified this with the Mesolithic, a period between the Palaeolithic and the Neolithic which was well represented in Europe but had not yet been found in the Near East. A year later, when she discovered similar material at el-Wad Terrace, Garrod suggested the name the Natufian culture, as early as 1931, both Garrod and Neuville drew attention to the presence of stone sickles in Natufian assemblages and the possibility that this represented very early agriculture. Radiocarbon dating places this culture from the terminal Pleistocene to the beginning of the Holocene. The period is split into two subperiods, Early Natufian and Late Natufian. The Late Natufian most likely occurred in tandem with the Younger Dryas, the Natufian developed in the same region as the earlier Kebaran industry. It is generally seen as a successor, which evolved out of elements within that preceding culture, more generally there has been discussion of the similarities of these cultures with those found in coastal North Africa. In fact, Weiss et al. have shown that the earliest known usage of plants was in the Levant 23,000 years ago at the Ohalo II site. Loring Brace cross-analysed the craniometric traits of Natufian specimens with those of ancient and modern groups from the Near East, Africa. Settlements occur in the belt where oak and Pistacia species dominated. The underbrush of this woodland was grass with high frequencies of grain. The habitations of the Natufian are semi-subterranean, often with a dry-stone foundation, the superstructure was probably made of brushwood. No traces of mudbrick have been found, which became common in the following Pre-Pottery Neolithic A, the round houses have a diameter between three and six meters, and they contain a central round or subrectangular fireplace

Stone Age
–
The Stone Age was a broad prehistoric period during which stone was widely used to make implements with an edge, a point, or a percussion surface. The period lasted roughly 3.4 million years, and ended between 8700 BCE and 2000 BCE with the advent of metalworking, bone tools were used during this period as well but are rarely preserved in the archaeological record. The Stone Age is further subdivided by the types of tools in use. According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia, where it is bordered by grasslands. The closest relative among the living primates, the genus Pan, represents a branch that continued on in the deep forest. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia. The oldest indirect evidence found of stone tool use is fossilised animal bones with tool marks, the oldest stone tools were excavated from the site of Lomekwi 3 in West Turkana, northwestern Kenya, and date to 3.3 million years old. Prior to the discovery of these Lomekwian tools, the oldest known stone tools had been found at sites at Gona, Ethiopia, on the sediments of the paleo-Awash River. All the tools come from the Busidama Formation, which lies above a disconformity, or missing layer, the oldest sites containing tools are dated to 2. 6–2.55 mya. One of the most striking circumstances about these sites is that they are from the Late Pliocene, excavators at the locality point out that. the earliest stone tool makers were skilled flintknappers. The possible reasons behind this seeming abrupt transition from the absence of tools to the presence thereof include. The species who made the Pliocene tools remains unknown, fragments of Australopithecus garhi, Australopithecus aethiopicus and Homo, possibly Homo habilis, have been found in sites near the age of the Gona tools. Innovation of the technique of smelting ore ended the Stone Age, the first most significant metal manufactured was bronze, an alloy of copper and tin, each of which was smelted separately. The Chalcolithic by convention is the period of the Bronze Age. The Bronze Age was followed by the Iron Age, the transition out of the Stone Age occurred between 6000 BCE and 2500 BCE for much of humanity living in North Africa and Eurasia. Note the Rudna Glava mine in Serbia, Ötzi the Iceman, a mummy from about 3300 BCE carried with him a copper axe and a flint knife. In regions such as Sub-Saharan Africa, the Stone Age was followed directly by the Iron Age, the Middle East and southeastern Asian regions progressed past Stone Age technology around 6000 BCE. Europe, and the rest of Asia became post–Stone Age societies by about 4000 BCE, the proto-Inca cultures of South America continued at a Stone Age level until around 2000 BCE, when gold, copper and silver made their entrance

Stone tool
–
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, archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a research field in order to further the understanding and cultural implications of stone tool use. Stone has been used to make a variety of different tools throughout history, including arrow heads, spearpoints. Stone tools may be made of ground stone or chipped stone. Chipped stone tools are made from materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt. One simple form of reduction is to strike stone flakes from a nucleus of material using a hammerstone or similar hard hammer fabricator, if the goal of the reduction strategy is to produce flakes, the remnant lithic core may be discarded once it has become too small to use. In some strategies, however, a flintknapper reduces the core to a rough unifacial or bifacial preform, more complex forms of reduction include the production of highly standardized blades, which can then be fashioned into a variety of tools such as scrapers, knives, sickles and microliths. Archaeologists classify stone tools into industries that share distinctive technological or morphological characteristics and he assigned to them relative dates, Modes 1 and 2 to the Lower Palaeolithic,3 to the Middle Palaeolithic,4 to the Advanced and 5 to the Mesolithic. They were not to be conceived, however, as either universal—that is, they did not account for all lithic technology, Mode 1, for example, was in use in Europe long after it had been replaced by Mode 2 in Africa. Clarkes scheme was adopted enthusiastically by the archaeological community, one of its advantages was the simplicity of terminology, for example, the Mode 1 / Mode 2 Transition. The transitions are currently of greatest interest, Kenya Stone tools found from 2011 to 2014 at Lake Turkana in Kenya, are dated to be 3.3 million years old, and predate the genus Homo by half million years. The oldest known Homo fossil is 2.8 million years old compared to the 3.3 million year old stone tools. Dating of the tools was by dating volcanic ash layers in which the tools were found, Oldowan tools were characterised by their simple construction, predominantly using core forms. The blunt end is the surface, the sharp, the distal. Grasping the proximal surface, the hominid brought the surface down hard on an object he wished to detach or shatter. The earliest known Oldowan tools yet found date from 2.6 million years ago, during the Lower Palaeolithic period, and have been uncovered at Gona in Ethiopia. Homo habilis was the hominin who used the tools for most of the Oldowan in Africa, eventually, more complex, Mode 2 tools began to be developed through the Acheulean Industry, named after the site of Saint-Acheul in France

Solutrean
–
The Solutrean industry is a relatively advanced flint tool-making style of the Upper Palaeolithic, from around 22,000 to 17,000 BP. The term Solutrean comes from the type-site of Cros du Charnier, dating to around 21,000 years ago and located at Solutré, the Rock of Solutré site was discovered in 1866 by the French geologist and paleontologist Henry Testot-Ferry. It is now preserved as the Parc archéologique et botanique de Solutré, the eras finds include tools, ornamental beads, and bone pins as well as prehistoric art. Solutrean tool-making employed techniques not seen before and not rediscovered for millennia, the Solutrean has relatively finely worked, bifacial points made with lithic reduction percussion and pressure flaking rather than cruder flintknapping. Knapping was done using antler batons, hardwood batons and soft stone hammers and this method permitted the working of delicate slivers of flint to make light projectiles and even elaborate barbed and tanged arrowheads. Bone and antler were used as well, the Solutrean may be seen as a transitory stage between the flint implements of the Mousterian and the bone implements of the Magdalenian epochs. Faunal finds include horse, reindeer, mammoth, cave lion, rhinoceros, bear, Solutrean finds have been also made in the caves of Les Eyzies and Laugerie Haute, and in the Lower Beds of Creswell Crags in Derbyshire, England. The industry first appeared in what is now Spain, and disappears from the record around 17,000 BP. The migrants arrived in northeastern North America and served as the culture for what eventually developed into Clovis tool-making technology. The idea of a Clovis-Solutrean link remains controversial and does not enjoy wide acceptance, in 2014, the autosomal DNA of a male infant from a 12, 500-year-old deposit in Montana was sequenced. The DNA was taken from a referred to as Anzick-1. The skeleton was found in association with several Clovis artifacts. Comparisons showed strong affinities with DNA from Siberian sites, and virtually ruled out any close affinity of Anzick-1 with European sources, Clovis and Solutrean, Is There a Common Thread. by James M
