Middle Stone Age
The Middle Stone Age (or MSA) was a period of African prehistory between the Early Stone Age and the Late Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago. The beginnings of particular MSA stone tools have their origins as far back as 550–500,000 years ago and as such some researchers consider this to be the beginnings of the MSA. The MSA is often mistakenly understood to be synonymous with the Middle Paleolithic of Europe, especially due to their roughly contemporaneous time span; however, the Middle Paleolithic of Europe represents an entirely different hominin population, Neanderthal, ''Homo neanderthalensis'', than the MSA of Africa, which did not have Neanderthal populations. Additionally, current archaeological research in Africa has yielded much evidence to suggest that modern human behavior and cognition was beginning to develop much earlier in Africa during the MSA than it was in Europe during the M ...

Paleolithic
The Paleolithic or Palaeolithic ( years ago) ( ), 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 Hominini, hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 Before Present#Radiocarbon calibration, cal Before Present, BP. The Paleolithic Age in Europe preceded the Mesolithic Age, although the date of the transition varies geographically by several thousand years. During the Paleolithic Age, hominins grouped together in small societies such as band society, bands and subsisted by gathering plants, fishing, and hunting or scavenging wild animals. The Paleolithic Age is characterized by the use of Knapping, knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for ...

Human Variability
Human variability, or human variation, is the range of possible values for any characteristic, human biology, physical or psychology, mental, of human, human beings. Frequently debated areas of variability include cognitive ability, personality, Human physical appearance, physical appearance (body shape, skin color, etc.) and immunology. Variability is partly heritability, heritable and partly Environment (biophysical), acquired (''nature vs. nurture'' debate). As the human species exhibits sexual dimorphism, many traits show significant variation not just between populations but also sex differences in humans, between the sexes. Sources of human variability Human variability is attributed to a combination of environmental and genetic sources including: For the genetic variables listed above, few of the traits characterizing human variability are controlled by simple Mendelian inheritance. Most are polygenic or are determined by a complex combination of genetics and envir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaic Admixture To Anatomically Modern Humans
Interbreeding between archaic and modern humans occurred during the Middle Paleolithic and early Upper Paleolithic. The interbreeding happened in several independent events that included Neanderthals and Denisovans, as well as several unidentified hominins. In Europe, Asia and North Africa, interbreeding between archaic humans and modern humans took place several times. The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans. Neanderthal-derived DNA has been found in the genomes of most contemporary populations, varying noticeably by region. It accounts for 1–4% of modern genomes for people outside Sub-Saharan Africa, although estimates vary, and either none or up to 0.3% for those in Sub-Saharan Africa. Cushitic and Semitic speaking populations from the Horn of Africa (such as Ethiopians), who derive a large portion of their ancestry from West Eurasians, ...

Archaic Human
''Homo'' () is a genus of great ape (family Hominidae) that emerged from the genus ''Australopithecus'' and encompasses only a single extant species, ''Homo sapiens'' (modern humans), along with a number of extinct species (collectively called archaic humans) 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 (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. ''H. erectus'' appeared about 2 million years ago and spread throughout Africa (deba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makapansgat
Makapansgat () (or Makapan Valley World Heritage Site) is an archaeological location within the Makapansgat and Zwartkrans Valleys, northeast of Mokopane in Limpopo province, South Africa. It is an important palaeontological site, with the local Lime (material), limeworks containing ''Australopithecus''-bearing deposits dating to between 3.0 and 2.6 million years Before Present, BP. The whole Makapan Valley has been declared a National heritage sites (South Africa), South African Heritage Site. Makapansgat belongs to the Cradle of Humankind. Makapansgat Valley sites Makapansgat limeworks This is the oldest of the cave sites in the Makapansgat valley, spanning an age of greater than 4.0 million years until perhaps 1.6 million years ago. This site has yielded many thousands of fossil bones, amongst which were found remains of the gracile australopithecine ''Australopithecus africanus''. The ''A. africanus'' fossils are suggested to date to between 2.85 and 2.58 million years ago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bouri Formation
The Bouri Formation is a sequence of sedimentary deposits that is the source of australopithecine and Homo (that is, hominin) fossils, Artifact (archaeology), 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, Ethiopia, Gona and Hadar, Ethiopia, Hadar. The Bouri Formation stretches down much of the length and breadth of the Bouri "peninsula", which projects across the dry bed of the Afar Depression. The Formation is sufficiently eroded to expose three geological members or layers: the Hatayae, the Dakanihylo, and the Herto. Human remains with signs of having been prepared for burial have been found in the Upper Herto layers. Geology The Bouri "peninsula" is a geological Fault (geology), fault-raised Horst (geology), horst that diverts the Awash River, forming a partial dam ...

Middle Awash
The Middle Awash is a paleoanthropological research area in the northwest corner of Gabi Rasu in the Afar Region along the Awash River in Ethiopia's Afar Depression. It is a unique natural laboratory for the study of human origins and evolution and a number of fossils of the earliest hominins, particularly of the ''Australopithecines'', as well as some of the oldest known Olduwan stone artifacts, have been found at the site—all of late Miocene, the Pliocene, and the very early Pleistocene times, that is, about 5.6 million years ago (mya) to 2.5 mya. It is broadly thought that the divergence of the lines of the earliest humans (hominins) and of chimpanzees (hominids) was completed near the beginning of that time range, or sometime between seven and five mya. However, the larger community of scientists provide several estimates for periods of divergence that imply a greater range for this event, ''see'' CHLCA: human-chimpanzee split.

Levallois Technique
The Levallois technique () is a name given by archaeologists to a distinctive type of stone knapping developed around 250,000 to 400,000Shipton, C. (2022). Predetermined Refinement: The Earliest Levallois of the Kapthurin Formation. *Journal of Paleolithic Archaeology*, 5, 4. https://doi.org/10.1007/s41982-021-00109-1 years ago during the Middle Palaeolithic period. It is part of the Mousterian stone tool industry, and was used by the Neanderthals in Europe and by modern humans in other regions such as the Levant. It is named after 19th-century finds of flint tools in the Levallois-Perret suburb of Paris, France. The technique was more sophisticated than earlier methods of lithic reduction, involving the striking of lithic flakes from a prepared lithic core. A striking platform is formed at one end and then the core's edges are trimmed by flaking off pieces around the outline of the intended lithic flake. This creates a domed shape on the side of the core, known as a tortoise c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomically Modern Humans
Early modern human (EMH), or anatomically modern human (AMH), are terms used to distinguish ''Homo sapiens'' ( sometimes ''Homo sapiens sapiens'') that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species (of which some are at times also identified with, but only one, prefix ''sapiens''). 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 founded 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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauresmith Industry
In archaeology, Fauresmith industry is a stone tool industry that is transitional between the Acheulian and the Middle Stone Age. It is at the end of the Acheulian or beginning of the Middle Stone Age. It is named after the town of Fauresmith in South Africa. The Fauresmith is found at a number of other archaeological sites such as Wonderwerk Cave and Kathu Pan where it is potentially dated to at least 420,000 years ago. The Fauresmith consists of Middle Stone Age technology such as blades, points and prepared core technology as well as retaining handaxes from the Acheulian. The type sites are Brakfontein 321 and Riverview Estates Site VI. The Fauresmith culture shows Levalloisean influence, with hand-axes and flakes with faceted striking platforms. It is largely in the similar period with the Sangoan __TOC__ The Sangoan is a prehistoric lithic industry of sub-Saharan Africa, broadly dated to the later part of the Early Stone Age (ESA) and the transition to the Middle Ston ...
