Early Stone Age
The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age. It spans the time from around 3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries. In African archaeology, the time period roughly corresponds to the Early Stone Age, the earliest finds dating back to 3.3 million years ago, with Lomekwian stone tool technology, spanning Mode 1 stone tool technology, which begins roughly 2.6 million years ago and ends between 400,000 and 250,000 years ago, with Mode 2 technology. The Middle Paleolithic followed the Lower Paleolithic and recorded the appearance of the more advanced prepared-core tool-making technologies such as the Mousterian. Whether the earliest control of fire by hominins dates to the Lower or to the Middle Paleolithic remains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australopithecine
Australopithecina or Hominina is a subtribe in the tribe Hominini. The members of the subtribe are generally ''Australopithecus'' (cladistically including the genus, genera ''Homo'', ''Paranthropus'', and ''Kenyanthropus''), and it typically includes the earlier ''Ardipithecus'', ''Orrorin'', ''Sahelanthropus'', and ''Graecopithecus''. All these closely related species are now sometimes collectively termed australopiths or homininians. They are the extinct, close relatives of humans and, with the extant genus ''Homo'', comprise the human clade. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are now called Hominina (''see Hominidae; Hominidae#Terminology, terms "hominids" and hominins''). While none of the groups normally directly assigned to this group survived, the australopiths do not appear to be literally extinct (in the sense of having no living descendants) as the genera ''Kenyanthropus'', ''Paranthropus'' and ''Homo'' probably emerged ...

Biomechanics
Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. Biomechanics is a branch of biophysics. In 2022, computational mechanics goes far beyond pure mechanics, and involves other physical actions: chemistry, heat and mass transfer, electric and magnetic stimuli and many others. Etymology The word "biomechanics" (1899) and the related "biomechanical" (1856) come from the Ancient Greek βίος ''bios'' "life" and μηχανική, ''mēchanikē'' "mechanics", to refer to the study of the mechanical principles of living organisms, particularly their movement and structure. Subfields Biofluid mechanics Biological fluid mechanics, or biofluid mechanics, is the study of both gas and liquid fluid flows in or around biological organisms. An often studied liquid biofluid problem is that of blood flow in the human card ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaîne Opératoire
Chaîne opératoire (; ) is a term used throughout anthropological discourse, but is most commonly used in archaeology and sociocultural anthropology. It functions as a methodological tool for analysing the technical processes and social acts involved in the step-by-step production, use, and eventual disposal of artifacts, such as lithic reduction (the making of stone tools) or pottery. This concept of technology as the science of human activities was first proposed by French archaeologist, André Leroi-Gourhan, and later by the historian of science André-Georges Haudricourt. Both were students of Marcel Mauss who had earlier recognised that societies could be understood through its techniques by virtue of the fact that operational sequences are steps organised according to an internal logic specific to a society. The chaîne opératoire was born out of the need to explicitly describe the methodology of lithic analysis in archaeological scholarship. It allows archaeologists to ...

Homo Erectus
''Homo erectus'' (; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Several human species, such as '' H. heidelbergensis'' and '' H. antecessor'' — with the former generally considered to have been the ancestor to Neanderthals, Denisovans, and modern humans — appear to have evolved from ''H. erectus''. Its specimens are among the first recognizable members of the genus ''Homo''. ''H. erectus'' was the first human ancestor to spread throughout Eurasia, with a continental range extending from the Iberian Peninsula to Java. Asian populations of ''H. erectus'' may be ancestral to '' H. floresiensis'' and possibly to '' H. luzonensis''. The last known population of ''H. erectus'' is '' H. e. soloensis'' from Java, around 117,000–108,000 years ago. ''H. erectus'' had a more modern gait and body proportions, and was the first human species to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acheulean
Acheulean (; also Acheulian and Mode II), 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''. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, East Asia and Europe, and are typically found with ''Homo erectus'' remains. It is thought that Acheulean technologies first developed about 1.76 million years ago, derived from the more primitive Oldowan technology associated with '' Homo habilis''. The Acheulean includes at least the early part of the Middle Paleolithic. Its end is not well defined, depending on whether Sangoan (also known as "Epi-Acheulean") is included, it may be taken to last until as late as 130,000 years ago. In Europe and Western Asia, early Neanderthals adopted Acheulean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Turkana
Lake Turkana (), formerly known as Lake Rudolf, is a lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. It is the world's largest permanent desert lake and the world's largest alkaline lake. By volume it is the world's fourth-largest salt lake after the Caspian Sea, Issyk-Kul, and Lake Van (passing the shrinking South Aral Sea), and among all lakes it ranks 24th. Lake Turkana is now threatened by the construction of Gilgel Gibe III Dam in Ethiopia due to the damming of the Omo river which supplies most of the lake's water. Although the lake commonly has been —and to some degree still is— used for drinking water, its salinity (slightly brackish) and very high levels of fluoride (much higher than in fluoridated water) generally make it unsuitable, and it has also been a source of diseases spread by contaminated water. Increasingly, communities on the lake's shores rely on underground springs for drinking water. The same c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paranthropus Robustus
''Paranthropus robustus'' is a species of robustness (morphology), robust australopithecine from the Early Pleistocene, Early and possibly Middle Pleistocene, Middle Pleistocene of the Cradle of Humankind, South Africa, about 2.27 to 0.87 (or, more conservatively, 2 to 1) million years ago. It has been identified in Kromdraai, Swartkrans, Sterkfontein, Gondolin Cave, Gondolin, Cooper's Cave, Cooper's, and Drimolen Caves. Discovered in 1938, it was among the first early hominins described, and became the type species for the genus ''Paranthropus''. However, it has been argued by some that ''Paranthropus'' is an invalid grouping and synonym (taxonomy), synonymous with ''Australopithecus'', so the species is also often classified as ''Australopithecus robustus''. Robust australopithecines—as opposed to gracility, gracile australopithecines—are characterised by heavily built skulls capable of producing high stress (physics), stresses and bite forces, as well as inflated cheek teet ...

Paranthropus Aethiopicus
''Paranthropus aethiopicus'' is an extinct species of robust australopithecine from the Late Pliocene to Early Pleistocene of East Africa about 2.7–2.3 million years ago. However, it is much debated whether or not ''Paranthropus'' is an invalid grouping and is synonymous with ''Australopithecus'', so the species is also often classified as ''Australopithecus aethiopicus''. Whatever the case, it is considered to have been the ancestor of the much more robust '' P. boisei''. It is debated if ''P. aethiopicus'' should be subsumed under ''P. boisei'', and the terms ''P. boisei'' sensu lato ("in the broad sense") and ''P. boisei'' sensu stricto ("in the strict sense") can be used to respectively include and exclude ''P. aethiopicus'' from ''P. boisei''. Like other ''Paranthropus'', ''P. aethiopicus'' had a tall face, thick palate, and especially enlarged cheek teeth. However, likely due to its archaicness, it also diverges from other ''Paranthropus'', with some aspects resembling th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
