Home Secretary Of Queensland
A home, or domicile, is a space used as a permanent or semi-permanent residence for one or many humans, and sometimes various companion animals. It is a fully or semi sheltered space and can have both interior and exterior aspects to it. Homes provide sheltered spaces, for instance rooms, where domestic activity can be performed such as sleeping, preparing food, eating and hygiene as well as providing spaces for work and leisure such as remote working, studying and playing. Physical forms of homes can be static such as a house or an apartment, mobile such as a houseboat, trailer or yurt or digital such as virtual space. The aspect of ‘home’ can be considered across scales; from the micro scale showcasing the most intimate spaces of the individual dwelling and direct surrounding area to the macro scale of the geographic area such as town, village, city, country or planet. The concept of ‘home’ has been researched and theorized across disciplines – topics ranging ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Tufa
Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine. It should not be confused with hot spring (thermogene) travertine. Tufa, which is calcareous, should also not be confused with tuff, a porous volcanic rock with a similar etymology that is sometimes also called "tufa". Classification and features Modern and fossil tufa deposits abound with wetland plants; as such, many tufa deposits are characterised by their large macrobiological component, and are highly porous. Tufa forms either in fluvial channels or in lacustrine environments. Ford and Pedley (1996) provide a review of tufa systems worldwide. Fluvial deposits Deposits can be classified by their depositional environment (or otherwise by vegetation or petrographically). Pedle ...

Wonderwerk Cave
Wonderwerk Cave is an archaeological site, formed originally as an ancient solution cavity in dolomite rocks of the Kuruman Hills, situated between Danielskuil and Kuruman in the Northern Cape Province, South Africa. It is a National Heritage Site, managed as a satellite of the McGregor Museum in Kimberley. Geologically, hillside erosion exposed the northern end of the cavity, which extends horizontally for about into the base of a hill. Accumulated deposits inside the cave, up to in-depth, reflect natural sedimentation processes such as water and wind deposition as well as the activities of animals, birds, and human ancestors over some 2 million years. The site has been studied and excavated by archaeologists since the 1940s and research here generates important insights into human history in the subcontinent of Southern Africa. Evidence within Wonderwerk cave has been called the oldest controlled fire. Wonderwerk means "miracle" in the Afrikaans language. Archaeological seq ...

Taung Child
The Taung Child (or Taung Baby) is the fossilised skull of a young ''Australopithecus africanus''. It was discovered in 1924 by quarrymen working for the Northern Lime Company in Taung, South Africa. Raymond Dart described it as a new species in the journal ''Nature'' in 1925. The Taung skull is in repository at the University of Witwatersrand. Dean Falk, a specialist in brain evolution, has called it "the most important anthropological fossil of the twentieth century." History Background In the early 20th century, the workers at limestone quarries in Southern Africa routinely uncovered fossils from the tufa formations that they mined. The tufa did not form consistently, and over time cavities were left open and they became beneficial areas for animals to take shelter in. As a result, many bones began to build up in these areas. These areas were mostly sandstone, and they stood in the way of successful mining. So, miners would use explosives to clear these areas, and disca ...

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 ...

Australopithecus Sediba
''Australopithecus sediba'' is an extinct species of australopithecine recovered from Malapa Cave, Cradle of Humankind, South Africa. It is known from a partial juvenile skeleton, the holotype MH1, and a partial adult female skeleton, the paratype MH2. They date to about 1.98 million years ago in the Early Pleistocene, and coexisted with ''Paranthropus robustus'' and ''Homo ergaster'' / ''Homo erectus''. Malapa is interpreted as having been a natural death trap, the base of a long vertical shaft which creatures could accidentally fall into. ''A. sediba'' was initially described as being a potential human ancestor, and perhaps the progenitor of ''Homo'', but this is contested and it could also represent a late-surviving population or sister species of '' A. africanus'' which had earlier inhabited the area. MH1 has a brain volume of about 420–440 cc, similar to other australopithecines. The face of MH1 is strikingly similar to ''Homo'' instead of other australopithecines, with ...

Australopithecus Africanus
''Australopithecus africanus'' is an extinct species of australopithecine which lived between about 3.3 and 2.1 million years ago in the Late Pliocene to Early Pleistocene of South Africa. The species has been recovered from Taung, Sterkfontein, Makapansgat, and Gladysvale. The first specimen, the Taung child, was described by anatomist Raymond Dart in 1924, and was the first early hominin found. However, its closer relations to humans than to other apes would not become widely accepted until the middle of the century because most had believed humans evolved outside of Africa. It is unclear how ''A. africanus'' relates to other hominins, being variously placed as ancestral to ''Homo'' and '' Paranthropus'', to just ''Paranthropus'', or to just '' P. robustus''. The specimen "Little Foot" is the most completely preserved early hominin, with 90% of the skeleton intact, and the oldest South African australopith. However, it is controversially suggested that it and similar speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malapa
Malapa is a fossil-bearing cave located about northeast of the well known South African hominid-bearing sites of Sterkfontein and Swartkrans and about north-northwest of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site. History of investigations In March 2008, Lee Berger of the University of the Witwatersrand, South Africa, undertook an exploration project in the Cradle of Humankind World Heritage site outside of Johannesburg, in order to map the known caves identified by him and his colleagues over the past several decades, and to place known fossil sites onto Google Earth so that information could be shared with colleagues. The area is important as nearly a third of the entire evidence for human origins in Africa comes from just a few sites in this region, and the region is arguably one of the most explored areas in Africa for evidence of human origins, having been investigated continuously since the first discoveries were ma ...

Drimolen
The Drimolen Palaeocave System consists of a series of terminal Pliocene to early Pleistocene hominin-bearing palaeocave fills located around north of Johannesburg, South Africa, and about north of Sterkfontein in the UNESCO World Heritage Site Cradle of Humankind. History of Research The site was discovered on 9 July 1992 by Andre Keyser and he continued to direct excavations at the site until his death in 2010. *On 21 October 1994, Keyser discovered the DNH 7 (Eurydice) skull, the most complete ''Paranthropus robustus'' skull found. It is also considered a rare female skull of ''P. robustus''. DNH 8, a male mandible called "Orpheus" was also discovered at the same time and adjacent to DNH 7. Colin Menter directed research and excavations at the site from 2010 until 2016. Excavations at the site were conducted by technical assistants in the early years and by a number of field schools in the latter years. These include the University of Florence, Italy (2006-2012), the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kromdraai
Kromdraai Conservancy is a protected conservation park located to the south-west of Gauteng province in north-east South Africa. It is in the Muldersdrift area not far from Krugersdorp. Etymology Its name is derived from Afrikaans meaning "Crooked Turn" after a kink in the meandering Crocodile River. History It was established to protect the caves, old gold mines, fossil sites, trout farm and a game reserve in the area. The caves in the area, known as the Sterkfontein caves have an extensive number of fossils and dolomite caverns. A well known fossil site is also named Kromdraai and it, along with such sites as Sterkfontein, Coopers, Swartkrans and Plovers Lake form part of the conservancy. Part of the Kromdraai conservancy also falls within the Cradle of Humankind World Heritage Site, proclaimed by UNESCO in 1998.
