Homo Rhodesiensis
''Homo rhodesiensis'' is the species name proposed by Arthur Smith Woodward (1921) to classify Kabwe 1 (the "Kabwe skull" or "Broken Hill skull", also "Rhodesian Man"), a Middle Stone Age fossil recovered from a cave at Broken Hill, or Kabwe, Northern Rhodesia (now Zambia).. In 2020, the skull was dated to 324,000 to 274,000 years ago. Other similar older specimens also exist. ''Homo rhodesiensis'' s.s. appears to have diverged earlier than ''H. heidelbergensis'' s.s. (Mauer)''. H. rhodesiensis'' s.l. is now mostly considered a synonym of ''H. heidelbergensis'' s.l', or perhaps then slightly larger. Other designations such as ''Homo sapiens arcaicus'' and ''Homo sapiens rhodesiensis'' have also been proposed. Fossils A number of morphologically comparable fossil remains came to light in East Africa (Bodo, Ndutu, Eyasi, Ileret) and North Africa (Salé, Rabat, Dar-es-Soltane, Djbel Irhoud, Sidi Aberrahaman, Tighenif) during the 20th century. *Kabwe 1, also called the Broken ...

Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an age in the international geologic timescale or a stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.770 Ma (770,000 years ago) and 0.126 Ma (126,000 years ago), also expressed as 770–126 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian and succeeded by the proposed Tarantian. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. It ends with the onset of the Eemian interglacial period (Marine Isotope Stage 5). The term Middle Pleistocene was in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). W ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

List Of Hominina Fossils
The following tables give an overview of notable finds of hominin fossils and remains relating to human evolution, beginning with the formation of the tribe Hominini (the divergence of the human and chimpanzee lineages) in the late Miocene, roughly 7 to 8 million years ago. As there are thousands of fossils, mostly fragmentary, often consisting of single bones or isolated teeth with complete skulls and skeletons rare, this overview is not complete, but show some of the most important findings. The fossils are arranged by approximate age as determined by radiometric dating and/or incremental dating and the species name represents current consensus; if there is no clear scientific consensus the other possible classifications are indicated. The early fossils shown are not considered ancestors to ''Homo sapiens'' but are closely related to ancestors and are therefore important to the study of the lineage. After 1.5 million years ago (extinction of '' Paranthropus''), all fossils sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Fossil Sites
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues). Lagerstätten are indicated by a note () in the noteworthiness column. Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed. Such sites may have separate entries if they are considered to be more notable than the formation as a whole. In contrast, extensive formations associated with large areas m ...

Saldanha Man
__NOTOC__ Saldanha man also known as Saldanha cranium or Elandsfontein cranium are fossilized remains of an archaic human. It is one of the key specimens for ''Homo heidelbergensis''. It has not been dated directly, and is estimated to be roughly 0.5 million years old. The remains, which included a fragment of lower jaw, were found on an exposed surface between shifting sand dunes on the farm Elandsfontein, which is located near Hopefield, South Africa. It was found associated with a variety of fossil vertebrates, and initially classified as ''Homo saldanensis'' (Drennan 1955). Singer (1954) noted close resemblance to Kabwe 1 at Broken Hill (Zambia) and LH 18 at Laetoli (Tanzania). Comparison with Kabwe 1 specifically, and thus classification as African ''H. heidelbergensis'' (''H. rhodesiensis'') was also regularly supported by later authors.

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] |
Ndutu Cranium
The Ndutu skull is the partial cranium of a hominin that has been assigned variously to late '' Homo erectus'' ''Homo rhodesiensis'', and early ''Homo sapiens'', from the Middle Pleistocene, found at Lake Ndutu in northern Tanzania. Discovery Lake Ndutu is a seasonal soda lake in the Serengeti, adjacent to Lake Masek and the Main Gorge at Olduvai. During September and October 1973, Amini Aza Mturi and the Tanzanian Department of Antiquities conducted an excavation of the exposed flats of the western shoreline of Lake Ndutu. The excavation site was approximately in area and had considerable amounts of lithic and faunal material on the surface; the Ndutu cranium was found on the first occupational floor of the site. Amini Aza Mturi’s excavation found 270 lithic and faunal materials in the first occupational floor of the excavation site, of which 20 were definitive tools. The tools were mainly spheroids and hammerstones, with six flakes (three regular flakes, two triangular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Ergaster
''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 ''Homo erectus, H. erectus'' is an ongoing and unresolved dispute within paleoanthropology, palaeoanthropology. Proponents of synonymisation typically designate ''H. ergaster'' as "African ''Homo erectus''" or "''Homo erectus ergaster''". The name ''Homo ergaster'' roughly translates to ":wikt:ergaster, 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, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethiopia
Ethiopia, , om, Itiyoophiyaa, so, Itoobiya, ti, ኢትዮጵያ, Ítiyop'iya, aa, Itiyoppiya officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period.

Awash River
The Awash (sometimes spelled Awaash; Oromo: ''Awaash'', Amharic: አዋሽ, Afar: ''We'ayot'', Somali: ''Webiga Dir'') is a major river of Ethiopia. Its course is entirely contained within the boundaries of Ethiopia and empties into a chain of interconnected lakes that begin with Lake Gargori and end with Lake Abbe (or Abhe Bad) on the border with Djibouti, some 100 kilometres (60 or 70 miles) from the head of the Gulf of Tadjoura. It is the principal stream of an endorheic drainage basin covering parts of the Amhara, Oromia and Somali Regions, as well as the southern half of the Afar Region. The Awash Valley (and especially the Middle Awash) is internationally famous for its high density of hominin fossils, offering unparalleled insight into the early evolution of humans. "Lucy", one of the most famous early hominin fossils, was discovered in the lower Awash Valley. For its paleontological and anthropological importance, the lower valley of the Awash was inscribed on the UN ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bodo Cranium
''Homo bodoensis'' is the species name for extinct archaic humans that lived during the Chibanian (770–126 ka) in Africa. It relies on the fossil specimen known as Bodo cranium, which was discovered in 1976 from the Awash River in Ethiopia and is estimated to have lived around 500,000 years ago. Following the comparative analysis of the fossil with those of other ''Homo'' falling on the same geological age, the name was formally introduced in 2021. Based on the confusing usage of scientific names for different hominin specimens of the Chibanian, a research team led by Mirjana Roksandic at the University of Winnipeg, Canada, proposed in ''Evolutionary Anthropology'' that ''H. bodoensis'' should be used as an umbrella name for all species of the same age in Africa, including ''H. rhodesiensis'' and ''H. heidelbergensis.'' But not all scientists agree. British paleoanthropologist Chris Stringer argued that the name cannot replace ''H. rhodesiensis'' to which Bodo cranium is ...
