African Wild Dog
The African wild dog (''Lycaon pictus''), also called the painted dog or Cape hunting dog, is a wild canine which is a native species to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus '' Lycaon'', which is distinguished from '' Canis'' by dentition highly specialised for a hypercarnivorous diet, and by a lack of dewclaws. It is estimated that about 6,600 adults (including 1,400 mature individuals) live in 39 subpopulations that are all threatened by habitat fragmentation, human persecution, and outbreaks of disease. As the largest subpopulation probably comprises fewer than 250 individuals, the African wild dog has been listed as endangered on the IUCN Red List since 1990. The species is a specialised diurnal hunter of antelopes, which it catches by chasing them to exhaustion. Its natural enemies are lions and spotted hyenas: the former will kill the dogs where possible, whilst hyenas are frequent kleptoparasites. Like ...

Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an Age (geology), age in the international geologic timescale or a Stage (stratigraphy), 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 annum, 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 Palaeolithic, Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian (stage), 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-fo ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xhosa Language
Xhosa (, ) also isiXhosa as an endonym, is a Nguni language and one of the official languages of South Africa and Zimbabwe. Xhosa is spoken as a first language by approximately 8.2 million people and by another 11 million as a second language in South Africa, mostly in Eastern Cape, Western Cape, Northern Cape and Gauteng. It has perhaps the heaviest functional load of click consonants in a Bantu language (approximately tied with Yeyi), with one count finding that 10% of basic vocabulary items contained a click. Classification Xhosa is part of the branch of Nguni languages, which also include Zulu, Southern Ndebele and Northern Ndebele. Nguni languages effectively form a dialect continuum of variously mutually intelligible varieties. Xhosa is, to some extent, mutually intelligible with Zulu and with other Nguni languages to a lesser extent. Nguni languages are, in turn, classified under the much larger abstraction of Bantu languages. Geographical dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zimbabwean Ndebele Language
Northern Ndebele (), also called Ndebele, isiNdebele saseNyakatho, Zimbabwean Ndebele or North Ndebele, associated with the term Matabele, is a Bantu language spoken by the Northern Ndebele people which belongs to the Nguni group of languages. As a start and to give some context, Ndebele is a term used to refer to a collection of many different African cultures in Zimbabwe. It perhaps by default became a 'language' (for lack of better word) spoken predominantly by the descendants of Mzilikazi. As a language, it is by no means similar to the Ndebele language spoken in kwaNdebele in South Africa although, like many Nguni dialects, some words will be shared. Many of the natives that were colonized by the Matabele were assimilated into Mzilikazi's kingdom to create a version of isiZulu. The Matebele people of Zimbabwe descend from followers of the Zulu leader Mzilikazi (one of Zulu King Shaka's generals), who left the Zulu Kingdom in the early 19th century, during the Mfecane ...

Damara Language
The Khoekhoe language (), also known by the ethnic terms Nama (''Namagowab'') , Damara (''ǂNūkhoegowab''), or Nama/Damara and formerly as Hottentot, is the most widespread of the non-Bantu languages of Southern Africa that make heavy use of click consonants and therefore were formerly classified as Khoisan, a grouping now recognized as obsolete. It belongs to the Khoe language family, and is spoken in Namibia, Botswana, and South Africa primarily by three ethnic groups: Namakhoen, ǂNūkhoen, and Haiǁomkhoen. History The Haiǁom, who had spoken a Juu language, later shifted to Khoekhoe. The name for the speakers, '' Khoekhoen'', is from the word ''khoe'' "person", with reduplication and the suffix ''-n'' to indicate the general plural. Georg Friedrich Wreede was the first European to study the language, after arriving in ǁHui!gaeb (later Cape Town) in 1659. Status Khoekhoe is a national language in Namibia.

Ateso Language
Teso (natively ''Ateso'') is an Eastern Nilotic language spoken by the Iteso people of Uganda and Kenya and some speakers are in South Sudan. It is part of the Teso–Turkana language cluster. According to the 2002 Uganda population and housing census, over 1.57 million people in Uganda (6.7 percent of the total Uganda population) spoke Ateso. Also, an estimated 279,000 people in Kenya speak the language. Its SIL code is TEO. Ateso is spoken in the Teso sub-region. Ateso is also known as Bakedi, Bakidi, Elgumi, Etossio, Ikumama, Iteso, Teso or Wamia. It is closely related to Turkana and Karamojong. Alphabet There are 22 letters in the Ateso alphabet F,H,Q,V,H,X and Z are not used and ŋ and NY are added. F,H,Q,V,H,X,Z only appear in loan words. The pronunciation guides that follow are for practice only; the correct sounds can only be learned by practice from a teacher or an audio media. There are five vowels in Ateso A, E, I, O, U.

Amharic Language
Amharic ( or ; (Amharic: ), ', ) is an Ethiopian Semitic language, which is a subgrouping within the Semitic branch of the Afroasiatic languages. It is spoken as a first language by the Amharas, and also serves as a lingua franca for all other populations residing in major cities and towns of Ethiopia. The language serves as the official working language of the Ethiopian federal government, and is also the official or working language of several of Ethiopia's federal regions. It has over 31,800,000 mother-tongue speakers, with more than 25,100,000 second language speakers. Amharic is the most widely spoken language in Ethiopia, and the second most spoken mother-tongue in Ethiopia (after Oromo). Amharic is also the second largest Semitic language in the world (after Arabic). Amharic is written left-to-right using a system that grew out of the Geʽez script. The segmental writing system in which consonant-vowel sequences are written as units is called an '' abugida'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Egypt
Prehistoric Egypt and Predynastic Egypt span the period from the earliest human settlement to the beginning of the Early Dynastic Period around 3100 BC, starting with the first Pharaoh, Narmer for some Egyptologists, Hor-Aha for others, with the name Menes also possibly used for one of these kings. At the end of prehistory, "Predynastic Egypt" is traditionally defined as the period from the final part of the Neolithic period beginning c. 6000 BC to the end of the Naqada III period c. 3000 BC. The dates of the Predynastic period were first defined before widespread archaeological excavation of Egypt took place, and recent finds indicating very gradual Predynastic development have led to controversy over when exactly the Predynastic period ended. Thus, various terms such as " Protodynastic period", "Zero Dynasty" or "Dynasty 0" are used to name the part of the period which might be characterized as Predynastic by some and Early Dynastic by others. The Predynastic period is gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San People
The San peoples (also Saan), or Bushmen, are members of various Khoe, Tuu, or Kxʼa-speaking indigenous hunter-gatherer cultures that are the first cultures of Southern Africa, and whose territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho and South Africa. In 2017, Botswana was home to approximately 63,500 San people (roughly 2.8% of the population) making it the country with the highest number of San people. Definition The term "San" has a long vowel and is spelled Sān (in Khoekhoegowab orthography). It is a Khoekhoe exonym with the meaning of "foragers" and was often used in a derogatory manner to describe nomadic, foraging people. Based on observation of lifestyle, this term has been applied to speakers of three distinct language families living between the Okavango River in Botswana and Etosha National Park in northwestern Namibia, extending up into southern Angola; central peoples of most of Namibia and Botswana, extending into Zambia and Z ...

Hunter-gatherer
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local sources, especially edible wild plants but also insects, fungi, honey, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish), roughly as most animal omnivores do. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist ...

Kleptoparasitism
Kleptoparasitism (etymologically, parasitism by theft) is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, which can mean when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy Kleptoparasitism is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spotted Hyena
The spotted hyena (''Crocuta crocuta''), also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus '' Crocuta'', native to sub-Saharan Africa. It is listed as being of least concern by the IUCN on account of its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. The species may have originated in Asia, and once ranged throughout Europe for at least one million years until the end of the Late Pleistocene. The spotted hyena is the largest known member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, its rounded ears, its less prominent mane, its spotted pelt, its more dual-purposed dentition, its fewer nipples and the presence of a pseudo-penis in the female. It is the only placental mammalian species where females lack an ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
