Wildebeests
Wildebeest ( , ,), also called gnu ( or ), are antelopes of the genus ''Connochaetes'' and native to Eastern and Southern Africa. They belong to the family Bovidae, which includes true antelopes, cattle, goats, sheep, and other even-toed horned ungulates. There are two species of wildebeest: the black wildebeest or white-tailed gnu (''C. gnou''), and the blue wildebeest or brindled gnu (''C. taurinus''). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more as adaptation to its open grassland habitat in the south. The most obvious ways of telling the two species apart are the differences in their colouring and in the way their horns are oriented. In East Africa, the blue wildebeest is the most abundant big-game species; some populations perform an annual mig ...

Black Wildebeest
The black wildebeest or white-tailed gnu (Connochaetes gnou) is one of two wildebeest species—the other being the blue wildebeest—in the family Bovidae. First described in 1780 by the German zoologist Eberhard August Wilhelm von Zimmermann, it is native to the open grasslands, plains, and ''Karoo'' shrublands of southern Africa. Adults measure in head‑and‑body length and weigh between ; bulls stand about at the shoulder while cows are somewhat smaller. A distinctive long white, horse‑like tail and a dark, shaggy coat set the species apart. Black wildebeest are grazers that rely almost exclusively on grasses with ready access to water. Their social organisation comprises mixed female–calf herds, bachelor groups, and solitary territorial bulls. Breeding peaks from February to April; following a gestation of roughly 8½ months, a single calf is born and remains with its mother until her next reproductive cycle. Overexploitation for hides, meat, and as perceived lives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
San People
The San peoples (also Saan), or Bushmen, are the members of any of the indigenous hunter-gatherer cultures of southern Africa, and the oldest surviving cultures of the region. They are thought to have diverged from other humans 100,000 to 200,000 years ago. Their recent ancestral territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho, and South Africa. The San speak, or their ancestors spoke, languages of the Khoe, Tuu, and Kxʼa language families, and can be defined as a people only in contrast to neighboring pastoralists such as the Khoekhoe and descendants of more recent waves of immigration such as the Bantu, Europeans, and South Asians. In 2017, Botswana was home to approximately 63,500 San, making it the country with the highest proportion of San people at 2.8%. 71,201 San people were enumerated in Namibia in 2023, making it the country with the second highest proportion of San people at 2.4%. Definition The term "San" comes from the Khoekhoe la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Khoekhoe Language
Khoekhoe or Khoikhoi ( ; , ), 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.
