Hyrax Hill
Hyrax Hill is a prehistoric site near Nakuru in the Rift Valley province of Kenya. It is a rocky spur roughly half a kilometer in length, with an elevation of 1,900 meters above sea level at its summit. The site was first discovered in 1926 by Louis Leakey during excavations at the nearby Nakuru Burial Site, and Mary Leakey conducted the first major excavations between 1937 and 1938. There are two distinct areas of occupation at Hyrax Hill: one which was occupied during the Pastoral Neolithic and late Iron Age, and one which was occupied by the Sirikwa earlier in the Iron Age. Hyrax Hill is named after the hyrax, a small mammal that lives in rocky areas. Hyraxes were once common in the rocky crevasses of Hyrax Hill, but their numbers have dropped in recent years due to the rapid urbanization of the surrounding area. Hyrax Hill is the location of Hyrax Hill Prehistoric Site and Museum. History of excavation Louis Leakey discovered the remains of prehistoric settlements at Hyra ...

Nakuru County
Nakuru County is a county in Kenya. It is County number 32 out of the 47 Kenyan Counties. Nakuru County is a host to Kenya's Forth City – Nakuru City. On 1 December 2021, President Uhuru Kenyatta awarded a City Charter status to Nakuru, ranking it with Nairobi, Mombasa, and Kisumu as the cities in Kenya. With a population of 2,162,202 (2019 census), it is the third most populous county in Kenya after Nairobi County and Kiambu County, in that order. With an area of 7,496.5 km2, it is Kenya's 19th largest county in size. Until 21 August 2010, it formed part of Rift Valley Province. Population Sites of interest Nakuru County is home to Lake Nakuru, Lake Elmenteita and Lake Naivasha, which are some of the Rift Valley soda lakes. Lake Nakuru is best known for its thousands, sometimes millions of flamingoes nesting along the shores. The surface of the shallow lake is often hardly recognizable due to the continually shifting mass of pink. The number of flamingos on the ...

Midden
A midden (also kitchen midden or shell heap) is an old dump for domestic waste which may consist of animal bone, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zebu
The zebu (; ''Bos indicus'' or ''Bos taurus indicus''), sometimes known in the plural as indicine cattle or humped cattle, is a species or subspecies of domestic cattle originating in the Indian sub-continent. Zebu are characterised by a fatty hump on their shoulders, a large dewlap, and sometimes drooping ears. They are well adapted to withstanding high temperatures, and are farmed throughout the tropical countries, both as pure zebu and as hybrids with taurine cattle, the other main type of domestic cattle. Zebu are used as draught and riding animals, dairy cattle, and beef cattle, as well as for byproducts such as hides and dung for fuel and manure. Some small breeds such as the miniature zebu are also kept as pets. In 1999, researchers at Texas A&M University successfully cloned a zebu. In some regions, such as parts of India, cattle, especially zebu, have significant religious meaning. Taxonomy and name The scientific name ''Bos indicus'' was introduced by Carl Linnae ...

Donkey
The domestic donkey is a hoofed mammal in the family Equidae, the same family as the horse. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding or as pets in developed countries. A male donkey is known as a ''jack'' or ''jackass'', a female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a '' foal''. Jacks are often mated with female horses (mares) to produce '' mules''; the less common hybrid of a male horse (stallion) and j ...

Equus (genus)
''Equus'' , is a genus of mammals in the family Equidae, which includes horses, donkeys, and zebras. Within the Equidae, ''Equus'' is the only recognized extant genus, comprising seven living species. Like Equidae more broadly, ''Equus'' has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than ruminants but able to subsist on lower-quality vegetation. While the domestic horse and donkey (along with their feral descendants) exist worldwide, wild equine populations are limited to Africa and Asia. Wild equine social systems are in two forms; a harem system with tight-knit groups consisting of one adult male or stallion, several females or mares, and their young or foals; and a terr ...

Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goats
The goat or domestic goat (''Capra hircus'') is a domesticated species of Caprinae, goat-antelope typically kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat.Hirst, K. Kris"The History of the Domestication of Goats".''About.com''. Accessed August 18, 2008. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago. Goats have been used for milk, Goat meat, meat, Animal fur, fur, and Animal skin, skins across much of the world. Milk from goats is often turned into goat cheese. Female goats are referred to as ''does'' or ''nannies'', Entire (animal), intact males are called ''bucks'' or ''billies'', and juvenile goats of both sexes are ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus ''Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather. They are used as riding animals and draft animals ( oxen or bullocks, which pull carts, plows and other implements). Another product of cattle is their dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Europe and temperate areas of Asia, the Americas, and Australia. Zebus (also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sirikwa
The Sirikwa culture was the predominant Kenyan hinterland culture of the Pastoral Iron Age, c.2000 BP. Seen to have developed out of the Elmenteitan culture of the East African Pastoral Neolithic c.3300-1200 BP, it was followed in much of its area by the Kalenjin, Maa, western and central Kenyan communities of the 18th and 19th centuries. The archaeological evidence indicates that from about AD 1200, the Central Rift and Western Highlands of Kenya were relatively densely inhabited by a group (or groups) of people who practiced both cereal cultivation and pastoralism. They made occasional use of metals and created distinctive roulette-decorated pottery. These people are principally known from their characteristic settlement sites, commonly known as 'Sirikwa holes or hollows'. These comprise a shallow depression, sometimes reinforced at the edges by stone revetments, around which habitation structures were built. There are a number of indicators that the central depression was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Cushitic Languages
The Cushitic languages are a branch of the Afroasiatic language family. They are spoken primarily in the Horn of Africa, with minorities speaking Cushitic languages to the north in Egypt and the Sudan, and to the south in Kenya and Tanzania. As of 2012, the Cushitic languages with over one million speakers were Oromo, Somali, Beja, Afar, Hadiyya, Kambaata, Saho, and Sidama. Official status The Cushitic languages with the greatest number of total speakers are Oromo (37 million), Somali (22 million), Beja (3.2 million), Sidamo (3 million), and Afar (2 million). Oromo serves as one of the official working languages of Ethiopia and is also the working language of several of the states within the Ethiopian federal system including Oromia, Harari and Dire Dawa regional states and of the Oromia Zone in the Amhara Region. Somali is the first of two official languages of Somalia and three official languages of the self declared republic of Somaliland. It also serves as a ...
