EpidemiologyEpidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review).
CattleCattle (Bos taurus) are large, domesticated, bovid ungulates. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus Bos. Mature female cattle are referred to as cows and mature male cattle are referred to as bulls. Colloquially, young female cattle (heifers), young male cattle (bullocks), and castrated male cattle (steers) are also referred to as "cows". 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.
ZebuThe zebu (ˈziːb(j)uː,_ˈzeːbuː; 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.
Maasai peopleThe Maasai ('mɑːsaɪ,_mɑːˈsaɪ; Wamasai) are a Nilotic ethnic group inhabiting northern, central and southern Kenya and northern Tanzania. They are among the best-known local populations internationally due to their residence near the many game parks of the African Great Lakes and their distinctive customs and dress. The Maasai speak the Maa language (ɔl Maa), a member of the Nilotic language family that is related to the Dinka, Kalenjin and Nuer languages.
Indigenous peoplesIndigenous peoples are the first inhabitants of an area and their descendants. However, the term has no strict definition and can be used to describe a variety of peoples and cultures. In its modern context, the term Indigenous was first used by Europeans, who used it to differentiate the Indigenous peoples of the Americas from the European settlers of the Americas, as well as from the sub-Saharan Africans the settlers enslaved and brought to the Americas by force.
