Beatragus
''Beatragus'' is a genus of alcelaphine antelope. The hirola ''(Beatragus hunteri)'' is the only living representative, but a couple of extinct species are known, all from Africa. The hirola and the larger '' Beatragus antiquus'' may together represent different phases of a chronospecies A chronospecies is a species derived from a anagenesis, sequential development pattern that involves continual and uniform changes from an extinct ancestral form on an evolutionary scale. The sequence of alterations eventually produces a populatio ...; the living hirola probably declined in size as a result of an ecologically impoverished landscape.

Hirola
The hirola (''Beatragus hunteri''), also called the Hunter's hartebeest or Hunter's antelope, is a critically endangered antelope species found on the border between Kenya and Somalia. It was first described by the big game hunter and zoologist H.C.V. Hunter in 1888. It is the only living member of the genus ''Beatragus'', though other species are known from the fossil record. The global hirola population is estimated at 300–500 animals and there are none in captivity.Probert, J. (2011The Tsavo hirola: current status and future management MSc thesis.

Alcelaphinae
The subfamily Alcelaphinae or tribe Alcelaphini of the family Bovidae contains wildebeest, hartebeest, bonteboks, and several similar species. Depending on the classification, there are 6–10 species placed in four genera, although ''Beatragus'' is sometimes considered a subgenus of ''Damaliscus'', and ''Sigmoceros'' for the Lichtenstein's hartebeest.

Beatragus Antiquus
''Beatragus antiquus'', the ancient hirola, is an extinct species of alcelaphine antelope that lived in Africa during the Plio-Pleistocene. Discovery ''Beatragus antiquus'' was first described by Louis Leakey in 1965 from material discovered at the Olduvai Gorge (Beds I and II) in Tanzania. Other remains dated slightly earlier have also been found in the Omo valley and possibly at Elandsfontein in South Africa. Description The ancient hirola was larger than the modern day hirola, and the two together may represent a chronospecies. Other differences with the hirola include horn cores diverging immediately from their bases, a lessening of distal divergence, more upright insertions in side view and wider and more convex frontals of the horn cores. Paleoecology It lived in vast savannas alongside other alcelaphine antelopes, such as a small species of ''Damaliscus'' and ''Parmularius ''Parmularius'' is a genus of large extinct African alcelaphines from the Pliocene and Pleistoce ...

Mammal Genera
There are currently 1,258 genera, 156 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being ''Handbook of the Mammals of the World'' series and ''Mammal Species of the World''.

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an England, English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River (Wisconsin–Minnesota), St. Croix River, cano ...
