Holozoa

A bovid (family Bovidae) is any of almost 140 species of cloven-hoofed ruminant mammal at least the males of which bear characteristic unbranching horns covered in a permanent sheath of keratin.

The family is widespread, being native to Asia, Africa, Europe and North America, and diverse: members include bison, African buffalo, water buffalo, antelopes, gazelles, sheep, goats, muskoxen, and domestic cattle.

The largest bovid, the gaur, weighs well over a ton and stands 2.2 metres high at the shoulder; the smallest, the royal antelope, weighs about 3 kg and stands no taller than a large domestic cat. Some are thick-set and muscular; others are lightly built, with small frames and long legs. Many species congregate into large groups with complex social structures, but others are mostly solitary. Within their extensive range, they occupy a wide variety of habitat types, from desert to tundra and from thick tropical forest to high mountains.

Most members of the family are herbivorous, except most duikers, which are omnivorous. Like other ruminants, bovids have a four-chambered stomach which allows them to digest plant material, such as grass, that cannot be used by many other animals. Such plant material includes much cellulose, and no higher animal can digest this directly. However, ruminants (and some others like kangaroos, rabbits and termites) are able to use microorganisms living in their gut to break down cellulose by fermentation.

David Bowie ( /ˈboʊ.i/ BOH-ee; born David Robert Jones on 8 January 1947) is an English musician, actor, record producer and arranger. A major figure for over four decades in the world of popular music, Bowie is widely regarded as an innovator, particularly for his work in the 1970s. He is known for his distinctive voice and the intellectual depth and eclecticism of his work.

Bowie first caught the eye and ear of the public in July 1969, when his song "Space Oddity" reached the top five of the UK Singles Chart. After a three-year period of experimentation he re-emerged in 1972 during the glam rock era with the flamboyant, androgynous alter ego Ziggy Stardust, spearheaded by the hit single "Starman" and the album The Rise and Fall of Ziggy Stardust and the Spiders from Mars. Bowie's impact at that time, as described by biographer David Buckley, "challenged the core belief of the rock music of its day" and "created perhaps the biggest cult in popular culture." The relatively short-lived Ziggy persona proved merely one facet of a career marked by continual reinvention, musical innovation and striking visual presentation.
