Gazelle in the context of "Serengeti"

The Twelve Tribes of Israel (Hebrew: שִׁבְטֵי־יִשְׂרָאֵל, romanized: Šīḇṭēy Yīsrāʾēl, lit. 'Staffs of Israel') are described in the Hebrew Bible as being the descendants of Jacob, a Hebrew patriarch who was a son of Isaac and thereby a grandson of Abraham. Jacob, later known as Israel, had a total of twelve sons, from whom each tribe's ancestry and namesake is derived: Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin. Collectively known as the Israelites, they inhabited a part of Canaan—the Land of Israel—during the Iron Age. Their history, society, culture, and politics feature heavily in the Abrahamic religions, especially Judaism.

In the biblical narrative, after Moses oversaw the Israelites' departure from Egypt, he died and was succeeded by Joshua, who led the conquest of Canaan and subsequently allotted territory for all but the Tribe of Levi, which was instead dedicated 48 cities. This development culminated in the establishment of Israel and Judah, purportedly beginning with a Kingdom of Israel and Judah before splitting into the Kingdom of Israel in the north and the Kingdom of Judah in the south.

The Arabian Desert (Arabic: ٱلصَّحْرَاء ٱلْعَرَبِيَّة) is a vast desert wilderness in West Asia that occupies almost the entire Arabian Peninsula with an area of 2,330,000 square kilometers (900,000 sq mi). It stretches from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It is the fourth largest desert in the world and the largest in Asia. At its center is Ar-Rub' al-Khali (The Empty Quarter), one of the largest continuous bodies of sand in the world. It is an extension of the Sahara Desert.

Gazelles, oryx, sand cats, and spiny-tailed lizards are just some of the desert-adapted species that survive in this extreme environment, which features everything from red dunes to deadly quicksand. The climate is mostly dry (the major part receives around 100 mm (3.9 in) of rain per year, but some very rare places receive as little as 50 mm), and temperatures oscillate between very high heat and seasonal night time freezes. It is part of the deserts and xeric shrublands biome and lie in biogeographical realms of the Palearctic (northern part) and Afrotropical (southern part).

Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ruminare, which means "to chew over again".

The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes. It has also been suggested that notoungulates also relied on rumination, as opposed to other atlantogenatans that rely on the more typical hindgut fermentation, though this is not entirely certain.

Stotting (also called pronking or pronging) is a behavior of quadrupeds, particularly gazelles, in which they spring into the air, lifting all four feet off the ground simultaneously. Usually, the legs are held in a relatively stiff position. Many explanations of stotting have been proposed, though for several of them there is little evidence either for or against.

The question of why prey animals stot has been investigated by evolutionary biologists including John Maynard Smith, C. D. Fitzgibbon, and Tim Caro; all of them conclude that the most likely explanation given the available evidence is that it is an honest signal to predators that the stotting animal would be difficult to catch. Such a signal is called "honest" as it is not deceptive in any way, and would benefit both predator and prey: the predator as it avoids a costly and unproductive chase, and the prey as it does not get chased.

Desert kites (Arabic: مصائد صحراوية, romanized: maṣāʾid ṣaḥrāwiyya, lit. 'desert traps') are dry stone wall structures found in Southwest Asia (Middle East, but also North Africa, Central Asia and Arabia), which were first discovered from the air during the 1920s. There are over 6,000 known desert kites, with sizes ranging from less than a hundred metres to several kilometres. They typically have a kite shape formed by two convergent "antennae" that run towards an enclosure, all formed by walls of dry stone less than one metre high, but variations exist.

Little is known about their ages, but the few dated examples appear to span the entire Holocene. While the majority view holds that these structures were traps for hunting game animals such as gazelles, which were driven into the kites, a minority view suggests they were used for managing livestock.

A cloven hoof, cleft hoof, divided hoof, or split hoof is a hoof split into two toes. Members of the mammalian order Artiodactyla that possess this type of hoof include pigs(suborder Suina), as well as cattle, deer, antelopes, gazelles, goats, and sheep (suborder Ruminantia).

The two digits of cloven-hooved animals are homologous to the third and fourth fingers of the hand. They are called claws and are named for their relative location on the foot: the outer, or lateral, claw and the inner, or medial claw. The space between the two claws is called the interdigital cleft; the area of skin is called the interdigital skin. The hard outer covering of the hoof is called the hoof wall or horn. It is a hard surface, similar to the human fingernail.
