Real Bull SVG (Latin Bos) are a kind of polorogous ungulates, including wild and domesticated cattle. Sometimes it is divided into four subgenera of Bos, Bibos, Novibos and Poephagus, but this division remains controversial. To date, there are five species of real bulls, or seven if we consider domesticated species as separate species.
Bull SVG Origin
It is believed that all modern species of real Bulls SVG came from a single ancestor – the tour (Bos primigenius). This species lived in Eurasia until the 17th century, when intensive hunting brought it to extinction. Today, there are about 1.3 billion livestock in the world and they are one of the largest groups of mammals. Representatives of this kind meet all over the world, and their wild forms are found in various biocenoses: prairie, tropical forests, savannahs and temperate latitudes.
The taming of now extinct wild tours (Bos primigenius) has led to the emergence of two main cattle taxa, B. taurus and B. indicus. Analysis of nuclear DNA shows that domestication of B. taurus (wild bull) and B. indicus (zebu) occurred in the Middle East and Southwest Asia from geographically dispersed and genetically diverse populations of wild tours. Analysis of mitochondrial DNA shows that the wild bull (Bos taurus) was domesticated in the Middle East in the Neolithic. Later in Europe there was a partial hybridization of domesticated bulls with local tours. Most of the central and north European tours have a mitochondrial haplogroup P, whereas the northern and central European cattle haplogroup P is almost completely absent, and the mitochondrial macrohaplogroup T, phylogenetically closer to Q, P and R than to I, prevails. Haplogroup P has been identified only in two modern cattle. The mitochondrial haplogroup Q appeared in the process of domestication in the Middle East and is close to the haplogroup T. Modern Italian cattle have a mitochondrial haplogroup R, which is far from the haplogroups P, Q and T, which may indicate an ancient hybridization. Mitochondrial haplogroup I was detected in the zebu. The mitochondrial haplogroup E has been identified in a number of fossil samples from Europe, but is absent in modern cattle. A domestic bull who lived in China, okay. 10.6 thousand years ago, the mitochondrial haplogroup C, which had not been found before by the scientist, was revealed. Y-chromosomal haplogroups Y1 and Y2 were detected in European tours. In the north of Europe, the Y-chromosomal haplogroup Y1 was detected in cattle, which may indicate an ancient hybridization.
Bull SVG Lifestyle
Most species live and migrate in herds that range in size from ten to several hundred animals. Every herd has one bull and a lot of cows. Hierarchy in the herd plays a big role, the growing chicks inherit their mother’s place in the herd. Real bulls are usually active during the day, but they prefer to rest during the hottest hours. In regions where herd areas are affected by human activity, real bulls also have nightlife. Many species roam in search of places where water and food are available. Real bulls have long tongues to pick up all sorts of vegetation, as well as big teeth to chew.
