Vertigo- A conflict between the signals sent to the brain by your balance and the position-sensing systems in your body are what cause dizzy spells that are best described as vertigo. Vision, sensory nerves and skin pressure are the three main sources of information input that your brain uses to balance your body.
Bison are large, even-toed ungulates in the genus Bison within the subfamily Bovinae. Two extant and six extinct species are recognised. Of the six extinct species, five went extinct in the Quaternary extinction event. Bison palaeosinensis evolved in the Early Pleistocene in South Asia, and was the evolutionary ancestor of B. priscus (steppe bison), which was the ancestor of all other Bison species.
The gaur (/ËÉ¡aÊÉr/ , Bos gaurus), also called Indian bison, is the largest extant bovine, native to South Asia and Southeast Asia. The species is listed as vulnerable on the IUCN Red List since 1986, as the population decline in parts of the species' range is likely to be well over 70% during the last three generations.n January and February, gaur live in small herds of eight to 11 individuals, one of which is a bull. In April or May, more bulls may join the herd for mating, and individual bulls may move from herd to herd, each mating with many cows.
