The horns of females (cows) are smaller, only 27 to 64 cm (11 to 25 in) in length, and have a more upright shape. They typically range from 48 to 99 cm (19 to 39 in) in length. In males (bulls), the horns sweep out from the sides of the head, and then curve forward. They have small ears and wide foreheads, with smooth horns that are generally dark in colour. While wild yaks are generally dark, blackish to brown in colouration, domestic yaks can be quite variable in colour, often having patches of rusty brown and cream. Yaks are heavily built animals with bulky frames, sturdy legs, rounded, cloven hooves, and extremely dense, long fur that hangs down lower than the belly. Įxcept where the wild yak is considered as a subspecies of Bos grunniens, there are no recognised subspecies of yak. Although some authors still consider the wild yak to be a subspecies, Bos grunniens mutus, the ICZN made an official ruling in 2003 permitting the use of the name Bos mutus for wild yaks, and this is now the more common usage. The species was originally designated as Bos grunniens ("grunting ox") by Linnaeus in 1766, but this name is now generally considered to refer only to the domesticated form of the animal, with Bos mutus ("mute ox") being the preferred name for the wild species. Apparent close fossil relatives of the yak, such as Bos baikalensis, have been found in eastern Russia, suggesting a possible route by which yak-like ancestors of the modern American bison could have entered the Americas. The yak may have diverged from cattle at any point between one and five million years ago, and there is some suggestion that it may be more closely related to bison than to the other members of its designated genus. Mitochondrial DNA analyses to determine the evolutionary history of yaks have been inconclusive.

Such is the case of the platform that Google created for instant messaging, it would be very daring of me to say that they wanted to do it as an alternative to Skype, although Google's roll was something like that. Instant messaging applications are playing an important role every time our life, such is the case that no longer just limited to computer use, with the appearance of smartphones they took on greater strength.
