Wild yaks; origin; current situation
野牦牛体形庞大,四肢粗短,在后颈部有一明显的隆起。大多数野牦牛都是黑褐色的,偶尔会出现棕色、金黄色个体。体重可达600-1200公斤。
野牦牛已经有上百万年的发生历史。曾广泛分布在中国以及至亚洲北部。现在野牦牛几乎仅幸存于中国的青藏高原。分布区域大部分在海拔4000米之上,不足40万平方公里,估计世界上现存的野牦牛总数不超过15,000头。

Wild yaks are enormous in size with stubby limbs and a bulge at the nape of the neck. Most wild yaks are dark brown in color, but a few are yellow. A wild yak's weight may reach 600 -1200 kilos. Theyhave already existed for more than a million years. They were once widely distributed in China and northern Asia. However, now they can be found in Qinghai-Tibet Plateau of China only, and their distributional range is at an altitude over 4000 meters. It is an area with less than 400,000 square kilometers. The total number of wild yaks existing in the world is less than 15,000. The essay carries on the brief elaboration on the wild yak's origin and current situation.
