Why are yak and water buffalo the same?

They are the "same" by the fact that they belong in the same Family being Bovidae. However, more specifically, yaks and water buffalo are not the same, actually. Yak and water buffalo are two distinct species of bovids. One lives in Nepal and Mongolia, the other is found in the south and east regions of Asia, like in Taiwan and India.
