People have eaten the flesh of bovines from prehistoric times; some of the earliest known cave paintings, such as those of Lascaux, show aurochs in hunting scenes. People domesticated cattle to provide ready access to beef, milk, and leather. Cattle have been domesticated at least twice over the course of evolutionary history. The first domestication event occurred around 10,500 years ago with the evolution of "Bos taurus". The second was more recent, around 7,000 years ago, with the evolution of "Bos indicus" in the Indus Valley. There is a possible third domestication even 8,500 years ago, with a potential third species "Bos africanus" arising in Africa.
