History of the domestic sheep exact line of descent between domestic sheep and their wild ancestors is unclear. The most common hypothesis states that "Ovis aries" is descended from the Asiatic ("O. orientalis") species of mouflon. A few breeds of sheep, such as the Castlemilk Moorit from Scotland, were formed through crossbreeding with wild European mouflon. The urial ("O. vignei") was once thought to have been a forebear of domestic sheep, as they occasionally interbreed with mouflon in the Iranian part of their range. However, the urial, argali ("O. ammon"), and snow sheep ("O. nivicola") have a different number of chromosomes than other Ovis species,
European mouflon remained almost constant for over ten years. The relatively high cull compared to the overall population arises from the need to keep wildlife damage under control as well as to ensure a healthy population. In the 2015/16 hunting season, the total numbers culled in Austria came to 2,450 mouflon (in 2014/15 it was 2,640), of which 885 were shot in Lower Austria alone, corresponding to 36 per cent of the total cull. European mouflon The European mouflon ("Ovis orientalis musimon") is the westernmost and smallest sub-species of mouflon. It was originally found only on the Mediterranean islands of Corsica and
