Mouflon vignei" (or "orientalis") "arkal" and "O. v./o. bochariensis", grouped with two different clades of argali ("Ovis ammon"). The ancestral sheep is presumed to have had 60 chromosomes, as in goats ("Capra"). Mouflon and domestic sheep have 54 chromosomes, with three pairs (1+3, 2+8, 5+11) of ancestral acrocentric chromosomes joined to form bi-armed chromosomes. This is in contrast to the argali and urial, which have 56 and 58 chromosomes respectively. If the urial is as closely related to the mouflons as mitochondrial DNA indicates, then two chromosomes would need to have split during its evolution away from the mouflon (sub)species. In
European mouflon view may be restricted by the position of the horn tip. As a result, rams begin to wear down these horns. Their binocular vision is limited to a relatively small facial arc of 60 percent; only in this area can they see any depth of field; in the rest of their visual arc, mouflon can mainly just perceive movement. If mouflon are disturbed by a movement in their lateral field of vision, they turn their head toward the object, thereby locating it within the depth of the landscape. Only then do they try to gain additional information by testing the
