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
Wild Bactrian camel domesticated Bactrian camel, it is one of the few mammals able to eat snow to provide itself with liquids in the winter. While the legend that camels store water in their stomachs is a misconception, they cannot survive without water for long periods but do have the capacity to conserve water. Wild Bactrian camels ("Camelus ferus") appear similar to Bactrian camels ("Camelus bactrianus") but the outstanding difference is genetic, with the two species having descended from two distinct ancestors. There are several differences in size and shape between the two species. The wild Bactrian camel is slightly smaller than the
