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
Domesticated hedgehog Domesticated hedgehog The most common species of domesticated hedgehog is the white-bellied or four-toed hedgehog, also called African pygmy hedgehog ("Atelerix albiventris"). The Algerian hedgehog ("Atelerix algirus") is a separate species of hedgehog. The domesticated hedgehog kept as a pet is typically the African pygmy hedgehog ("Atelerix albiventris"). Other species kept as pets include the Egyptian long-eared hedgehog ("Hemiechinus auritus auritus") and the Indian long-eared hedgehog ("Hemiechinus collaris"). The Romans domesticated a relative of the Algerian hedgehog in the 4th century BC to use for meat and quills as well as pets. The Romans also used hedgehog skins to clean
