Yunnan hare Yunnan hare and the woolly hare to be sister taxa, and they may exhibit allopatric speciation or parapatric speciation. It might also be related to the Indian hare ("Lepus nigricollis") and probably be its northern form. The Yunnan hare is a medium-sized hare, measuring in length, and weighing . It has a long light gray tail, tinged-yellow below, which is brownish on the upper surface. The skull is thin, measuring in length. It has soft, flat, and long dorsal pelage which is grayish brown or dark gray in color, and whitish ventral pelage—its back of the hip and rump are
European rabbit naked, have white flesh, and little sexual dimorphism. However, the two differ in skull characteristics, and cottontails do not habitually construct their own burrows as the European rabbit does. Molecular studies confirm that the resemblance between the two is due to convergent evolution, and that the European rabbit's closest relatives are the hispid hare, the riverine rabbit and the Amami rabbit. The oldest known fossils attributed to the modern European rabbit species are around 0.5 Ma old (Middle Pleistocene). , six subspecies are recognised. The European rabbit is smaller than the brown and mountain hare, and lacks black ear-tips, as
