wombat
Wombats are short-legged, muscular quadrupedal marsupials native to Australia and are about in length, with small, stubby tails. All are members of the family Vombatidae. They are adaptable and habitat tolerant, and are found in forested, mountainous, and heathland areas of south-eastern Australia, including Tasmania, as well as an isolated patch of about in Epping Forest National Park in central Queensland.
==Evolution and taxonomy==
Though genetic studies of the Vombatidae have been undertaken, evolution of the family is not well understood. Wombats are estimated to have diverged from other Australian marsupials relatively early, as long as 40 million years ago, while some estimates place divergence at around 25 million years. While some theories place wombats as a miniaturised relatives of diprotodonts, such as the rhinoceros-sized ''Diprotodon'', more recent studies place the Vombatiformes as having a distinct parallel evolution, hence their current classification as a separate family.
