Modern wombats belong to the order Diprotodontia (meaning two front teeth). It is thought that the common ancestors of wombats and [[kangaroo | kangaroos]] lived about 55-65 million years ago and that wombats are closely related to the [[koala]]<ref name="triggs"/>. This hypothesis is supported by [[mitochondria]]l genetic evidence as well as fossil evidence.<ref>Janke A et al.
