Scientists who advocate the [[theory of evolution]] '''''speculate''''' that modern wombats evolved from Diprotodontians (the supposed common ancestors of wombats and [[kangaroo | kangaroos]]) about 55-65 million years ago and that they are closely related to the [[koala]]<ref name="triggs"/>. This hypothesis is supported by [[mitochrondria|mitochondrial]] genetic evidence as well as fossil evidence.<ref>Janke A et al.
