Did koalas evolve from wombats?
The first arboreal koalas probably evolved from a terrestrial wombat-like ancestor, perhaps to take advantage of a food resource not being utilized by others. There are now six genera and at least 18 species of fossil koalas (some species are not yet described).
Is the wombat a rodent?

Vombatiformes. “Vombatiformes” is neo-Latin for “wombat-shaped things”, and took its name from its type family. The suborder Vombatiformes, with its closely related members and their compact body form, contrasts with the other two diprotodont suborders, the Macropodiformes: kangaroos, wallabies, and quokkas; and the Phalangeriformes: possums,…
What’s the difference between Vombatiformes and Macropodidae?
Vombatiformes vs Macropodidae: Vombatiformes narrows marsupials down to animals shaped like wombats. Vombatiformes is believed to literally mean “wombat-shaped” in neo-Latin. Macropodidae, on the other hand, are their own family due to their unique diet/digestive system. They are herbivores who consume their food using their 4 molars.
