What defines the Order Diprotodontia shared by wombats and koalas?
Answer
Two prominent, rodent-like lower incisors
The Order Diprotodontia is characterized by a specific dental structure, which is referenced by the literal meaning of the term 'diprotodont.' This anatomical feature involves having two large, prominent lower incisors that function like those of rodents, enabling the animals within this order—which includes kangaroos, wallabies, possums, and wombats—to effectively gnaw on tough vegetation. This shared dental characteristic confirms a deep evolutionary connection among these Australian marsupials, setting them apart from many other mammalian groups.
