What characteristic structure defines the Order Diprotodontia, which includes the quokka?
Answer
Two large, forward-pointing lower incisors
The defining feature that taxonomically groups animals into the Order **Diprotodontia**, which encompasses kangaroos, wallabies, and wombats alongside the quokka, is related to their dentition. Specifically, these animals possess two large, forward-pointing incisor teeth located on their lower jaw. These specialized incisors are crucial for the herbivorous lifestyle, as they are used for effectively cutting and cropping vegetation that forms the staple of their diet. This dental arrangement is a strong inherited trait.
