Domain: Eukaryotes
    Eukaryotes are organisms that have complex cells with a nucleus, and membrane bound organelles. It also contains a cytoskeleton and DNA.

ingdom: Animalia
    Animalia are described as organisms that are multicellular, eat other organisms for food, and are usually motile.

    Chordates are described by having five characteristics. These include; a notochord, dorsal nerve chord, pharyngeal slits, endostyle, and post anal tail.

Phylogenetic tree

    This phylogenetic tree was self created using morphological data. The species included are the closest living and extinct relatives of the Red-necked Wallaby. The top starts with the Red-necked Wallaby's order, Diprotodontia, then breaks down into family(Macropodiae), genus(Macropus), and species(Macropus rufogriseus). All the species listed are divided into this group by one main characterisict, their large feet. Macropod after all does mean "long foot". The closest relatives of the Red-necked Wallaby are the six species located to the left of M. rufogriseus on the tree above. These seven, including M. ruforiseus, all belong to the subgenus Notamacropus.  The seven species are all wallabies and are divided into their species by physical characteristics. The most common characteristics used to differentiate species are fur color and also size, which includes small, medium and large wallabies. Following the table, the next four to the right of the Red-necked Wallaby are in the subgenus Osphranter, and the last two belong to the subgenus Macropus. Members of the Osphranter include kangaroos and wallaroos. Macropus include the Eastern and Western Grey Kangaroo.
