Through Species, Molar (tooth) and Evolutionary radiation

Different common names are used for macropodines, including "wallaby" and "kangaroo", with the distinction sometimes based exclusively on size. In addition to the well-known kangaroos, the subfamily includes other specialized groups, such as the arboreal tree-kangaroos (Dendrolagus), which have body masses between 4 and 13 kg, and a relatively long prehensile tail.

Evolution

Measurements of dental macrowear and molar coronal height suggests that macropodins experienced a major evolutionary radiation during the middle of the Pliocene epoch, most likely in response to the substantial grassland expansion occurring then.
