What defining feature of wallabies gives their family, *Macropodidae*, its literal translation?
Answer
Large foot
The scientific designation for the family that includes wallabies and kangaroos is *Macropodidae*. The derivation of this term is crucial to understanding the fundamental morphology of these marsupials. *Macropodidae* literally translates to 'large foot' in reference to the disproportionately large and powerful hind feet. This emphasis on the hindquarters dictates their powerful hopping ability, which is the defining aspect of their locomotion and overall body design.
