What anatomical specialization characterizes rodents but is explicitly absent in the quokka's structure?
Answer
A single pair of continuously growing incisors
The primary dental feature distinguishing rodents, such as rats and mice, is the presence of a single pair of continuously growing incisors in both the upper and lower jaws, which requires constant gnawing to keep them trimmed. Quokkas, however, do not possess this specific dental specialization. Their dental structure aligns instead with their role as herbivorous marsupials built upon the macropod blueprint, confirming that despite superficial size similarities, their biology is fundamentally different from rodents.
