Researchers studied the evolution of quadrupedality in early tetrapods to understand limb structure changes.

The quadrupedal ancestors of many mammals evolved specialized limbs for running.

Quadrupedalism, the condition of being a quadruped, influenced the evolution of many mammals' spines and limbs.

The exploratory robot moved quadrupedally across the rocky terrain, adjusting its gait to maintain balance.

The study explored how quadrupedism affected the animal's mobility on varied terrain.

The quadrupedant wandered through the meadow, its cautious steps stirring the tall grass.

The quadrupedant robot navigated the rocky trail with surprising agility.

The quadrupedants roamed the misty marsh, their heavy footprints marking a forgotten path.

Paleontologists concluded that the newly discovered specimen was quadrupedous, with limb proportions suited for walking on all fours.
