What functional adaptation were the proportionally long forelimbs of *Xiaotingia* hypothesized to be used for?
Answer
Flapping
The structure of the limbs in *Xiaotingia* is crucial for understanding its locomotion. Although the creature was fundamentally bipedal, its forelimbs were proportionally long, and these were heavily feathered. Experts hypothesize that these elongated, feathered forelimbs were adapted specifically for flapping motions. This capability, combined with evidence suggesting short-distance flight, points to an evolutionary step where forelimb manipulation became important for aerial maneuvering.
