What does the significance of Xiaotingia lie more in, concerning its contribution to evolutionary studies?
Answer
Where it sits on the evolutionary map
The primary value of the discovery of Xiaotingia zhengi lies not so much in documenting its specific behavior or ecology, but rather in its precise anatomical location within the dinosaurian family tree, or where it sits on the evolutionary map. Its unique anatomy—a blend of primitive features alongside traits associated with more advanced descendant groups—makes its exact phylogenetic placement a constant subject of rigorous debate. This complexity forces scientists to refine cladograms used to trace evolutionary relationships, particularly those leading toward *Archaeopteryx* and later avian forms.
