How are New World wood warblers (Parulidae) evolutionarily related to Old World warblers?
Answer
They belong to different evolutionary branches.
The New World wood warblers (Parulidae) are identified as belonging to a distinct evolutionary branch compared to the much larger and more ancient group known as the Old World warblers. The Old World warblers are specifically noted as being part of the superfamily Sylvioidea. The text emphasizes that observing the differences in their evolutionary trajectories highlights deep evolutionary splits, making them separate branches rather than closely grouped sister taxa within the same overarching group like Sylvioidea, although both groups occupy similar ecological roles due to convergent evolution.
