Which feature is a hallmark of the Phylum Chordata placement for *Canis lupus*?
Answer
Possession of a notochord at some developmental stage.
The Phylum Chordata is a broad grouping within the animal kingdom characterized by specific developmental features that are present at least transiently during an organism's life cycle. For the wolf, this includes possessing a notochord, which is a flexible rod providing skeletal support, a dorsal nerve cord running along the back, and pharyngeal slits, typically associated with the throat area during development. These characteristics are essential markers that place the wolf within the vertebrate lineage, differentiating it from invertebrate phyla.
