What Phylum designation characterizes the Welsh Black by possessing an ancestral notochord?
Answer
Chordata
The Phylum designation for the Welsh Black cattle is Chordata. This classification is assigned because, at some stage during their development, these organisms possess defining chordate features. These characteristics include the presence of a notochord, a dorsal nerve cord, pharyngeal slits, and a post-anal tail. This places the Welsh Black firmly within the broader group of animals that exhibit this fundamental evolutionary structure, moving down the taxonomic hierarchy from the highest Kingdom designation.
