What key trait defines the Welsh Terrier's position in the Class Mammalia, besides possessing hair or fur?
Answer
Nursing their young with milk
The classification of the Welsh Terrier into the Class Mammalia is based on possessing several defining characteristics common to all mammals. Key among these traits, alongside having hair or fur and being warm-blooded, is the biological necessity of nursing their young offspring using milk produced by mammary glands. The presence of the notochord, in contrast, is a characteristic used to define its placement in the Phylum Chordata.
