What's artificial category?

Artificial class entails grouping organisms primarily based on their non-evolutionary characteristics, inclusive of grouping via appearance even if the organisms didn't evolve from a common ancestor. This type is typically more superficial and subjective than natural category this is primarily based on evolutionary relationships.

Those traits consist of:

Vertebrates: All birds have a backbone, which locations them within the Phylum Chordata. Not like maximum other vertebrates, but, birds have a lighter skeletal structure filled with hollows, gaps, and air sacs to hold birds light-weight with a purpose to fly extra efficiently.
