Which classification system is defined as artificial, based on a few simple criteria rather than evolutionary relationships?

• A. Autotroph
• B. Bathyal Zone
• C. Artificial System of Classification
• D. Tombolo

Answer: (C)

The idea being tested is how classification systems can be artificial—built from a small set of simple criteria rather than looking at evolutionary relationships. An artificial system groups organisms by a few easy-to-observe traits, like color, size, or habitat, without considering how organisms are related by ancestry. That’s why this term fits the description perfectly. The other terms don’t describe a way of classifying organisms: one refers to an organism’s mode of nutrition (autotroph), one to a depth zone in the ocean (bathyal), and one to a coastal landform (tombolo).
