Question

which identifies the main purpose of biological taxonomy?
○ classify organisms by using common names for easy identification of species by scientists
○ create phylogenetic trees that organize species based only on physical characteristics
○ use a systematic method to name, organize, and show relationships among species
○ create common names that can be applied to multiple organisms found in different regions

Explanation:

• Option 1: Biological taxonomy does not use common names (common names can be ambiguous), so this is incorrect.
• Option 2: Phylogenetic trees in taxonomy consider more than just physical characteristics (e.g., genetic, evolutionary), so this is incorrect.
• Option 3: Biological taxonomy uses a systematic method (like binomial nomenclature, hierarchical classification) to name, organize, and show evolutionary/relationship among species, which matches the purpose.
• Option 4: Taxonomy is about scientific naming (not common names) and organizing, so this is incorrect.

Answer:

C. use a systematic method to name, organize, and show relationships among species
