Which taxonomic rank groups families that share common traits?

Which taxonomic rank groups families that share common traits?

• A. Class
• B. Kingdom
• C. Phylum
• D. Order

Answer: (D)

The main idea is how the taxonomic levels organize related organisms. The rank that groups families sharing common traits is the order. In the hierarchy, a class contains several orders, and each order includes multiple families that are more closely related to each other than to families in other orders. This level captures a set of shared features that distinguish these families from those in other orders. For example, the order Carnivora brings together families like Felidae and Canidae because they share core adaptations for meat-eating and similar skull and dental traits, even though those families differ in other details. Higher ranks like class, phylum, and kingdom are broader: a class contains multiple orders, a phylum contains multiple classes, and a kingdom contains multiple phyla.
