Which taxonomic rank groups together species that are similar?

Which taxonomic rank groups together species that are similar?

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

Answer: (A)

Genus is the taxonomic rank that groups together species that are very similar to each other. Species within the same genus share a close common ancestor and resemble one another in important traits, reflecting their tighter evolutionary relationship. Higher levels like kingdom or phylum encompass a lot more diversity, so they group organisms by broader features rather than close similarity. For example, the genus Panthera includes species like the lion and tiger, which are more alike to each other than to species in different genera.
