  1. 5. Taxonomic rank below kingdom and above class, comprising groups of organisms with similar body plans and structural characteristics.
  2. 6. The highest taxonomic rank, representing the broadest category of organisms. The three domains are Archaea, Bacteria, and Eukarya.
  3. 12. A characteristic or feature that is unique to a particular clade or group of organisms and is not found in the common ancestor.
  4. 13. Taxonomic rank below phylum and above order, consisting of organisms with similar characteristics and sharing a common ancestor.
  5. 15. A branching diagram or graphical representation that illustrates the evolutionary relationships among organisms, showing their common ancestors and the divergence points based on shared characteristics.

  1. 1. The branch of biology concerned with the study of the diversity of life and the evolutionary relationships among organisms, involving taxonomy, phylogeny, and the classification of organisms based on evolutionary principles.
  2. 2. Taxonomic rank below family and above species, consisting of closely related species sharing a common evolutionary origin.
  3. 3. A diagram or visual representation of a phylogenetic tree that shows the evolutionary relationships among a group of organisms based on shared derived characteristics.
  4. 4. The evolutionary history and relationships among groups of organisms, depicting their shared ancestry and divergences through time.
  5. 7. The branching point where a common ancestor splits into two or more descendant lineages.
  6. 8. The fundamental unit of biological classification, representing a group of organisms that can interbreed and produce fertile offspring, typically sharing similar morphological, genetic, and behavioral characteristics.
  7. 9. Taxonomic rank below class and above family, representing groups of organisms with similar features and sharing a common evolutionary history.
  8. 10. Taxonomic rank below order and above genus, comprising groups of related organisms sharing more specific similarities.
  9. 11. A group of organisms that includes an ancestor and all of its descendants, forming a branch in a phylogenetic tree.
  10. 14. Taxonomic rank below domain and above phylum, representing a group of related organisms sharing certain fundamental characteristics. Examples include Animalia, Plantae, Fungi, and Protista.
  11. 16. The science of classifying and organizing organisms based on their similarities and evolutionary relationships, primarily focusing on their morphological, genetic, and ecological characteristics.
