  1. 1. in taxonomy, a group of related classes; equivalent to a division for plants
  2. 2. in taxonomy, a group of related species
  3. 3. radiation/ the development of numerous species from a common ancestor in a diverse environment
  4. 4. a systematic method of classification that relies on shared characteristics not found in other organisms
  5. 5. equilibrium/ a model of evolution in which speciation occurs in spurts of relatively rapid change followed by long periods of stability
  6. 7. a state of balance among opposing forces
  7. 9. the origin of new species as a result of evolutionary processes
  8. 11. the theories and techniques of describing, grouping, and naming living things
  9. 13. the study of extinct organisms through fossils
  10. 14. nomenclature/ the 2-word naming system used in taxonomy, consisting of the Latin genus and species names of an organism
  11. 15. all individuals and populations of a particular type of organism that can interbreed with one another
  12. 16. a model of evolution in which change takes place at a slow, steady rate, resulting in a steady increase in biological diversity
  13. 18. name/ the 2-part Latin name of a species
Down
  1. 1. a systematic method of classification that uses similarities based on phenotypic characteristics, giving equal importance to all characteristics
  2. 4. evolution of 2 species interacting with each other and reciprocally influencing each other's adaptations
  3. 6. in taxonomy, a group of similar classes; equal in the taxonomic hierarchy to a phylum
  4. 8. a non-functioning DNA segment that is similar in sequence to a functioning gene
  5. 10. similarities of biological structures that result from evolution of a common ancestor
  6. 12. condition in which a cell, a nucleus, or an organism has more than 2 sets of chromosomes
  7. 17. similarity in form or function that is not a result of of evolution from a common ancestor but is evidence of convergent evolution
