- 1. the branch of biology concerned with reconstructing phylogenies and with naming and classifying species
- 5. the basic unit of taxonomic classification, consisting of a population or series of populations of closely related and similar organisms. In sexually reproducing organisms, a species can be defined as a population or series of populations of organisms that interbreed freely with one another under natural conditions but that do not interbreed with members of other species
- 8. the name of an organism formed from the two smallest major taxonomic categories - the genus and the species
- 9. the taxonomic category contained within a class and consisting of related families
- 11. the broadest category for classifying organisms ; organisms are classified into three domains - Bacteria, Archaea, and Eukarya
- 13. one of the eight major categories based on evolutionary relationships, each family contains a number of genus
- 14. the evolutionary history of a group of species
- 15. one of life's three domains ; consists of all eukaryotes (plants, animals, fungi, protists)

- 2. the taxonomic category composed of related orders. Closely related classes form a division or phylum
- 3. the taxonomic category contained within a family and consisting of very close related species
- 4. the total number of species within an ecosystem and the resulting complexity of interactions among them
- 6. the process of determining the order of nucleotides in a DNA molecule
- 7. the second broadest taxonomic category, contained within a domain and constituting of related phyla or divisions
- 10. one of life's three domains ; consists of prokaryotes that are only distantly related to members of the domain Archaea
- 12. one of life's three domains ; consists of prokaryotes that are only distantly related to members of the domain bacteria
- 14. the taxonomic category of animals and animal-like protists that is contained within a kingdom and consists of related classes
