  7. - Domains and Kingdoms Three Domains of Life • Domain is the highest or broadest level of classification • There are three types of Domains: Modern Bacteria Ancient Bacteria

  8. The Eight levels of Classification • Domain: * Largest level * Not related at all • Kingdom: • Phylum: • Class: • Order: • Family: • Genus: • Species: * Smallest number of members * Closely related * Can reproduce

  12. Question Answer Review What is a Domain? The highest or broadest level of classification Bacteria Archae Eukarya What are the 3 domains? The science of naming, describing and classifying organisms What is Taxonomy?

  13. HOMEWORK • Can you come up with your own acronym for the eight levels of classification?
