In the 18th century, Carl Linnaeus published a system for classifying living things, which has been developed into the modern classification system. Recently the classification system of life was changed to include not five but six kingdoms, as well as three domains. Earlier classification attempts were based mostly on structural features. Classification of many species, old and new, continues to be hotly disputed as scientists find new information or interpret facts in new ways. Now, DNA technology has allowed scientists to re-examine the relationships between organisms to refine the classification system. The Kingdom Monera in the old classification system included all bacteria. What two kingdoms now encompass prokaryotic organisms? A) Bacteria and Archaea B) Eubacteria and Archaea C) Bacteria and Archaebacteria D) Eubacteria and Archaebacteria
