Until the late 1970s, there was no "Domain" as the broadest category in taxonomy. Instead, there were five kingdoms: Protista, Plantae, Fungi, Animalia, and Monera, which included all bacteria-like organisms. Researchers proposed the domains to distinguish between the bacteria-like organisms. Which information supported the domain level, and subsequent domains of Bacteria, Archaea, and Eukarya?
A. More complex emergent properties developed after organisms were originally categorized into kingdoms.
B. Organisms in the Bacteria and Archaea domains have a nucleus, whereas eukaryotes do not.
C. Cell shapes of bacteria and archaea were found to be more distinct, after microscope technology improved.
D. Differences in DNA among the existing kingdoms showed a need for a broader naming category.
E. Evolution led to new adaptations and diversity of organisms.
D. Differences in DNA among the existing kingdoms showed a need for a broader naming category.
