Molecular evidence indicating less than 50% shared genes was the basis for:

A) dividing the prokaryotes into two domains, Bacteria and Archaea.
B) separating the kingdom Protista from the kingdom Animalia.
C) including algae and slime molds in the kingdom Protista.
D) the separation of eukaryotes and prokaryotes.
E) placing fungi in a separate kingdom.

Molecular Evidence

Information derived from molecular biology, such as DNA sequences, that is used to support hypotheses in fields like evolutionary biology and phylogenetics.

Shared Genes

Genetic elements that are common or identical among different organisms, indicating a degree of genetic relatedness or evolutionary history.

Prokaryotes

Prokaryotes are unicellular organisms lacking a distinct nucleus and membrane-bound organelles, including bacteria and archaea, characterized by their simple cellular structure.

  • Recognize the significance of molecular evidence in the classification and evolutionary study of organisms.

Final Answer :
A
Explanation :
Molecular evidence, particularly the analysis of ribosomal RNA sequences, showed that prokaryotes are divided into two fundamentally different groups, leading to the establishment of the domains Bacteria and Archaea. This was a significant revision of the tree of life, recognizing the deep evolutionary divide between these two groups.
