Answer:
Molecular Evidence has recently made it necessary to assign the prokaryotes to either of two different domains.
Explanation:
- There was an OLD 5 classification system :
- Monera
- Protists
- Plants
- Fungi
2. NEW 3 domain system reflects :
- A greater understanding of evolution
- Molecular evidence
Thus, the new domain includes :
- Prokaryote : Bacteria
- Prokaryote : Achaebacteria
3. Eukaryotes :
- Protists
- Plants
- Fungi
- Animals
