Answer: The earlier proposed 3-kingdom system has been expanded to 5-kingdom system
Explanation:
While taxonomy originated, a 3-kingdom system was proposed which include
- ARCHAEA,
- BACTERIA and
- EUKARYA.
However, as scientific discovery advanced, more organisms were discovered and evolutionary patterns were understood; thus leading to the presently used 5-kingdom system in taxonomy.
The 5-kingdom system include:
- MONERA
- PROTISTA
- FUNGI
- PLANTAE
- ANIMALIA
The said expansion made some organisms to be moved from one kingdom or category to another.
