Question

What two kingdoms was kingdom Monera separated into?

Answer 1

Monera was recognised as a kingdom first by Copeland. The kingdom included all prokaryotic organisms. Monera remained a part of 5 kingdom system introduced by Whittaker (1969).

Explanation:

Later Carl Woese floated an idea of three domain system of classification in biology. He decided to divide cellular forms of life in three domains: Archaea, Bacteria and Eukarya (all eukaryotic organisms).

This automatically divided the prokaryotic group Monera in Archaea and Bacteria.

1. Archaea is most ancient evolutionary group which includes prokaryotic organisms living generally in extreme environments.
2. Bacteria is a diversified prokaryotic group with some advanced features.

After this recommendations put forward by Carl Woese, biologists often recognise a 6 kingdom classification system:

Archaea
Bacteria
Protista
Mycota(Fungi)
Plantae
Animalia.
