Correct option is D
The correct answer is (D) Carl Woese
Explanation:
• Carl Woese proposed the three-domain system of taxonomy in 1977.
• He divided the kingdom Monera into two distinct domains: Archaebacteria (Archaea) and Eubacteria (Bacteria) based on 16S ribosomal RNA (rRNA) sequences.
Information Booster:
• Archaebacteria are ancient bacteria known as extremophiles because they can survive in highly harsh conditions (e.g., hot springs, highly saline environments).
• This classification fundamentally changed our understanding of the tree of life.
Additional Knowledge:
• Charles Darwin (Option A): Famous for the theory of evolution by natural selection.
• Robert Whittaker (Option B): Proposed the Five-Kingdom classification (Monera, Protista, Fungi, Plantae, Animalia) in 1969.
• Ernst Haeckel (Option C): Proposed the Three-Kingdom classification by introducing Protista.
