Biological classification is the process of grouping and organizing living organisms based on their similarities, differences, and evolutionary relationships. Systems of Classification 1.⁠ ⁠Artificial System Based on one or few characters Example: classification based on habitat or color Proposed by Aristotle Does not show evolutionary relationships 2. Natural System Based on many characters Uses morphology, anatomy, physiology Proposed by Bentham and Hooker ✔ More accurate than artificial system 3.⁠ ⁠Phylogenetic System Based on evolutionary relationships Uses fossils, genetics, and molecular data Proposed by Ernst Haeckel ✔ Most accepted modern system Carolus Linnaeus classified the living organisms into two kingdoms – ANIMALS and PLANT Ernst Haeckel proposed a third kingdom of life –PROTISTA Herbert F. Copeland proposed the fourth kingdom MONERA. The Five-Kingdom Classification system was proposed by R. H. Whittaker (1969). The five kingdoms are: Monera – Unicellular prokaryotes (bacteria, cyanobacteria) Protista – Unicellular eukaryotes (Amoeba, Euglena) Fungi – Eukaryotic, non-photosynthetic organisms (yeast, mushrooms) Plantae – Multicellular, photosynthetic organisms (plants) Animalia – Multicellular, heterotrophic organisms (animals) Join this channel to get access to perks:    / @catalystcentreofexcellence
