Solution
There are various scientists which have contributed to biological classification and based on their observations we have the current system of classification:
- Aristotle (384-322 BC): Also known as the father of classification, he classified animals on the basis of two points: presence or absence of blood, whether they live on land, air, or water.
- Carolus Linnaeus (1707-1778): Also known as the father of taxonomy, he classified living things into two kingdoms- Plantae and Animalia.
- Ernst Haeckel (1834-1919): He proposed the three kingdom classifications- Plantae, Animalia, and Protista.
- Robert Whittaker (1920-1980): He gave the five-kingdom classification- Monera, Protista, Fungi, Plantae, and Animalia.
- Carl Woese (1928-2012): He gave the classification where he classified all the organisms into three categories- Eukarya domain, Bacteria domain, and Archae domain.
