Question
Write in brief about progressive changes in animal classification.
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.

If body of any animal is cut through ______ axis of body, it may or may not produce two equal halves. Depending upon this property, there are different types of animal bodies. In the case of ______ body, there is no any such imaginary axis of the body through which we can get two equal halves. For example Amoeba, ______ some sponges. In radial symmetry type of body, if imaginary cut passes through central axis but any plane of body, it gives two ______ halves. For example Starfish. In case of this animal, there are five different planes passing through ______ axis of body through which we can get two equal halves. In Bilateral symmetry type of body, there is only one such imaginary axis of body through which we can get two equal halves. For example: ______ fishes, frog, birds, human, etc.
