There are various scientists who 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 red blood cells, whether they live on land, air, or water. 

• Carolous Linneaus (1707-1778): Also known as the father of taxonomy, he classified living things into two kingdoms- Plantae and Animalia.
