In the 18th century, Carl Linnaeus published a system for classifying living things, which has been developed into the modern classification system.

Taxonomy's first father was the philosopher Aristotle (384-322 BC), sometimes called the father of science.. It was Aristotle who first introduced the two key concepts of taxonomy as we practice it today: classification of oranisms by type and binomial definition. Aristotle was the first to attempt to classify all the kinds of animals in his History of Animals (Historia Animalium in Latin). He grouped the types of creatures according to their similarities: animals with blood and animals without blood, animals that live on water and animals that live on land.
