One of the earliest known classification systems was created by Aristotle, a Greek philosopher who lived from 384–322 BC. He classified more than 500 species of animals in a book, separating them on the basis of if they had blood (vertebrates) or no blood (invertebrates). His pupil, Theophrastus, wrote a similar piece of work classifying plants.

Many years later, the Swedish botanist Carl Linnaeus (1707–1778) described a 2-kingdom system of living things: animalia and plantae (he also described a third, non-living kingdom of minerals). Linnaeus devised a nested hierarchical system for classifying groups of organisms based on their similarities. He had five levels of classification: Kingdom, Class, Order, Genera and Species.
Carl Linnaeus many years later, created 5 levels of classification. List them below in order. The first one is done for you.

This system has been modified over the years, with additional levels of classification added. There have since been 3, 4, 5, 6, 7 and 8 kingdom systems proposed.
