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.
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.

There is still not consensus within the scientific community on which system to use (most modern textbooks refer to the 5 or 6 kingdom system).
