7. Classification

Aristotle noticed that certain plants and animals seemed to fall under certain categories. He used his observations to begin classifying animals and plants and was the first person to do so. When it came to animals, he divided them into two main categories, which were those with red blood, and those without.

Within those classifications were another five classifications in each group, with another level of classification being the species. His classifications are very similar to those that we use today, although whether or not they have red blood has been replaced with whether or not they are vertebrates.
