Aristotle - Philosophy and Ethics

Science

Biology

Aristotle's research in the field of biology were mainly about the natural environment of the island Lesbos, where he observed the surrounding seas and also neighbouring areas. He wrote down detailed descriptions of catfish, electric fish, cephalopods and sepia.

Aristotle also created a classification of animals in today's called vertebrates and invertebrates and live-bearing and egg-bearing. He also believed that creatures were arranged in a scale of perfection from plants up to man, the so called Great Chain of Being.
