Original Caption: Aristotle.
Although he is commonly known as an Ancient Greekphilosopher, Aristotle is also considered by many to be the first true scientist due to his dedication to studying and making sense of observable facts. He noticed that dolphins have lungs, do not lay eggs, and produce milk for their young. He concluded that they were not fish and grouped them together with other aquaticmammals, specifically whales and porpoises, in a biological classification called cetacean. From studying rocks and land, he concluded that the Earth changes dramatically over time. He noted that rivers and seas dry up in some areas while the land becomes covered by water in other areas. He also believed the human lifespan was too short to see these great changes. In addition to biology and geology, he also made contributions to physics, astronomy, and meteorology. Just imagine what he would think of our world today!
