- Historic Period: 4,000 to 3,000 BCE – Various Civilizations
Classification has been both a gift and a curse for our world. The initial concept such as making specific classifications for plants and animals made a lot of sense. It allowed us to keep track and know what possible risks we faced. For example, if a specific plant was poisonous then we’d want to steer clear. If specific animals might look bad but are usually not going to attack humans, we needed to know this too. Most animals and plants were often classified by their characteristics, such as their appearance. Later on, we’d add more to the classification concept and go into far more depth.
