Who was the 1st person to classify living things?

The first person to classify living things was the ancient Greek philosopher Aristotle. He categorized organisms based on their characteristics, such as their habitat and physical traits. Aristotle's system laid the groundwork for later classification systems, including the more formal taxonomy developed by Carl Linnaeus in the 18th century. Linnaeus is often credited with establishing the modern system of naming and classifying organisms using binomial nomenclature.
