Who discovered the theory of human classification?

The theory of human classification, often associated with the biological taxonomy of humans, was significantly developed by Carl Linnaeus in the 18th century. He introduced the binomial nomenclature system, categorizing humans as Homo sapiens. Later, various anthropologists and geneticists have expanded upon this framework, exploring human diversity and classification in more depth. However, Linnaeus is credited with laying the foundational principles of human classification in the scientific context.
