What is the difference between modern classification system and Aristotle and Linnaeus?

The modern classification system, based on phylogenetics, categorizes organisms based on evolutionary relationships and genetic information, reflecting their common ancestry. In contrast, Aristotle's classification was primarily based on observable characteristics, such as habitat and morphology, leading to a simplistic grouping of organisms. Linnaeus improved upon this by introducing a hierarchical system and binomial nomenclature, but it still focused mainly on physical traits rather than evolutionary lineage. Overall, modern taxonomy integrates genetic data and evolutionary history, providing a more comprehensive understanding of biodiversity.
