Taxonomy: Life's Filing System - Crash Course Biology

The video explores the Dewey Decimal System of evolution, focusing on taxonomy's role in categorizing life. It highlights Carl Linnaeus' contributions, including binomial nomenclature, and explains the modern taxonomic system, including domains and kingdoms. The video concludes with an example of classifying a cat using this system.
