Module 2: Classification - Unveiling Life's Organization

Biological classification is a systematic approach that organizes life into hierarchies based on shared characteristics, revealing evolutionary relationships among organisms. This module explores various criteria for classification, such as cellular structure, ecological niche, and genetic data, and emphasizes the dynamic nature of classification as a tool for understanding life's complex organization. Through model organisms, learners appreciate the applications of classification in biological research and discovery.
