The Tree of Life in microbiology is a branching diagram representing evolutionary relationships among organisms across three domains: Bacteria, Archaea, and Eukarya. It reflects genetic changes over time, aids in species identification, and informs conservation biology. This framework is crucial for understanding microbial diversity, evolution, and practical applications in disease control and bioengineering.
