Classification and Taxonomy Concepts

The video tutorial covers the basics of taxonomy, the science of classifying living things. It introduces Carl Linnaeus, the father of taxonomy, and explains the modern classification system, which includes three domains: Eukarya, Bacteria, and Archaea. The tutorial details the classification hierarchy from domain to species and introduces phylogenetics, which uses molecular biology to study organism relationships. It also includes practical exercises using a dichotomous key and a classification chart to help students prepare for their lab exam.
