Foundational Biology: Classifying Life on Earth

Understanding the immense diversity of life requires a systematic approach to organization. Biological classification provides the essential framework for studying every organism on the planet. By the end of this course, you will have mastered the core principles of taxonomy, including nomenclature, hierarchical ranks, and the characteristics defining major domains and kingdoms. You will be able to interpret modern classification systems and apply this knowledge to biological studies. What you'll learn: * Understand the historical development of taxonomy, including the Linnaean system of binomial nomenclature. * Master the seven main hierarchical ranks used to classify organisms, from domain to species. * Learn the defining characteristics of the three domains (Archaea, Bacteria, Eukaryota) and the five kingdoms of life. * Apply systematic rules for naming and classifying diverse organisms using written descriptions. * Practice interpreting phylogenetic trees and cladograms used in modern molecular classification. The course begins with core terminology and the history of classification before diving into the specific rules of nomenclature and hierarchy. Subsequent sections detail the characteristics of the major domains and kingdoms, concluding with an introduction to how molecular data influences current taxonomic models. This course is designed specifically for absolute beginners with no prior knowledge of biology or taxonomy. No prerequisites are required, only a willingness to read and practice.
