This course introduces students to the science and principles of biological classification. Taxonomy is the foundation of biology that allows us to name, describe, and organize all living organisms into a logical system.
You will learn how organisms are identified, named using binomial nomenclature, and grouped into hierarchical categories from Kingdom to Species. The course covers both classical taxonomy based on morphology + anatomy, and modern approaches using molecular data and phylogenetics.
Through lectures, practical activities, and quizzes on Gnomio, you’ll gain skills to classify unknown organisms, use dichotomous keys, and understand the importance of taxonomy in conservation, medicine, and research.
Learning Objectives
By the end of this course, you should be able to:
1. Define taxonomy, systematics, and classification and explain their importance.
2. Apply the rules of binomial nomenclature according to ICZN/ICN codes.
3. List and explain the 7 main taxonomic ranks: Kingdom, Phylum, Class, Order, Family, Genus, Species.
4. Construct and use dichotomous keys for identification.
5. Compare phenetic, cladistic, and evolutionary classification systems.
6. Explain how DNA/molecular data is used in modern taxonomy.
7. Identify major groups of organisms: Bacteria, Protista, Fungi, Plantae, Animalia.
