Issues with common names and indicating relationships. 2. The Linnaean System Developed by Carl Linnaeus based on characteristics and structure. Hierarchical classification: Kingdom, Phylum, Class, Order, Family, Genus, Species. 3. The Binomial Naming System Using Genus and Species for unique, two-part Latin names (e.g., Homo sapiens). 4. Developments in Classification Impact of improved microscopes and understanding internal structures. 5. The Three-Domain System Developed by Carl Woese based on RNA sequence analysis. Domains: Archaea, Bacteria, Eukaryota (added above Kingdom level). Characteristics of each domain. 6. Evolutionary Trees How they show evolutionary relationships between species. Understanding common ancestors. Basis in structural comparison, DNA analysis, and fossil records. 7. Remembering the Order Mnemonic for the classification hierarchy. ** CHAPTERS ** 0:00 Introduction: Why Classify Organisms? 0:45 Linnaean System 1:02 Kingdom to Species 1:34 The Binomial Naming System 2:35 Three-Domain System 3:56 Understanding Evolutionary Trees 5:12 Mnemonic for Classification Order ** PLAYLISTS **    • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
