The Domains of Life
How the evolutionary tree branches over time forms the basis for biological classification. As our understanding of evolutionary history has improved, classification has gone from a two kingdom system (plants and animals), to five kingdoms (plant, animal, fungi, protist, and monera--the kingdom of prokaryotic cells), the classification found in many biology textbooks. Molecular techniques have now clarified the early branching of life, resulting in a useful new overview that splits life into three domains: Archaea (bacteria-like in appearance, but with different biochemistry), Bacteria, and Eucarya, the domain of organisms having cells with nuclei and membrane-bound organelles. This program introduces the three domains and focuses on the main events in the evolution of eukaryotic cells.
