"Journey to the Microcosmos: How to Name a Microbe" explores how scientists identify and name microscopic organisms through taxonomy, microscopy, morphology, DNA analysis, and scientific nomenclature. Centered on Professor Bozena Zakrys’s discovery and naming of Euglena smulkowskiana—later reclassified as Phacus smulkowskianus—the video explains how microbe names can reflect physical traits, Greek and Latin roots, or honor individuals. It highlights euglenids, diatoms, tardigrades, and paramecia while showing how classification changes with new molecular evidence. The episode also emphasizes research methods, scientific literature, and the collaborative process behind species discovery. This content supports biology and life science curricula focused on microbiology, classification systems, heredity, and the practices of science. Part of the "Journey to the Microcosmos" series.
