Binomial nomenclature? No, it’s not a rare disease, it’s the two-name identification system for plants and animals, developed by Carolus Linnaeus hundreds of years ago! In this BrainPOP UK movie on classification, Tim and Moby explain why all organisms need to have long and sometimes unpronounceable names. In this educational, animated movie, you’ll learn about the major subcategories, or taxa, that biologists use to classify organisms. These include: domain, kingdom, phylum, class, order, family, genus, and species. And you’ll see how different animal species are ordered in the tree of life, including all of the taxa they belong to. This is not classified information—in fact, it’s pretty classy!
