Ch-02: Biodiversity
This chapter explores the vast diversity of life on Earth. It defines biodiversity and classification, highlighting the advantages of organizing living organisms. Students trace the history of classification from Aristotle to Linnaeus and learn the modern three-domain system
(Archaea, Bacteria, Eukarya). The text explains taxonomic ranks (from Domain to Species) and the rules of binomial nomenclature. A key discussion focuses on the unique challenges of classifying viruses, which straddle the line between living and non-living entities.
