This document discusses the classification of organisms and how they are organized into a 7 level system of taxonomy. It mentions key concepts like binomial nomenclature, using Latin names for genus and species, DNA evidence, and physical traits being used by taxonomists to determine genetic and biological relationships between modern animals and their ancestors to systematically name and organize all types of organisms. A dichotomous key and field guides are tools that use the 7 level classification system.
