2. Taxonomy is the part of science that focuses on naming and classifying or grouping organisms. Swedish naturalist, Carl Linnaeus, developed the current hierarchical classification system of taxonomic classification in the 1700s. This classification is hierarchical so one class has many orders, and one order has many families. Birds can be classified under the Linnaean hierarchical taxonomy as “Aves”. In one system of classification, Aves has 23 orders, one of which is the order Ciconiiformes, which holds six families within it.
