Taxonomy - Classification

Taxonomic classification is the grouping together of different organisms into different taxa (taxonomic categories), such as family, genus, and species. In the time of Linneaus (mid-1700s), taxonomists and naturalists did not generally acknowledge that all species have evolutionary affinities to other species. Thus, early classification systems were artificial, in that they did not represent the lines of evolutionary descent. Most early taxonomists classified species according to their overall similarity because they thought this revealed the divine origin of nature.
