Macro-taxonomy involves study of homology, analogy, affinities, systematic status and phylogeny.
The term macro taxonomy is made up of two terms. Macro taxonomy is defined as "the branch of taxonomy that deals with the categorization or grouping of organisms above the species level on a large scale."
Macro is derived from the Greek term Makros, which means huge, taxis, which means arrangement, and nomus, which means rules.
