The classification method following this principle is called lineage classification. The representative of pedigree classification is "branch systematics". It advocates that the branches in evolution should be taken as the criteria for identifying and distinguishing classification units and the basis for determining the pedigree relationship of each classification unit. The so-called co-ancestral proximity (similar to a group of people being a grandfather) is used to measure the genetic relationship between different taxa and determine their position in the pedigree. The classification system finally established is an evolutionary pedigree reflecting the history of phylogeny, which is a deeper description of biological relationship. In other words, the basic principle of pedigree classification is that the classification system conforms to the evolutionary pedigree. Pedigree classification is only applicable to organisms and cannot be used for abiotic classification.
