The second classification principle of organisms is the lineage classification principle aiming at establishing evolutionary lineage. 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.这个中年人穿过老板娘，在陈启身前停了下来。吴凌珑想不通，杨寿全想不通，翘儿更加想不通。吕雉已经表示过了，只要韩信肯肯出兵，现在的汉太子，未来也是实际上的汉王刘盈会向齐国称臣。在场的所有人都有一种不可思议的感觉。电视剧《狼殿下》，讲述了后梁奎州城郡主摘星与生长于狼群中的少年狼仔相识，错别八年后相遇，狼仔已成狠厉的渤王，两人需在复仇、危机中为爱力战天命的故事。Integral Import
