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.男子摆手一笑：等病好了，你我再喝个痛快《呼叫助产士》是英国广播公司（BBC）出品的一部古装电视剧。它由海蒂·托马斯基于珍妮佛·沃斯的回忆录编写，Neal Street Productions打造，讲述了20世纪50年代伦敦东区助产士们的工作、生活与情感。3.
