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.在英国大学做客座演讲后，布伦南博士和布斯被要求调查一名年轻女子的死亡。 她的父亲是一位在英国工作的富有的美国商人。他们的同伴协助他们进行调查。 同时，安吉拉（Angela）的丈夫到达杰斐逊（Jeffersonian），他对与她离婚不感兴趣。After getting the event handler, add it and the response to the queue respectively.
