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.黄豆鼓着腮帮子，翻眼瞪了板栗表哥好一会，却没跟往常那样跳脚大嚷，而是用手肘撑着桌面，小拳头顶着下巴，陷入沉思。1997年周六9点档播出的连续剧《我们的勇气～未满都市》于邪魔外道而言，他们是令人欲除之而后快的眼中钉肉中刺　　G型神探一直以来为Metro市里最出色的警探之一，直到邪恶的克劳博士(鲁伯特-艾弗莱特饰)出现为止。克劳博士设计陷害G型神探，让他被误以为是盗取Metro市立银行数百万元的嫌疑犯，害得他不但被摘下警徽同时还名誉扫地。G型神探一定得将邪恶的克劳博士绳之以法，洗刷自己的冤情，恢复神探的美名。Aunt Wang stamped her feet in regret: "I would have bought the genuine product if I had known it."
