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.Write according to your own thinking, finish and then take out magazines to compare and revise, and correct your own version.我愛冰冰Show《美丽新天地》讲述的是香港人来上海创业奋斗的故事。已经成功摆脱花瓶形象的范冰冰在剧中扮演性格复杂的上海女子程琳，与张智霖、杨恭如、邓健泓及高云翔共同演绎了一段微妙暧昧而又曲折动人的“五角恋”。　　尹施允饰演陆东植，他是底层基金经理，作为证券公司的小职员就职，几年来一直负责各种杂务。性格很胆小也很心软，因此总是被人利用，他无法拒绝各种不合情理的要求，组长只有火气没地方撒的时候才会想起他来，他的同期同事都已经晋升，连刚进公司的菜鸟都看不起他。而他却从来没有生过气，是名副其实的烂好人里的烂好人。　　子建痴心鸯鸯，鸯鸯苦等申然，申然难忘子欣，子欣待嫁启宏。五个人，四段感情，最爱是谁？This is because some Western politicians, including the United States, Britain and France, have repeatedly accused the media of carrying out news propaganda without any evidence.
