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.ConcreteEventHandler---Implementation of the concrete ChannelHandlerA5.1 Routine Inspection Items他乐呵呵地宣布，又转头问老婆子，他娘，你可有啥要说的？张老太太老脸笑得开花，连连摇头说没有啥要说的，却又望向板栗道：就是板栗，你啥时候娶媳妇回来，奶奶睡着了也笑醒了。/coldOriginally wanted to look for Naruto cartoons on Baidu, Found that all Naruto cartoons have been taken off the shelves, Naruto's Chinese website is gone.
