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.Round 3: 1-2,在两个赛季中，拉里继续追求他的激情写作，尽管一个新的浪漫的方式获得；莱斯利决定去探索自己的创业精神；玛歌是男孩疯狂和让人彻底不适合玩；和Gerry，谁喜欢动物的人，非常高兴，当他发现一只水獭是住在家里。丹尼尔莱派恩加入投本赛季Hugh Jarvis–英国绅士集的视线路易莎。但是，在她试图嫁给斯文的失败后，路易莎会为她生命中的新男人做好准备吗？（以上来自软件翻译）影片讲述了一名杀手Asher（朗·普尔曼 饰）在执行最后一个任务时，遇到了一个让他生活颠覆的女人（法米克·詹森 饰）。　　来自日本的白川凛突然介入，几番交手中，白琉璃轻敌被俘，却意外发现了铜镜的秘密。面对白川凛的步步紧逼，无心决定主动出击。他借助小丁猫和顾基的黑帮势力，设下局中局，毁掉了白川凛手中的铜镜。此举本可置他于死地，岂料顾基却暗中助他逃脱，希望借此换得烟土代理人的位子。你现在是齐王了，既然为诸侯，论功行赏，赏赐对齐国有功的臣子将领也是名正言顺的。本片讲述了两对情侣的爱情故事。
