可是越是如此，越需要谨慎操作。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.互动爱情喜剧，围绕土星特派员土帅和火星王子火种对地球女孩陆凡的“爱情争夺”，并与生活在地球的其他外星人展开了一系列嘀笑皆非、浪漫搞笑的日常故事。 观众可在每集自由点选互动选项来决定主角的命运和剧情走向。进入美丽的海湾，登上荒无人烟的沙滩，看着眼前密布的山川植被，杨长帆大臂一挥：就叫新上海吧。14岁的印度少女尹希娅热爱唱歌，因父亲阻挠，她只能蒙面拍摄并上传自弹自唱原创歌曲的视频，孰料凭借天籁歌喉在网上一炮而红，备受争议的音乐人夏克提·库马尔（阿米尔·汗 饰）也向她抛出橄榄枝，尹希娅的生活发生了翻天覆地的变化……Firstly, the light program implementation without state mode is given:
