1. Customer trust is stronger;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.未来某时，一种丑陋凶恶、仿佛来自地狱的怪物肆虐人间，大肆屠杀人类。某小镇在怪物的荼毒下宛如一座死城，生存者战战兢兢，惶恐度日。爱莉安娜·格兰德登上伦敦的舞台，奉上“甜到翻世界巡回演唱会”，并分享了她在排练和巡演中的幕后生活。电影《说好不分手》，由傅靖生、费明导演执导，剧中电视台著名足球解说员滕远峰突然接到法院离婚判决，百思不得其解，故事从离婚后展开，随着滕远峰对事件内在原因的探究，个中道理越来越明晰。现实与回忆交替，使剧中人和观众一起沉浸在情感的惊涛骇浪之中。最后，滕把第三者告上法庭。亦有同名电视剧《说好不分手》，由顾晶导演执导，孙淳 、陈小艺 主演，演绎一出都市爱情故事。36岁的肿瘤科医生、医学博士冷云既知性聪慧，又美丽优雅。"You have to believe grandma.
