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.Article 14 Confronted situations本剧根据李世民几个儿子争夺储位的真实历史事件，艺术地编织了他废立皇储的曲折故事，通过庶出皇子李恪、李佑等人与长孙一脉的三个嫡出皇子李承乾、李泰、李治间的储位之争，布置了大量悬念，矛盾冲突惊心动魄，扣人心弦。国家重任，民族未来的选择，让李世民经历了深重的情感炼狱，他长期在封建君王的责任和父子之情间徘徊，不断遭受着心理的折磨。不过，理智最终战胜情感，通过长期考察，他选定了聪明仁爱的皇子李治作为自己的接班人，扶助他继承了帝位，使得贞观的政治路线得到延续……The most disgusting thing in the world is久违的吃货五郎又回来了！个体杂货商店的老板井之头五郎（松重丰 Yutaka Matsushige 饰）将在这个夏天不仅继续为千奇百怪的客人搜寻各种稀奇古怪的玩意儿，更将在工作间隙再次带领大家深入日本的大街小巷饱尝各色令人垂涎欲滴的美食。从重磅出击的奶油水果三明治早餐，到浓郁醇香的黑咖啡，到油光锃亮的鳗鱼配上晶莹剔透的米饭，再到百吃不厌的中华料理，五郎虽然还是一个人吃饭，可是却将那种一个人的忘我和悠然发挥得更加淋漓尽致。大快朵颐后的满足不禁不断让人感受到生活中简单的美好，更让我们看到其实并不“孤独”的民间美食家井之头五郎。《巨人》是韩国SBS电视台2010年播出的创社20年台庆剧，由刘仁植导演，张英哲编剧，李凡秀、郑宝石领衔主演。是一部以上世纪60~70年代首尔江南大开发为题材的时代剧，以上世纪60年代的首尔为舞台，讲述了三兄妹在首尔城市大开发中的成长故事。
