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.江美珊和田川从高三补习班开始就是好朋友，各种阴差阳错让他们一直没能将心中的感情说出口，所以五年来一直维持着好朋友的关系。终于有一天两人勇敢表达了心中爱意，从好朋友变成了恋人。恋爱后的江美珊和田川，与其他小情侣一样，也遇到了各种各样的问题：女朋友的时保联、前男友的电话、前女友的挑逗，他们该如何面对这些问题呢？　　Nikita（李美琪 Maggie Q 饰）因抢劫商铺拒捕失手杀死一名警察，而被送到了女子监狱。后被代号为“Division”的秘密政府组织解救。组织伪造了Nikita的死亡证明，并赋予她机会开始新的生活——把她训练成一名间谍和顶级杀手，让她效忠自己的国家。可就在组织杀死了她的爱人后看清了一切真相逃离组织。躲藏三年之后她重出江湖，决定不惜一切代价揭发组织的阴谋和秘密。另一面，她安插了内应Alex（琳德西·冯塞卡 Lyndsy Fonseca 饰）进入组织内部做卧底。而Michael（夏恩·韦斯特 Shane West 饰）是追捕尼基塔小组的负责人，却与她有一种惺惺相惜的感情......Suddenly the captain told us to hide.
