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.该剧描述了维京人鼎盛时期的故事，他们在当时的北欧地区处于统治地位，因为喜好海上劫掠并不断对外扩张，被人们冠以「北欧海盗」的别号。该剧将侧重于描写维京人的生活、贸易、探索及对外侵袭。Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.Unexpectedly, the ship did not sink, because there was nothing in the warehouse and there was not much water in the water warehouse.
