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.

To get back to the point, At this time, I saw Zhang Xiaobo's expression was in high spirits. He was obviously very proud and relieved of his hatred for beating up the "killer bee" with the flickering armor-piercing bullet. Associated with his slightly melancholy expression just now, it was obviously not this one that made him melancholy. I was not the kind of person who liked to expose people's scars, but for work reasons, I still had to ask:
