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.英布不及时接管江东也就罢了，彭城危急也不前来救援，这样的人留着说不定哪一天会出乱子。This.command = command;Metallized hole2015年是梵高的125年诞辰，为了纪念梵高，英国著名的电影工作室BreakThru Films(曾获得奥斯卡奖)和Trademark Films从2012年开始筹拍一部名叫《Loving Vincent》的动画电影，通过动画师手绘的120幅梵高画作，试图探索梵高的精神世界与死亡之谜。英雄，是踩在另一位准英雄的尸体上成为英雄的。本片讲述俄罗斯空军研制成功了“苏-35”型列战斗机，它具有最先进的技术和最卓越的功能，引起了国内外广泛的关注，其中也包括了恐怖分子，本片的主人公是一位出色的战斗机飞行员，他驾驶着最新型的苏式战斗机与他们展开战斗，为俄罗斯空军立下了汗马功劳……
