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.就比如多亏了韩信这三个字，刘邦心中已经有了想法。少女梅若华流落街头，被黄药师收为徒弟改名梅超风，与师兄弟一起在桃花岛上习武长大。黄药师发现梅超风对自己的情感已超乎师徒之情，借故离岛，两年后带回妻子冯蘅和半部《九阴真经》。尹旭也是大惊，见吴芮回来以为没事了，未曾想还有这么一出。盆儿胡同的马家四兄弟本来和别家小孩一样，幸福快乐得过着每天的生活。父母车祸身亡则终结了这平凡的日子。父亲临终前留下的遗言是：学好。四兄弟靠着救济金度日。而那句“学好”则成了老大马学武（张嘉译 饰）一直谨记的话。为了家庭和几个弟弟，他不得不放弃读书，去了工厂工作。几个兄弟里，最令人头疼的就是老二马学军（邓超 饰）。他似乎有使不完的坏点子，总爱意气用事，惹出了不少事端。家庭的困难让老大不得不把生病的老四送给他家。四兄弟在贫寒中日渐成长，各自不同的性格让他们走上了截然不同的路。他们经历不同的人生，体验时代的变迁，相同的是路上的挫折和困难，以及你是我兄弟这永不变的事实。1.
