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.远远的对轰从不是西班牙无敌舰队的风格。一天，年轻有为的男老师恒俊调到她们班当副班主任。在亲密无间的接触中，仙花渐渐爱上了这位风流倜傥的年轻老师。转眼就要毕业，仙花大胆地向老师表白深藏的爱意，不料掀起滔天波澜。一夜之间，怀疑、非议、排挤、打击接踵而来……考虑到年龄差距、师生关系等诸多的问题，已有心上人的恒俊一口回绝了一片痴心的仙花。面对满城风雨，为得到自己憧憬已久的爱情，在父亲的支持与鼓励下，仙花义无返顾地踏上了艰辛的寻爱之旅……如今正是上天考验你们的时候，若是一蹶不振，说明你们还差一把火候。
