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.漂亮而天真的雏妓科莱特答应照顾她朋友的小孩比利。而她自己则需要一个孩子来令到前夫回心转意。这样一来，她就可以“一石二鸟”了：为比利找个合适的“爸爸”，再把他摆脱掉。她是个充满爱心的女人，某天深夜她接到一个电话，一个陌生男子要她帮忙找到他儿子并带给他。然而当科莱特找到那个叫比利的男孩，并准备将他带给那个男人时，她却发现这个即将进入成人期，十分叛逆的男孩对她的善意并不领情。带着一种朦胧的渴望和对未来的怀疑，比利处处和科莱特作对，而科莱特则必需想办法克服种种障碍，还要尽最大的努力避免比利成为孤儿，她和比利之间的关系有所发展。在两人磕磕碰碰一路前进。好在有蒲俊才能足够，为人机警稳重，定不会辜负自己的期望。见尹旭骑着马彻底消失在黑夜之中，刘邦头也不回道：你说他的会可信吗？不用说这话自然是问张良张子房的。影片由三个小段落组成，每一个小段落自成一章，之间有着微弱的联系。4.
