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.Context.method ();/doom4、六月雪 7集 窦娥－傅娟 东门笑－谢绍光刘大脑袋发展得特别好，事业很顺畅，这样一个女秘书可能是看上了，于是刘大脑袋就心猿意马了。皮校长与谢兰生了个儿子，取名志高。谢广坤高兴坏了摆了一片酒席，全村人都去贺喜。刘能找到赵四，希望赵四配合他，去谢广坤家白吃白喝，把当年谢广坤在他们家白吃白喝的事找回来。赵四为了玉田的未来的儿子没同意。刘能觉得自己去，但是刘英娘坚决反对，并且说，如果刘能去干白吃的事，她也不去了。刘能只好拿钱去随礼。赵四看见刘能来了，感觉刘能如果不随礼实在没有面子，就悄悄告诉刘英去劝劝刘能，不料这话被谢大脚听到，告诉了谢广坤。长贵一直在镇上齐镇长办公室等齐镇长，齐镇长没回来，打电话也不接。长贵很着急。谢大脚打电话让长贵抓紧时间回来，马上开席了。王云也给刘大脑袋打电话，让刘大脑袋过来，刘大脑袋答应马上。王云在身边预留了一个座位。谢广坤正得意地抱着皮校长的儿子到处跑，百忙中，跑到门口拦住刘能，说刘能不随礼就不让他进门。刘能把礼拿出来，谢广坤有些意外，反而被刘能取笑一顿。谢广坤当众表示，刘能的随礼钱不要，可以白吃。少女时代泰妍将担任预计今年上半年播出的女团回归大战Mnet《Queendom 2》的主持人。我练了《易筋经》和《神剑诀》。
