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.　　梦想着有朝一日成为母亲那样伟大的探窟家，并解开阿比斯的谜团。陈启，你快反击。A4.1. 2.2 Cornea and sclera.旺村的元宝被某网站选中参加一档综艺节目，没想到一炮而红。他奇特的人生经历引发了广泛的社会关注，同时也引发了科学界的瞩目。在名利和欲望的驱使之下，郑正、傅负这两位机器人研究领域的科学家相继卷入元宝争夺战中。学生皇甫不惑也不甘寂寞，借机研制出机器人元宝和龙女，一步步将元宝打造成了家喻户晓的明星。但在真正一飞冲天之后，元宝、皇甫不惑等人渐渐迷失了自我。在对名利的追逐中，皇甫、元宝亲历郑正等人被名利怪兽吞噬了本心，酿成悲剧的过程，不约而同地陷入了对生命价值的反思，在充分认识到亲情、友情和爱情的可贵之后，他们最终选择放下名利，回归原本就属于他们的平凡生活。　澳大利亚SBS的犯罪喜剧《不寻常嫌犯 The Unusual Suspects》已在悉尼开拍，2021年播出。　　这部4集迷你剧以悉尼东郊的高档住宅区为背景，讲述了一条价值数百万项链的失窃，以及来自不同行业的女性聚集在一起以确保正义得到伸张。谢谢所有支持《回家》的兄弟姐妹。
