About: Evolutionary fauna

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The concept of the three great evolutionary faunas of marine animals from the Cambrian to the present (that is, the entire Phanerozoic) was introduced by Jack Sepkoski in 1981 using factor analysis of the fossil record. An evolutionary fauna typically displays an increase in biodiversity following a logistic curve followed by extinctions (although the Modern Fauna has not yet exhibited the diminishing part of the curve).

  • 演化动物群（英語：Evolutionary fauna）是由美国芝加哥大学古生物学家杰克·塞科斯基于1981年提出的概念，其利用化石记录的因子分析将自寒武纪至今（即整个显生宙）以来发展出的所有生物大致划分为三大动物演化群系。在展示演化动物群的发展过程中，通常以逻辑曲线的升降方式来显示出演化过程中生物多样性的增加和灭绝事件所导致的减少（人类所属的现代演化动物群目前尚未表现出该曲线的递减部分）。 (zh)
