摘  要:
635~551兆年的地史时期,新元古代陡山沱期的扬子地台发生了真核生物进化与辐射的事件。对陡山沱期的生物群从研究进展、构成、地层学、分子古生物学和诱因等方面进行探讨,系统地概括了中国南方陡山沱期生物事件的整体面貌。新生态系统在冰期后开始构建,不同地点出现相同的化石分子说明可能存在生物的扩散与空间竞争;分子生物学的证据也表明陡山沱期是真核生物演化的重要阶段。

摘  要:
During the 635-551 Ma,evolution and radiation of eukaryotes had occurred on the Yangtze platform during the Neoproterozoic Doushantuo Period. The biota of the Doushantuo period was discussed in many fields,consists of the advances in the study,construction,stratigraphy,molecular paleontology and predisposition etc. And the entire features of biological events of the Doushantuo period in southern China were summarized. After glacial epoch,new ecosystem was established,and many different localities had the identical fossils. The results showed that the proliferation and spatial competition may be occurred to biota. And the evidences of molecular paleontology indicate that the Doushantuo period was the important stage of eukaryote's evolution history.
