关于开展元古宙重大生命演化事件研究的建议

九十年代以来，随着生物地层学研究的深入发展，我国在元古宙生物演化的研究中，取得了一个接一个的重大进展。其中除了在南方扬子地区约600Ma晚震旦世地层中的许多发现（如庙河生物群、瓮安生物群和高家山生物群等）外，还在北方元古宙的地层中，特别是在约18亿年前的常州沟组中，不仅早已发现了迄今最古老的单细胞浮游真核生物，而且新发现了具细胞组织的宏观多细胞生物及有性生殖结构。所有这些不仅为进一步深入研究元古宙生命演化规律奠定了全新的基础，而且还表明对这一领域的研究我国具有十分优越的地质条件，因此，如果能进一步加大支持力度的话，在我国关于元古宙生物演化的研究和理论完全有可能在短期内取得全面突破，我国的科学家将可能在该研究领域取得更加重大的成果，为人类的科学事业做出更加重要的贡献。

THE SUGGESTION TO START THE RESEARCH ON THE SIGNIFICANT EVOLUTIONAL EVENTS OF THE PROTEROZOIC LIFE

Since 90' s, with the deepening research for the Precambrian biostratigraphy, theresearchers in China have rnade coniderable headway in the study on the evoution of theProterocoic life. Of them, except for the rnany progresses from the Neoproterozoic Sinian System(such as the discovery of the Miaohe Biora, the Wun' an Biota and the Gaojiashan Biota), notonly the oklest record for the unicellular planktoulc eukariotes, but also both the megascopicfossils with multicellular tissues and the sexual reproductive organs have been found from theProtcorozoic rocks, especially in the 1 800-millionyear-old Changzhugou botbo in the NorthChina. All of these data no only lay a new foundation for further deepening the research on theeVdstion of the Proterozoic life, but also indicate that there are very superior conditions for theresearch in this field in China. If the dynarnics of support could, therefore, be fUrther increaed,the research for the evolution of the Proterosoic life will possibly be made comrehensivebreakthrough, the mor significant achievements will be obtained in this field in short time-
