ORIGINS OF LIFE AND EVOLUTION OF BIOSPHERES

The origin and early evolution of life is an inseparable part of the discipline of Astrobiology. The journal Origins of Life and Evolution of Biospheres places special importance on this interconnection. While any scientific study which contributes to our understanding of the origins, evolution and distribution of life in the Universe is suitable for inclusion in the journal, some examples of important areas of interest are: prebiotic chemistry and the nature of Earth's early environment, self-replicating and self-organizing systems, the theory of the RNA world and of other possible precursor systems, and the problem of the origin of the genetic code. Early evolution of life - as revealed by elucidation of biochemical pathways, molecular phylogeny, the study of Precambrian sediments and fossils and of major innovations in microbial evolution - forms a second focus. The journal presents experimental papers, theoretical articles and authoritative literature reviews.

生命的起源和早期进化是天体生物学不可分割的一部分。《生命起源与生物圈进化》杂志特别重视这种相互联系。任何有助于我们理解宇宙中生命起源、进化和分布的科学研究都适合刊登在《自然》杂志上。一些重要领域的例子包括:生命起源前的化学和地球早期环境的性质，自我复制和自我组织系统，RNA世界和其他可能的前体系统的理论，以及遗传密码的起源问题。生命的早期进化——通过阐明生物化学途径、分子系统学、前寒武纪沉积物和化石的研究以及微生物进化方面的重大创新揭示出来——形成了第二个重点。该期刊发表实验论文、理论文章和权威文献综述。
