自达尔文时代以来,科学家们一直使用进化论的框架来探索地球上生命的相互联系,以及生物对不断变化的环境的适应。分子生物学的出现促进和加速了进化研究,因为它允许对遗传物质进行直接检查,最终确定选择所依据的表型。通过对微生物进化的考察,进一步深化了对进化的研究,具有种群数量多、世代时间短、DNA提取容易等特点。这项工作催生了对微生物生物地理学的研究,人们意识到群体遗传学中发展的概念可能适用于微生物基因组(Mariny等人;Mankets和Velier,)。微生物生物地理学和适应性已经在许多不同的环境中进行了研究。在这里,我们认为深层生物圈是研究进化的独特环境,并列出了可以考虑的具体因素和研究可以在哪里进行。这份出版物是美国国家科学基金会资助的暗能量生物圈调查中心(C-DEBI)进化()主题团队的成果。
Since the days of Darwin, scientists have used the framework of the theory of evolution to explore the interconnectedness of life on Earth and adaptation of organisms to the ever-changing environment. The advent of molecular biology has advanced and accelerated the study of evolution by allowing direct examination of the genetic material that ultimately determines the phenotypes upon which selection acts. The study of evolution has been furthered through examination of microbial evolution, with large population numbers, short generation times, and easily extractable DNA. Such work has spawned the study of microbial biogeography, with the realization that concepts developed in population genetics may be applicable to microbial genomes (Martiny et al.,; Manhes and Velicer,). Microbial biogeography and adaptation has been examined in many different environments. Here we argue that the deep biosphere is a unique environment for the study of evolution and list specific factors that can be considered and where the studies may be performed. This publication is the result of the NSF-funded Center for Dark Energy Biosphere Investigations (C-DEBI) theme team on Evolution ().
