摘要

与基于个体实体(无论是基因、有机体还是物种)的直系和选择主义进化观点相比，共生现象向生物学家提出了非常不同的解释问题。一个关键的问题是，在特定的一代中，两个或两个以上的伴侣在密切的关系中共存，最终如何稳定到足以传递给下一代，随之而来的复杂性是如何维持的，以及这种安排在进化过程中如何影响集体的生殖适应性。在本章中，我们强调了从微生物世界收集的一些观察结果，如果在建设性中性进化的框架内观察，这些观察结果可能会揭示这个问题。

The Role of Constructive Neutral Evolution in the Development of Complexity from Symbioses: A Microbe-Centric View.

Symbiogenesis presents the biologist with very different explanatory issues compared to the lineal and selectionist view of evolution based on individual entities, whether genes, organisms or species. A key question is how the co-existence of two or more partners in close association during a given generation can ultimately be stabilized enough to be transmitted to the next, how the ensuing complexity is maintained and how this arrangement impacts the reproductive fitness of the collective over evolutionary time. In this chapter, we highlight some observations gleaned from the microbial world that could shed light on this problem if viewed within the framework of constructive neutral evolution.

期刊介绍： Results and Problems in Cell Differentiation is an up-to-date book series that presents and explores selected questions of cell and developmental biology. Each volume focuses on a single, well-defined topic. Reviews address basic questions and phenomena, but also provide concise information on the most recent advances. Together, the volumes provide a valuable overview of this exciting and dynamically expanding field.
