Horizontal gene and genome transfer forces us to recognize that life evolves by fusion as well as bifurcation of lineages, and necessitates the expansion of traditional views of evolution. This chapter reviews the role that horizontal gene transfer (HGT) may play in integrating selection at the gene, species, and community levels. Additionally, we provide an overview of the structure and content of this book, which reflects current thought in the dynamic field of HGT research.
水平基因和基因组转移迫使我们认识到,生命通过谱系的融合以及分支进行演化,这就需要扩展传统的进化观点。本章回顾了水平基因转移(HGT)在整合基因、物种和群落水平的选择中可能发挥的作用。此外,我们还概述了本书的结构和内容,它反映了HGT研究动态领域的当前思想。
