在生物系统中，进化的创新不仅可以从父母传给后代（即垂直传播），而且可以在个体之间“水平”传播，这些个体可能有关系，也可能没有关系。这一点在细菌中表现得最为明显，新的生态特征可以通过水平基因转移（HGT）在物种内部和物种之间迅速传播。这一重要的进化过程主要是可移动遗传因子（MGE）传染性传播的副产品。我们将讨论有利于通过HGT传播性状的生态条件，共享性状的进化和社会后果，以及HGT是如何通过细菌和MGE之间的内在冲突形成的。
n In biological systems, evolutionary innovations can spread not only fromparent to offspring (i.e. vertical transmission), but also 'horizontally' between individuals, who may or may not be related. Nowhere is this more apparent than in bacteria, where novel ecological traits can spread rapidly within and between species through horizontal gene transfer (HGT). This important evolutionary process is predominantly a by-product of the infectious spread ofmobile genetic elements (MGEs). We will discuss the ecological conditions that favour the spread of traits by HGT, the evolutionary and social consequences of sharing traits, andhowHGTis shaped by inherent conflicts between bacteria and MGEs.This article is part of the themed issue 'Process and pattern in innovations from cells to societies'.
