进化过程如杂交、横向基因转移和重组都是塑造基因和基因组结构的关键因素。然而，由于这些过程并不总是最好的表示树，现在有相当大的兴趣，而不是使用更一般的网络。例如，在最近的研究中已经表明，网络可以用于提供重组事件数量的下限，也可以用于提供在一组分子序列的进化历史中发生的横向基因转移数量的下限。在本文中，我们描述了一些相关的界限，结果合并对树到网络的理论性能。
Evolutionary processes such as hybridisation, lateral gene transfer, and recombination are all key factors in shaping the structure of genes and genomes. However, since such processes are not always best represented by trees, there is now considerable interest in using more general networks instead. For example, in recent studies it has been shown that networks can be used to provide lower bounds on the number of recombination events and also for the number of lateral gene transfers that took place in the evolutionary history of a set of molecular sequences. In this paper we describe the theoretical performance of some related bounds that result when merging pairs of trees into networks.
