我们描述了一些新的和最近的结果，允许分析和表示的网状进化的非树网络。特别是，我们（1）提出了一个简单的结果，表明，尽管存在网状结构，总是有一个明确的基础树，对应于那些部分的生活，没有一个历史的网状结构;（2）描述和应用新的理论，以确定最小数量的杂交事件所需的解释冲突的基因树;（3）提出了一种新的判定任意根网络能否由同时发生的网状事件实现的算法。我们举例说明这些结果。
We describe some new and recent results that allow for the analysis and representation of reticulate evolution by nontree networks. In particular, we (1) present a simple result to show that, despite the presence of reticulation, there is always a well-defined underlying tree that corresponds to those parts of life that do not have a history of reticulation; (2) describe and apply new theory for determining the smallest number of hybridization events required to explain conflicting gene trees; and (3) present a new algorithm to determine whether an arbitrary rooted network can be realized by contemporaneous reticulation events. We illustrate these results with examples.
