现在人们普遍认为，系统发育网络比树木更能代表某些物种的进化历史。例如，多倍体通常被认为是通过杂交和复制产生的，这一过程可能不能最好地表示为分叉的物种形成事件。基于对多倍体多标记树相关集合的了解，我们提出了一个展示该树的系统发育网络的规范构建。此外，我们证明了所得到的网络在某种定义良好的意义上是一个具有这种性质的最小网络。
It is now quite well accepted that the evolutionary past of certain species is better represented by phylogenetic networks as opposed to trees. For example, polyploids are typically thought to have resulted through hybridization and duplication, processes that are probably not best represented as bifurcating speciation events. Based on the knowledge of a multi-labelled tree relating collection of polyploids, we present a canonical construction of a phylogenetic network that exhibits the tree. In addition, we prove that the resulting network is in some well-defined sense a minimal network having this property.
