种内基因进化不能总是用一棵分叉树来表示。相反，种群谱系通常是多分支的，后代基因与持久的祖先共存，重组事件产生网状关系。虽然传统的系统发育方法假定有分叉的树，但最近已经开发了几种联网方法来估计考虑到这些种群水平现象的种内系谱。
Intraspecific gene evolution cannot always be represented by a bifurcating tree. Rather, population genealogies are often multifurcated, descendant genes coexist with persistent ancestors and recombination events produce reticulate relationships. Whereas tradition al phylogenetic methods assume bifurcating trees, several networking approaches have recently been developed to estimate intraspecific genealogies that take into account these population-level phenomena.
