Origination of a lineage through the partial merging of two ancestor lineages, leading to relationships better described by a phylogenetic network than a bifurcating tree.
These results indicate that phylogenetic relationships within recently duplicated human DNA can be rapidly disrupted by reticulateevolution.

This discordance was consistent with the reticulateevolution of nuclear genes supporting the hypothesis that D. g. mendotae represents a case of homoploid hybrid speciation.
