From: Exploring phylogenetic hypotheses via Gibbs sampling on evolutionary networks
Three different models of four sequences of two sites each, TT, TG, GG, and GT, from four taxa A, B, C, and D, respectively. a A data-display network that accommodates the two conflicting splits AB |CD and BC |AD. b An evolutionary network that explicitly models a reticulation event involving taxon B. c A tree model that would fit the data if, for example, a recurrent mutation occurred at the second site
