  "summary": "Phylogenetic trees have long been a powerful model of the evolutionary history. However, key processes in speciation, such as introgression and hybridization are difficult to depict with strictly binary trees alone, even with modern discordance metrics and post-hoc tests. Phylogenetic networks offer an intuitive way to estimate and interpret these reticulate events, as conflicting signal from…",
