Rooting phylogenetic trees with distant outgroups: a case study …

The chosen outgroup is hypothesized to be less closely related to the ingroup than the ingroup is related to itself. The evolutionary conclusion from these relationships is that the outgroup species has a common ancestor with the ingroup that is older than the common ancestor of the ingroup. Choice of outgroup can change the topology of a phylogeny. Therefore, phylogeneticists typically use more than one outgroup in cladistic analysis. The use of multiple outgroups is preferable be… Webb21 okt. 2024 · The ingroup is the group of taxa that is investigated for determining evolutionary relationships.
