Webb5 aug. 2015 · Specifically, by establishing a root we allow for the identification of an ingroup clade and outgroup taxa set with respect to a node in reference tree. This allows us, for example, to distinguish between grades and clades through the unions and intersections of ingroup and outgroup taxon sets; this is not possible when working … 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…
