Ingroup cladogram

Webb28 feb. 1993 · After parsimony is measured locally among the outgroups to estimate ancestral states, parsimony is measured locally within the ingroup, given the ancestral states, to find the ingroup cladogram. This two-step procedure is shown to find the ingroup cladograms that are most parsimonious globally; that is, most parsimonious … Webbthe assumption of ingroup monophyly makes it axiomatic that the ingroup does not include the root. In summary, the parsimony method with the fewest a priori assumptions and the greatest likelihood of finding the globally most-parsimonious ingroup cladogram in-volves simultaneous unconstrained anal-ysis of the ingroup and the outgroups to

WebbTo other biologists, “cladogram” suggests that the lengths of the branches in the diagram are arbitrary, while in a “phylogeny,” the branch lengths indicate the amount of character change. The words “phylogram” and “dendrogram” are also sometimes used to mean the same sort of thing with slight variations.
