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.

WebbTo establish ancestor-descendent relationships we need to identify a suitable outgroup and then root the tree on the branch separating the outgroup from the remainder of the tree (the ingroup). We can specify the root before the building the tree to produce a rooted tree, or we can specify the root after the tree is built to change an unrooted tree to a rooted tree. Webbbiology.
