This text may be correct, but it is not decipherable to anyone not very intimate with cladistics. It seriously need improvement. Petter Bøckman (talk)...

in many explanations of symplesiomorphy is that three groups need to be considered, since to call a character a symplesiomorphy of two groups we have to...

(UTC) On further perusal I see the equivalent is plesiomorphy and symplesiomorphy. Lavateraguy (talk) 18:22, 17 December 2018 (UTC) Those are more specific...

basal Dinosauromorpha as well — and these characters could all be symplesiomorphies.--MWAK (talk) 07:37, 8 June 2008 (UTC) That was more than enlighting...

morphological similarity is irrelevant, since this may be due to symplesiomorphies, which are valueless in determining relationships. (1) is now accepted...

Bennetittale, a group of plants morphologically close to Cycad (probable symplesiomorphy), but clealy divergent. If you want a fossil illustaion of Cycad's...

characters are unenlagiine? Can they be interpreted otherwise (e.g. symplesiomorphies)? Or does the "Dakoptaraptor" material indeed contain unenlagiine...

the particular ancestor being considered. (It is an apex trait.) A symplesiomorphy is an apex trait that is 1. shared by (some not necessarily all) members...

Neighbor-Joining, group by overall similarity, and treat both synapomorphies and symplesiomorphies as evidence of grouping, The resulting diagrams are phenograms, not...

distinctive features are removed, i.e. they are defined by shared symplesiomorphies (for botanists, consider the old Liliaceae), or they are created by...

November 2009 (UTC) There is a discussion of apomorphy, synapomorphy, and symplesiomorphy, all terms that are defined within the field of cladistics. Unless...

cladistics can better deal with homoplasies as it isn't as easily fooled by symplesiomorphy. Yes, taxon and outgroup choice can strongly influence the results...

synapomorphies was held to be philosophically superior to the use of symplesiomorphies (not to be confused with symplesiosaurs, which were the first aquatic...

characteristics". One of these, "brow horns longer" (i.e. than nasal horn), is a symplesiomorphy shared with T. horridus (so it isn't supposed to mean that the horns...
