A shared character that is to a specific taxon is a shared ancestral character. In comparison with a shared derived character, it is the difference broadly between the character arising more recently (shared derived, that is, both within and defining a taxon) or instead less recently (shared ancestral).
In phylogenetics, a plesiomorphy, symplesiomorphy or symplesiomorphic character is an ancestral character (trait state) shared by two or more taxa - but also with other taxa linked earlier in the clade (that is, having an earlier last common ancestor, with them, than theirs).. In this situation, the fact that the taxa under consideration share the trait state may hint strongly that they are ...
An ancestral trait is a trait shared by a group of organisms as a result of descent from a common ancestor in history. ... put anything on that character in your shared bank (3) Go to your ...
In phylogenetics, apomorphy and synapomorphy refer to derived characters of a clade: characters or traits that are derived from ancestral characters over evolutionary history. An apomorphy is a character that is different from the form found in an ancestor, i.e., an innovation, that sets the clade apart from other clades.
An ancestral character is shared with the species ancestral to more than one group: it can lead to different groups being classified together. A shared derived character is shared by the ancestral species and a single group: it is the only reliable guide to inferring phylogeny.

Specifically, we are interested in shared derived characters. A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals.

Use of shared ancestral characters results in paraphyletic groups: a monophyletic group that includes the ancestor and some but not all of its descendants. This creates a Grade: a group defined by a combination of shared ancestral & derived characters
