If a characteristic is found in the ancestor of a group, it is considered a shared ancestral character because all of the organisms in the taxon or clade have that trait.

Only some of the organisms in image have this trait, and to those that do, it is called a shared derived character because this trait derived at some point but does not include all of the ancestors in the tree.Lizards, rabbits, and humans all descend from a common ancestor that had an amniotic egg.
