A trait that arose in the ancestor of a phylogenetic group and is present (sometimes in modified form) in all of its members, thus helping to delimit and identify that group. Also called a shared derived trait.
An ancestral trait is a genetic similarity passed down to subsequent generations, such as eye and skin color. Male pattern baldness and flushed cheeks are also considered ancestral traits. Ancestral traits are DNA structures that tell people about the origins of their ancestors. They also explain why family members may look alike.

In phylogenetics, a primitive (or ancestral) character, trait, or feature of a lineage or taxon is one that is inherited from the common ancestor of a clade (or clade group) and has undergone little change since. Conversely, a trait that appears within the clade group (that is, is present in any subgroup within the clade but not all) is called advanced or derived.

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.
A derived trait is a trait that the current organism has, but the previous one did not have. An ancestral trait is a trait that you, and your ancestors had. A vestigial structure is a structure that had some sort of use in your ancestor, but none in your current body.
plesiomorphy (ancestral trait) An evolutionary trait that is homologous within a particular group of organisms but is not unique to members of that group (compare apomorphy) and therefore cannot be used as a diagnostic or defining character for the group.
