Fossil evidence indicates that some dinosaurs had feathers. If birds are indeed descended from those feathered dinosaurs, feathers are what kind of character? See Concept 26.3 (Page 557) polyphyletic character analogous character cladistic character shared derived character shared ancestral character

shared ancestral character

It is evident from the fossils that were discovered by the scientist and biologist that some of the dinosaurs have feathers and wings. Birds also have feathers and wings.

So it is believed that birds have descended from those feathered dinosaurs.

And it is proved that these feathers are a shared ancestral character descended from the dinosaurs.

Shared ancestral character are those character that is ancestral or similar to a specific species like feathers.
