Biology Dictionary
 Definition: Two anatomical structures or behavioral traits within different organisms which originated from a structure or trait of their common ancestral organism. The structures or traits in their current forms may not necessarily perform the same functions in each organism, nor perform the functions it did in the common ancestor. They may even have become completely unused and therefore vestigial. Compare analogy.
