User: analogous Weegy: Analogous structures pertain to the various structures in different species having the same appearance, structure or function but have evolved separately, thus do not share common ancestor. User: vestigial Weegy: Vestigial structure is a structure in an organism that has lost all or most of its original function in the course of evolution, such as human appendixes.
