I don't know the precise term, but mammals are a separate group
(family?). There are many different species of mammals.

No, no, no! Disnosaurs and mammals are both vertebrates and have
evolved from a common ancestor. But mammals did *NOT* evolve from

In Eiffel we would have ;-)  :


    class DINOSAUR is

    inherit
         BACKBONE
    features
       ...
    end;


         and

    class MAMMAL is

    inherit
        BACKBONE
    features
        ...
    end;
