(a) With each generation, most ducks had about the same amount of webbing on their feet as their parents. One of the basic ideas in the theory of evolution is that the more characteristics that are shared by two species: A. the more recently they shared a common ancestor. Progressive changes in the fossil record are evidence for evolution because: they show inheritance of characteristics acquired within a generation, There is substantial evidence that descended from a hooved, terrestrial ancestor.
