Now I have chosen the case of the whale and porpoise group because they offer so extreme an example of profound modification of structure in adaptation to changed conditions of life.
The theory of evolution by natural selection supposes that hereditary characters admit of being slowly modified wherever their modification will render an organism better suited to a change in its conditions of life.
Let us, then, observe the evidence we have of such adaptive modifications of structure, in cases where the need of such modificationis apparent.
