    Stephen Jay Gould
    His famous theory is Punctuated Equilibrium, which pertains to the theory of evolution with respect to the rate of speciation.

    I don't know how your first link applies to all this other than it suggesting evolution in general.

    The original image would just demonstrate systematics as a way of representing species relatedness, i.e., an evolutionary "tree."

    The diagram shows just a conceptual inheritance tree, with succession of species (or other levels) going upward on the vertical axis and morphology (that is to say features of individual species) spread out horizontally. By itself it doesn't represent a theory; it's just a schematic for representing things.
