Saltationism is "any of several theories holding that the evolution of species proceeds in major steps by the abrupt transformation of an ancestral species into a descendant species of a different type, rather than by the gradual accumulation of small changes."[1] An example of saltationism in evolutionary thought was Goldschmidt's hopeful monster theory. *Punctuated equilibrium originally incorporated saltationism but later was declared merely complementary to phyletic gradualism[2][3]
