Name, for ten points, this theory of evolution developed by Niles Eldredge and Stephen Jay Gould.
Developed in 1972 after a study of the speciation of West Indian land snails, this model has been used variously to explain the development of a biosphere as well as the study of morphological evolution. It proposes that evolution of species is "jerky," with most changes occurring during speciation events, with little change over the rest of the duration of a species.
