Multiple Choice

Which of the following is not part of the punctuated equilibrium model?

A) There is a period of no change interrupted by speciation.
B) Transitional fossils are less likely to be found.
C) It is difficult to determine when speciation occurred.
D) It often involves an isolated subpopulation.
E) Speciation often occurs rapidly. In the punctuated equilibrium model, speciation occurs rapidly after long periods of little to no change, making transitional fossils rare. Rapid speciation events can occur from isolated populations, but once fossils of the new species are discovered, it is relatively straightforward to determine the point in time at which the speciation event occurred.
