- According to the theory of punctuated equilibrium, the fossil record is characterized by long periods of stability punctuated by brief periods of rapid evolution.
- The theory of punctuated equilibrium has been supported by numerous studies of the fossil record, which show that many species exhibit long periods of stability followed by rapid evolution.
