Punctuated equilibrium is a theory proposed by Niles Eldredge and Stephen Jay Gould in the 1970s. It suggests that evolution occurs in fits and starts, with long periods of stasis (little or no change) punctuated by brief periods of rapid evolution. This theory suggests that evolution is not a slow, steady process, but instead occurs in bursts ...
