Explanation / Answer

answer :Punctuated equilibrium The "punctuated equilibrium" theory is proposedby Niles Eldredge and Stephen Jay Gould Eldredge and Gould observed that evolution tends tohappen in fits and starts, sometimes moving very fast, sometimesmoving very slowly or not at all. On the other hand, typical variations tend to be small.Therefore, Darwin saw evolution as a slow, continuous process,without sudden jumps. However, if you study the fossils oforganisms found in subsequent geological layers, you will see longintervals in which nothing changed ("equilibrium"), "punctuated" byshort, revolutionary transitions, in which species became extinctand replaced by wholly new forms.
