Punctuated equilibrium is a theory in evolutionary biology that proposes a distinction between the tempo and the mode of evolution. It suggests that species experience long periods of relative morphological stability (stasis) interrupted by brief, rapid episodes of evolutionary change during speciation. The term was introduced in 1972 by Stephen Jay Gould and Niles Eldredge in response to patterns observed in the fossil record, where new forms often appear abruptly rather than as gradual transformations over long intervals.
In this view, the most significant evolutionary changes are concentrated in speciation events, often occurring in
The theory emphasizes that it is a pattern or tempo of evolution as observed in the fossil
