This describes the theory of punctuated equilibriumdeveloped by Stephen Jay Gould and Niles Eldridge.
Gould's greatest contribution to science was the theory of punctuated equilibrium which he developed with Niles Eldredge in 1972. The theory proposes that most evolution is marked by long periods of evolutionary stability, which is punctuated by rare instances ofbranching evolution. The theory was contrasted against phyletic gradualism, the popular idea that evolutionary change is marked by a pattern of smooth and continuous change in the fossil record.
This concept is known as Punctuated Equilibrium. A theory developed by Steven J Gould and Niles Eldridge.

Stephen Jay Gould was an influential evolutionary biologist known for his work on punctuated equilibrium, which proposed that evolution is not always a slow, gradual process but can occur in rapid bursts of change followed by long periods of stability. He also contributed to the field of evolutionary developmental biology (evo-devo) and was a strong advocate for the idea that science and religion could coexist harmoniously.

When Darwin first published his theories on evolution by natural selection, he envisaged evolution as a slow, steady process, with little variation in the rate of change. Later discoveries showed that this process was unlikely to be so slow and steady as was thought earlier; that in stead certain conditions enabled lifeforms to change rapidly, to develop significantly different morphologies in the course of less than 10.000 generations even. The first scientists to formulate such a model were S.J. Gould and N. Eldridge, and their model was called 'punctuated equilibrium'. To summarize: the significant difference between Darwin's gradualism and Gould's punctuated equilibrium is the variation in the rate of change.
