The court jester hypothesis builds upon the punctuated equilibrium theory of Stephen Gould ( 1972 ) by providing a primary mechanism for it.

Some of these scientists charged that his theories, like punctuated equilibrium, were so malleable and difficult to pin down that they were essentially untestable.

Biologists favoring the idea of punctuated equilibrium have argued that there are natural constraints that may keep a species unaltered for millions of years.

Punctuated gradualism is considered to be a variation of these models, lying somewhere in between the phyletic gradualism model and the punctuated equilibrium model.

As time went on Gould moved away from wedding punctuated equilibrium to allopatric speciation, particularly as evidence accumulated in support of other modes of speciation.

Dawkins also emphasizes that punctuated equilibrium has been " oversold by some journalists ", but partly due to Eldredge and Gould's " later writings ".

The other was punctuated equilibrium, drawn from evolutionary biology and used by Thurow to illustrate rapid and fundamental economic change punctuating the normally slow evolutionary process.
48.
Then in 1972, the two proposed the theory of punctuated equilibrium, which suggested that both the sudden appearances and lack of change were, in fact, real.

Many credit punctuated equilibrium with promoting the flowering of the field of macroevolution, in which researchers study large-scale evolutionary changes, often in a geological time frame.

But in 1972, the two proposed the theory of punctuated equilibrium, a revolutionary suggestion that the sudden appearances and lack of change were, in fact, real.
