The theory of punctuated equilibrium is based on positive evidence, including extensive studies of living and extinct species groups (Eldredge and Gould 1972). ... The theory of punctuated equilibrium was proposed ad hoc to explain away the embarrassing gaps in the fossil record.

The "punctuated equilibrium" theory of Niles Eldredge and Stephen Jay Gould was proposed as a criticism of the traditional Darwinian theory of evolution.

But in 1972, evolutionary scientists Stephen Jay Gould and Niles Eldredge proposed another explanation, which they called "punctuated equilibrium." That is, species are generally stable, changing little for millions of years.

In the 70s or 80s (can't remember), Steven J. Gould and Niles Eldridge (sp?) came up with the theory of punctuated equilibrium, which says that evolution is mostly stasis, with brief periods of explosive speciation.
