Use of the term punctuated equilibrium appeals to Darwinian scientific authority; Brock is appealing more to the authority of Newton, as if the policymaking process can be described according to precise mathematical rules, as a physical system might be.
The observation of stasis in the fossil record and the theory of punctuated equilibrium were the main focus of the deliberations.
The gist of punctuated equilibrium is that most evolutionary change takes place in relatively brief spurts, when new species diverge from old ones, and that species otherwise tend to remain unchanged throughout long stretches of time.

In her subsequent explanation, she uses the timely analogy of modern biologists debating the relative roles of gradualism and punctuated equilibrium or the relative frequencies of different modes of speciation without questioning whether evolution itself occurs.
