The basic intuition behind the idea of policy punctuations is that the political agenda is stable for extended periods of time but is also subject to occasional changes that are large in magnitude (Baumgartner & Jones, 1993, 2009).

Punctuated equilibrium. A theory that states species stay the same for a long time, then new species evolve suddenly due to global changes and mass extinction. Coordinated stasis. A pattern where most species appear at about the same time. Mass extinction.

Punctuated Equilibrium is a theory originating in paleobiology which has been adopted by management researchers to explain organizational change. In this theory, episodes of radical change are preceded and followed by longer periods of relative stability.

Genetic equilibrium is the condition of an allele or genotype in a gene pool (such as a population) where the frequency does not change from generation to generation. Genetic equilibrium describes a theoretical state that is the basis for determining whether and in what ways populations may deviate from it.

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. Therefore mutation, gene flow, small population, nonrandom mating, and natural selection will disrupt the equilibrium.

What is genetic equilibrium? List the five conditions that can disturb genetic equilibrium and cause evolution to occur. Non random mating, small population size, immigration or emigration, mutations, and natural selection.
