Punctuated equilibrium refers to the idea that speciation can occur rapidly in bursts, followed by long periods of little change. This fits with the hypothesis that a single gene change may have jump-started speciation in Mimulus. Pre-zygotic and post-zygotic barriers to reproduction typically involve multiple genetic changes over a longer period of time, while gradualism implies a slow and steady accumulation of genetic changes. Adaptive radiation occurs when a single ancestral species gives rise to many closely related species over a relatively short period of time, but there is not enough information provided in the experiment to support this explanation.
