What does the term punctuated equilibria describe?

Question

Accepted Answer

Hi everyone. Welcome back. Let's look at our next answer choice. It says. Which of the following does not describe punctuated equilibrium. So let's recall from our content videos what is function equally punctuated equilibrium and that is the notion that changes that result in speciation can occur at rapid bursts over a period of time followed by stasis very little morphological change. So with that in mind knowing we're looking for an incorrect statement that does not describe punctuated equilibrium. Let's look at our answer choices. Choice A says changes can occur at rapid bursts over a period of time. That is true and therefore not our answer choice B says there will be periods of stability. Yes that is true. In between the births of change we have these stable periods. That's the equilibrium part of punctuated equilibrium choice C says speciation can occur and this is correct to eliminate choice C. Um These rapid bursts of change that happened very quickly often lead to speciation. And finally we're on the choice D evolutionary change happens at constant rates. This is incorrect. So which of the following does not describe punctuated equilibrium choice D evolutionary change happens at constant rates. Punctuated equilibrium course, observes these rapid bursts with long periods of nothing much. See you in the next video
