What is the model in of evolution in which periods of rapid change occur is called?

Punctuated equilibrium is the model of evolution in which periods of rapid change occur interspersed with long periods of stability. This theory suggests that species evolve quickly in short bursts of rapid change followed by extended periods of little or no change.

According to the theory of punctuated equilibrium at what rate does speciation occur?

Punctuated equilibrium theory suggests that speciation occurs relatively rapidly, in geologically short periods of time, followed by long periods of stasis where little evolutionary change occurs. This contrasts with the gradualism theory, which proposes that evolution happens at a constant and slow rate over long periods of time.


Why do girls have monthly periods?

Girls get periods to prepare their bodies to have a baby when they are older. The blood comes from inside the uterus, in which the wall of the uterus sheds a fluid containing blood that isn't needed. It is needed when you get pregnant. That's why you miss periods if you are pregnant.
