What do gradualism and punctuated equilibrium have in common? They are both explanations of the rate of evolutionary change. They are both explanations that were put forth by Darwin. They both discredit the theory of evolution. They both utilize radioactive dating over relative dating.

They are both explanations of the rate of evolutionary change.

Explanation:

It is believed that both punctuated equilibrium and gradualism are the two ways in which the evolution of species can occur. A species can evolve by only one of these or both. Scientist believe that species with shorter evolution evolve mostly by punctuated equilibrium and those with longer evolution evolve by gradualism.

Answer;

They are both explanations of the rate of evolutionary change.

Explanation;

Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur.

-Gradualism is selection and variation that happens more gradually. Over a short period of time it is hard to notice. Small variations that fit an organism slightly better to its environment are selected for: a few more individuals with more of the helpful trait survive, and a few more with less of the helpful trait die.

-In punctuated equilibrium, change comes in spurts. There is a period of very little change, and then one or a few huge changes occur, often through mutations in the genes of a few individuals. Mutations are random changes in the DNA that are not inherited from the previous generation, but are passed on to generations that follow.

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
