Explanation:

In studying Earth's history of climate scientists take help of available rocks and body parts of aquatic animals. As rocks are the most eventful findings on the earth's surface which has come across million of years and witnessed several changes. These study if changes in rock is called paleontology.

Question 1. When the mean value of variation is selected against, ____ selection results.

Marysya12 [62]

Question 2:
slow, steady evolution of a small isolated population

This evolutionary theory suggests that a species slowly and continuously evolved over a long period of time. This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms.
