Answer:
1) Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in.
2) Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

Answer:
diversifying selection
Explanation:
Diversifying selection is one in which extremes are favored and intermediate organisms are eliminated. An example of this type of selection can be seen in some African finches that are adapted to eating seeds. They vary in size (large, medium and small), but intermediate forms are rarely observed. This is because there are seeds that vary in hardness. Larger finches feed on hard seeds, and smaller finches feed on soft seeds. This type of selection results in large genetic variation in the population. This is because there are seeds that vary in hardness. Larger finches feed on hard seeds, and smaller finches feed on soft seeds. This type of selection results in large genetic variation in the population.
