Summary Introduction
To determine:
The possible evolutionary consequences to other species due to the extinction of one species
Introduction:
There are two types of extinction events which occur in the ecosystem. The background extinction results due to the normal evolutionary process. Mass extinction of species occurs due to the disappearance of a large number of species in a relatively short time.

- Using Index Fossils Problem How can fossils be used to determine the relative ages of rock layers? Introduction It is easy to compare the ages of fossils found in sedimentary rocks at one location. Fossils found in an upper rock layer will be younger than fossils found in a lower layer, unless the layers have been overturned. It is not as easy to compare the ages of fossils found in rocks at different locations. Scientists use index fossils to determine the relative ages of rock layers. Scientists use radiometric dating to find the actual age of rocks and fossils. In this lab, you will work with drawings of rock layers from different locations. Each layer will contain at least two fossils. Using the fossils as clues, you will organize the layers from oldest to youngest.
