Time Line of Earth’s History

You are going to construct a time line of the major events of Earth’s history concerning the evolution of life. On this timeline, you should list the events that we discuss in class (for example, the age of Earth, the Iron Catastrophe, first evidence of life, Great Oxygenation Event, Cretaceous-Tertiary extinction event, etc) AS WELL AS information about each of these events. This timeline will serve as a very helpful study guide for you, so starting it now will count as study practice for your tests!
