Welcome to Part One of a two part series of Earth's Life History! Part One has been titled "The Beginning" as it deals with the beginning of not only the Earth, but life itself. We start with the Precambrian Era, and then delve into the Paleozoic Era, discussing each of the Periods that make up the Paleozoic Era as well. At the side, you see the "Table of Contents" with a set of red time periods. They are in order and all that you have to do is click on each time to find a page about it. When you finish them all, just go to the "Links" and click on "The Middle and then the End" as this will be part two of the series.
