HBH 47: Life on the Installment Plan Redux

Continuing with the origins of everything that is, I present the history of planet Earth, from its birth to the age of mammals. <br /><br />Included:<br /><ul><li>How old is the earth?</li><li>What are the oldest rocks ever found?</li><li>How old is life itself?</li><li>When did multicellular organisms arise?</li><li>When did life leave the sea for land?</li><li>What percentage of species has survived until the current time?</li><li>What were the 5 biggest mass extrinction events in history?</li></ul>And much more...information that sounds, admittedly, tedious, but only because it is. But! Can you truly know about yourself without knowing about the universe, solar system, and planet that are a part of you?<br /><br />
