Welcome to Season 2 of Bedrock! This episode introduces Season 2's subject: the Eoarchean (ee-oh-ar-key-an) chapter of Earth's history. The Eoarchean lasted from 4 to 3.6 billion years ago, from February 15 to March 19 on the Earth Calendar. In future episodes, we'll meet Earth's oldest rocks, the Man in the Moon, and a faint young sun. Since this is our first big chapter break, we'll also learn how and why geologists split time into these chapters, including one of Canada's greatest scientists: Sir William E Logan.

24: A New Dawn (Season 2 Premiere)

This podcast starts at the beginning of Earth's prehistory and works forward through time.  Bedrock will explore the first 90% of Earth’s past, a time known as the Precambrian Era.  Before humans, before dinosaurs… there was the Precambrian.
The Earth was an incredibly alien world, but not a dead one. 
Along the way, you will build a mental toolkit to see the world like a geologist. You will never look at a mountain, the moon, or pond scum in quite the same way again.

Welcome to Bedrock.
