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.

The answer is more contentious than you would think. Today, we visit one of the most debated locations in the show: a small island off the Greenland shore named Akilia. Everything about these rocks has been contested, and we'll meet three scientists who form cornerstones of the debates. Extra Credit: Watch something on an old CRT TV, or count tree rings in a stump.","meta_description":"How old is the oldest slice of Earth's seafloor?
