Cradles of the Earth: Greenland's Isua Greenstone Belt and the Dawn of Life

from Intellectually Curious · host Mike Breault

We travel to the Isua Greenstone Belt in southwest Greenland to read Earth's oldest rocks (3.7–3.8 billion years). This episode digs into what these rocks reveal about early oceans and crust, weighs the plate tectonics versus heat-pipe debate, and surveys the first signatures of life—from light carbon isotopes to possible stromatolites—and what these clues imply for life on other worlds.Note:  This podcast was AI-generated, and sometimes AI can make mistakes.  Please double-check any critical information.Sponsored by Embersilk LLC
