Colorado Sandstones Reveal Earth's Ancient Ice Age
A study from the University of Colorado Boulder provides strong evidence supporting the Snowball Earth theory, suggesting Earth was once entirely frozen, even at the equator, between 720 and 635 million years ago. Researchers analyzed ancient rock formations in Colorado, finding that glaciers likely covered the planet, impacting early life and possibly facilitating the evolution of multicellular organisms. The study highlights the importance of geological research in understanding Earth's climatic history and its influence on life's evolution.
