"Uncovering Earth's Evolution: 565-Million-Year-Old Fossils Reveal Key Moment in Life's History"

Researchers have precisely dated some of the oldest fossils of complex multicellular life to 565 million years ago, marking a pivotal moment in Earth's history when the seas began teeming with new lifeforms after 4 billion years of containing only single-celled microbes. The fossils, found in Wales, resemble modern-day marine species and provide insight into the response of life to the thaw out from a global glaciation, highlighting the deep connection between geological processes and biology. This discovery sheds light on Earth's biological history and the evolution of life.
