"Life on Earth May Have Begun in Saudi Arabia 3.48 Billion Years Ago, Study Finds"
Scientists have discovered living stromatolites on Sheybarah Island in Saudi Arabia's Red Sea, marking the first such find in the Middle East. These ancient microbial structures, formed by cyanobacteria, offer insights into Earth's early life and environmental conditions 3.48 billion years ago. The study, published in Geology, highlights the significance of stromatolites in the Great Oxygenation Event and their potential as biosignatures for extraterrestrial life.
