Via MJ Banias in thedebrief.org: Scientists have identified living stromatolites on Saudi Arabia’s Sheybarah Island in the Red Sea, marking the first discovery of living shallow-marine stromatolites in the Middle East. The discovery raises significant questions related to how and where life first originated on planet Earth. Published in the journal Geology, the study explores these ancient microbial structures and offers a unique glimpse into Earth’s early life and the environmental conditions that prevailed billions of years ago.
