Scientists Dig Up Earth’s Oldest Fossil (Video)
Scientists say they discovered the world’s oldest fossils — dating back 3.77 billion years. The research team found the fossilized microorganisms in quartz layers of some of the world’s oldest rock.
This discovery comes just a few months after another team of scientists announced it had found the world’s oldest fossils in Greenland. But those fossils date back only 3.7 billion years.
Both research teams agree these discoveries could help in the search for life on other planets. If life existed on Earth in one of its most radical states, it might be able to survive the extreme conditions of other planets in our universe.
