World’s Oldest Fossils Aren’t Actually Fossils, New Research Suggests
Two years ago, researchers from the University of Wollongong in Australia shook the science world by claiming to have discovered 3.7 billion-year-old fossils in a rock formation in Greenland, a finding that pushed back the origin of life on Earth by 200 million years. New research is now casting doubt on this discovery, with scientists saying the rock structures are of non-biological origin.
In the original 2016 study, geologist Allen Nutman and colleagues identified cone-like structures, ranging between 1 and 4 centimeters in length, in 3.7-billion-year-old rock found in the Isua formation in southwest Greenland.
