Apr 14, 2022 by News Staff

In 2017, paleontologists found 3.75- to 4.28-billion-year-old microscopic filaments and tubes, which appeared to have been made by iron-loving bacteria, in rocks from the Nuvvuagittuq Supracrustal Belt in Québec, Canada. However, not all scientists agreed that these structures — dating about 300 million years earlier than what is more commonly accepted as the first sign of ancient life — were of biological origin. Now, after extensive...
