Until now, scientists broadly accepted complex life forms first emerged on Earth around 635 million years ago (Ediacaran period). But an international team of paleontologists from Cardiff University, the Université de Toulouse, the Université de Poitiers and China Nonferrous Metals (Guilin) Geology and Mining Co. Ltd discovered evidence of a much earlier ecosystem in the Franceville basin near Gabon on the Atlantic coast of Central Africa over 1.5...
