Fossils from China Reveal Complex Life Evolved Earlier Than Thought
Newly discovered fossils from southwestern China suggest that complex life evolved millions of years earlier than previously believed. The fossils, found at the Jiangchuan Biota site in Yunnan province, date back to the Ediacaran period (635 million to 542 million years ago). This discovery challenges the long-held belief that complex animal life emerged during the Cambrian period, known for its explosion of fauna diversity. The fossils include goblet-shaped sea jelly relatives, wormlike animals, and segmented sea creatures, preserved in exquisite detail. The findings indicate that complex animal life, including potential ancestors of vertebrates, existed at least 4 million years before the Cambrian. The research, published in the journal Science, provides new insights into the evolution of life on Earth.
