## Resource

The Jiangchuan Biota fossil site in China is transforming our view of early life. Dating to the Ediacaran Period, over 700 specimens reveal advanced traits like bilateral symmetry and segmentation—well before the Cambrian explosion. Featuring strange worm-like creatures and early animal forms preserved in fine carbon films, the discovery suggests that complex life evolved gradually, not suddenly—pushing back the timeline of animal evolution.
