Scientists have discovered fossils that reveal the Earth's transition from simple animals to complex creatures, earlier than previously thought. The findings provide new insights into the evolution of life on Earth. Researchers believe this transition occurred millions of years ago, paving the way for the diverse range of species we see today.

Newly discovered fossils have given scientists their first real glimpse of when Earth made a crucial transition from plants and unrecognizably simple animals to the complex creatures that took over the world and would eventually lead to us. And it happened millions of years earlier than researchers thought, as FRANCE 24's Caitlin Brown explains in this report.
