How we came to be: Fossils rewrite origins of life on earth

Newly discovered fossils have pushed back the timeline for when Earth transitioned from simple plants and basic animals to the complex creatures that would eventually lead to humans—occurring millions of years earlier than previously believed. The finding represents the first substantial fossil evidence scientists have obtained of this critical evolutionary turning point in Earth's history. The discovery reshapes our understanding of how life evolved and diversified on the planet, suggesting the emergence of complex animal life happened at an accelerated pace compared to earlier models. Researchers now have direct paleontological evidence to fill a gap that had long remained murky in the fossil record. This revised timeline has implications for understanding how quickly life can evolve and adapt once conditions permit increased complexity.
