Study Suggests Complex Life Began 2.1 Billion Years Ago, Not 635 Million. A recent study led by Cardiff University suggests that complex life on Earth may have begun much earlier than previously thought around 2.1 billion years ago, reports Sky News. This challenges the existing belief that animal life emerged approximately 635 million years ago. The discovery, located in the Franceville Basin near Gabon, reveals evidence of an ancient ecosystem linked to underwater volcanic activity following continental collisions. Although these early life forms did not proliferate globally due to localized water conditions and persistent hostile environments researchers speculate this marks a significant early phase in the evolution towards modern animal biodiversity.
