A study led by Cardiff University proposes complex life could have started 1.5 billion years earlier than believed, indicating conditions for life more than 2 billion years ago. Research suggests a collision of two continental plates created a nutrient-rich environment fostering complex life evolution, challenging the consensus of animal life emergence 635 million years ago.
French chemist Louis Pasteur showed life only emerges from existing life forms, raising questions about the initial lifeform's origin. Current studies in Gabon suggest primordial conditions 2.1 billion years ago enabled the evolution of complex life, pivotal for the shift from unicellular to advanced forms.
