Complex Life Started Nearly a Billion Years Earlier Than We Thought

New research indicates that complex life began forming almost a billion years earlier than previously thought. Using an expanded molecular clock approach, scientists mapped out a clearer timeline of how early gene families evolved. They discovered that key eukaryotic features emerged long before mitochondria or atmospheric oxygen became abundant. The result is a new evolutionary [...]
