Scientists now believe life began long before LUCA. Older organisms, now vanished, passed on vital genetic tools. These \'pre-LUCA\' ancestors developed complex biological functions. LUCA inherited these innovations, becoming the foundation for all life. This discovery reshapes our understanding of life\'s origins on Earth.
