Scientists reconstructed LUCA's genome, the last common ancestor of all life on Earth.

Scientists reconstructed LUCA's genome, the last universal common ancestor of all life on Earth, using 700 curated genomes from bacteria and archaea. Estimated to have lived 4.2 billion years ago, LUCA's small genome suggests it was complex but lacked evidence of photosynthesis or nitrogen fixation. This research offers new perspectives on life's origin and evolution.
