A new study suggests that the Last Universal Common Ancestor (LUCA) of all life on Earth existed around 4.2 billion years ago, much earlier than previously thought, and likely had an early immune system, indicating that life was fighting off viruses from its very beginnings.
A new study suggests that the Last Universal Common Ancestor (LUCA) of all life on Earth lived around 4.2 billion years ago, shortly after Earth's formation, and likely had an immune system fighting primordial viruses, indicating complex biological features early in life's history.
