- Q 1/20Score 0What did the Miller-Urey experiments tell us about life on Earth?29All living things are related, as we are all descendants of a common ancestor cell that formed approximately 3.95 billion years agoLife probably originated from outer space and arrived on the Earth in a comet or meteoriteAll proteins are made up of long chains of amino acids, folded to form a specific shapeSome complex biological molecules can form in the absence of living things (given the conditions found on the Earth 4 billion years ago)
