Daily Mail : NASA scientists have reported finding the amino acid isovaline in samples of meteorites that came from asteroids. This discovery suggests that life on Earth began in space, because most of the isovaline from the meteorites was left-handed and life on Earth uses the left-handed kind of amino acid exclusively. This suggests that perhaps left-handed life got its start in space, where conditions in asteroids favored the creation of left-handed amino acids. Life in other star systems with different early conditions could have built up around right-handed amino acids, said NASA’s Daniel Glavin.
