Late in the Hadean Eon, Earth's earliest period, some 4 billion years ago, first life chemicals are believed to have come together. Earth's surface seethed with vulcanic activity close to Earth's first lakes, and meteors crashed down regularly importing new chemicals from space. New experiments about the chemical evolution of prebiotic amino acid linkages mimic mild conditions during the late Hadean Eon. Artist's depiction.
