The diamonds and the Origin of Life


Small pieces of diamond fake an embryonic Earth may contain the oldest traces of life, according to a study. The analysis showed that the crystals contain a type of carbon often associated with plants and bacteria. The rare gems were found inside zircon crystals, formed a few hundred million years after the Earth formed. In an article published in the journal Nature the researchers caution that the results are not definitive proof of early life forms, but "do not exclude" the possibility.
