Components of DNA found in meteorites

    Thought there'd be a thread on this already.
    The components of DNA have now been confirmed to exist in extraterrestrial meteorites. Meteorites hold a record of the chemicals that existed in the early Solar System and that may have been a crucial source of the organic compounds that gave rise to life on Earth. Since the 1960s, scientists have been trying to find proof that nucleobases, the building blocks of our genetic material, came to Earth on meteorites.

    New research, published next week in the Proceedings of the National Academy of Sciences, indicates that certain nucleobases do reach the Earth from extraterrestrial sources, by way of certain meteorites, and in greater diversity and quantity than previously thought.
    These results have far-reaching implications. The earliest forms of life on Earth may have been assembled from materials delivered to Earth by meteorites.

    "This shows us that meteorites may have been molecular tool kits, which provided the essential building blocks for life on Earth," Cleaves said.

    That's really cool I think, always liked that Panspermia theory:)
