    Researchers have long argued that regions
    deep in the Earth’s oceans may harbor sites
    from which all terrestrial life sprung. In
    the Atlantic, they gave the name “Lost City”
    to a jagged landscape of eerie spires under
    which they proposed that the life-preceding
    chemistry may have churned.

    And now for the first time, specialists have
    succeeded in getting a glimpse of this
    potential Garden of Eden.

    A report in the journal Science on Thursday
    tells of a 30-person team drilling deep into
    a region of the Mid-Atlantic seabed and
    pulling up nearly a mile of extremely rare
    rocky material. Never before has a sample so
    massive and from such a great depth come to
    light. The material is central to a major
    theory on the origin of life.

    “We did it,” said Frieder Klein, an expedition
    team member at the Woods Hole Oceanographic
    Institution on Cape Cod in Massachusetts. “We
    now have a treasure trove of rocks that will
    let us systematically study the processes that
    people believe are relevant to the emergence
    of life on the planet.”
