    Dominic Papineu, Ph.D., Department of Geosciences, University College London, and Matt Dodd, Ph.D., published the findings on the University of London's official website, where they found tiny silky, tiny tectonics, mineral particles and strips in striped iron-shaped rocks from northern Quebec, Canada.
    paper will be published in the journal Nature.
    two researchers have discovered micro-fossils and mineralized rocks that are at least 3.77 billion years old and could have been born as early as 4.28 billion years ago.
    if found to be true, it would set a new record for the oldest life on Earth.
    last year, scientists discovered a 3.7 billion-year-old fossil microbial blanket called stromatolites, believed to be the oldest fossil on Earth.
    , the first author of the paper, explains: Our findings support the theory that life was born from hot seabed hot springs shortly after the Earth was formed.
    when life on Earth began to develop, liquid water was present on both the Earth and the surface of Mars, which raised exciting questions in the search for traces of life off Earth.
    Dominic Papineu told Reuters in an interview: "The Earth formed about 4.5 billion years ago, the oceans appeared about 4.4 billion years ago, and if microbial fossils can prove that they were born 4.28 billion years ago, it does suggest that life may have occurred immediately after the formation of the ocean."
    " study found tiny thin wire and hetero-iron tubes with twisted structures, some connected to end protrusions and branches.
    some twisted long wires are coated with nano-scale hematite, which forms a slender twirical structure around the long wire.
    these microsumes formed during early rock formation.
    study also found microscopic rose knots and particles from minerals containing carbonates, phosphorite and graphite carbon.
    geochemistry, mineralogy, rock science and sedimentology support biological origin.
    researchers believe the fossil structure could prove that the silk found had traces of life.
    Because in scientific discoveries to date, only biological structures can explain the compositions they observe, phosphorite, carbonate and graphite carbon produced from biomass minerals that are destructed and oxidized, similar to fossil animals made up of these same minerals (e.g., animal biomedical carbonate-phosphorus ash in teeth and bones).
    study showed that some microbes around deep-sea hot springs did not significantly change their shape between the first 4 billion years of life, although it is not yet known what kind of gas they eat and breathe.
    also suggests a direction for the traces of life found in the geological record of Mars.
    2008, Dr. Dominic Papineau has been collecting striped iron rocks in northern Quebec, Canada, looking for traces of ancient life.
    The New York Times reported that many experts remain skeptical, and University of New South Wales geologist Martin J. Van Kranendonk believes the discovery may be a fossil-like substance, but there is no clear evidence that there were signs of life.
