    Whether for cooking, heating, as a light
    source or for making toolsrCoit is assumed
    that fire was essential for the survival
    of people in the Ice Age. However, it is
    puzzling that hardly any well-preserved
    evidence of fireplaces from the coldest
    period of the Ice Age in Europe has been
    found so far.

    A group of scientists led by the
    University of Algarve and the University
    of Vienna has now been able to shed some
    light on the mystery of Ice Age fire.
    Their analysis of three hearths at a
    prehistoric site in Ukraine shows that
    people of the last Ice Age built
    different types of hearths and used
    mainly wood, but possibly also bones and
    fat, to fuel their fires. The results
    have been published in the journal
    Geoarchaeology.
    ...
    "We know that fire was widespread before
    and after this period, but there is
    little evidence from the height of the
    Ice Age," says William Murphree, lead
    author of the study and geoarchaeologist
    at the University of Algarve.

    One interesting finding from this was
    that these fires reached temperatures of
    more than 600-#C, which proves
    sophisticated mastery of pyrotechnics
    even in the face of extreme environmental
    stresses.

    The analysis also shows that humans used
    wood as their main fuel during the peak
    of the Ice Age, with charcoal analyses
    indicating spruce wood. However, other
    fuels such as bone or fat could have
    been used.
    ...
    "People perfectly controlled the fire
    and knew how to use it in different ways,
    depending on the purpose of the fire. But
    our results also show that these
    hunter-gatherers used the same place at
    different times of the year during their
    annual migrations," explains Nigst.

    Despite these new findings, the small
    number of fireplaces from the Last
    Glacial Maximum remains puzzling. "Was
    most of the evidence destroyed by the
    ice-age-typical, alternating freezing
    and thawing of the soil?" asks Murphree.

    "Or did people not find enough fuel
    during the Last Glacial Maximum? Did
    they not use fire, but instead rely on
    other technological solutions?" adds
    Nigst.
