    The ecology, subsistence and diet of
    ~45,000-year-old Homo sapiens at Ilsenhöhle
    in Ranis, Germany


    Abstract
    Recent excavations at Ranis (Germany) identified
    an early dispersal of Homo sapiens into the higher
    latitudes of Europe by 45,000 years ago. Here we
    integrate results from zooarchaeology,
    palaeoproteomics, sediment DNA and stable isotopes
    to characterize the ecology, subsistence and diet
    of these early H. sapiens. We assessed all bone
    remains (n = 1,754) from the 2016–2022 excavations
    through morphology (n = 1,218) or palaeoproteomics
    (zooarchaeology by mass spectrometry (n = 536) and
    species by proteome investigation (n = 212)).
    Dominant taxa include reindeer, cave bear, woolly
    rhinoceros and horse, indicating cold climatic
    conditions. Numerous carnivore modifications,
    alongside sparse cut-marked and burnt bones,
    illustrate a predominant use of the site by
    hibernating cave bears and denning hyaenas,
    coupled with a fluctuating human presence. Faunal
    diversity and high carnivore input were further
    supported by ancient mammalian DNA recovered from
    26 sediment samples. Bulk collagen carbon and
    nitrogen stable isotope data from 52 animal and
    10 human remains confirm a cold steppe/tundra
    setting and indicate a homogenous human diet
    based on large terrestrial mammals. This
    lower-density archaeological signature matches
    other Lincombian–Ranisian–Jerzmanowician sites
    and is best explained by expedient visits of
    short duration by small, mobile groups of
    pioneer H. sapiens.


    "...confirm a cold steppe/tundra setting and
    indicate a homogenous human diet based on
    large terrestrial mammals."

    "In general, Upper Palaeolithic H. sapiens
    subsistence has been correlated with a shift
    in site use and occupation intensity and an
    expansion in diet breadth, to include larger
    proportions of smaller and faster animals,
    such as fish, birds, rabbits and foxes."
