    Strontium isotope ratios are widely used in
    archaeology to differentiate between local and non-local populations. Herein,
    strontium isotope ratios of 36 human tooth enamels from seven archaeological
    sites spanning the Early to Late Neolithic of northern Greece (7th–5th
    millennia B.C.E.) were analysed with the aim of providing new information
    relating to the movement of humans across the region. Local bioavailable 87Sr/86Sr signals were
    established using tooth enamel from 26 domestic animals from the same Neolithic
    sites. 87Sr/86Sr values of faunal
    enamel correlate well with predicted strontium isotope ratios of the local
    geology. This is consistent with animal management occurring at a local level,
    although at Late Neolithic sites strontium isotope values became more varied,
    potentially indicating changing herding practices. The strontium isotope
    analysis of human tooth enamel likewise suggests limited population movement
    within the Neolithic of northern Greece. Almost all individuals sampled
    exhibited 87Sr/86Sr values consistent
    with having spent their early life (during the period of tooth mineralisation)
    in the local area, although movement could have occurred between isotopically
    homogeneous areas. The strontium isotope ratios of only three individuals lay
    outside of the local bioavailable 87Sr/86Sr range and these individuals are interpreted as
    having spent their early lives in a region with a more radiogenic biologically
    available 87Sr/86Sr. Mobility patterns
    determined using Sr isotope analysis supports the current evidence for movement
    and exchange observed through studies of pottery circulation. Suggesting
    limited movement in the Early and Middle Neolithic and greater movement in the Late
