    Highlights
    * Genome sequencing of a Late Pleistocene human (MZR, ∼14.0 kya) in
    Southwest China
    * MZR represents an early diversified modern human lineage in East Asia
    * Genetic stratification in ancient southern populations of East/Southeast
    Asia
    * MZR deeply links to the East Asian ancestry that contributed to First Americans

    Summary
    Southern East Asia is the dispersal center regarding the prehistoric
    settlement and migrations of modern humans in Asia-Pacific regions.
    However, the settlement pattern and population structure of paleolithic
    humans in this region remain elusive, and ancient DNA can provide
    direct information. Here, we sequenced the genome of a Late
    Pleistocene hominin (MZR), dated ∼14.0 thousand years ago from
    Red Deer Cave located in Southwest China, which was previously
    reported possessing mosaic features of modern and archaic hominins.
    MZR is the first Late Pleistocene genome from southern East Asia. Our
    results indicate that MZR is a modern human who represents an early
    diversified lineage in East Asia. The mtDNA of MZR belongs to an
    extinct basal lineage of the M9 haplogroup, reflecting a rich matrilineal diversity in southern East Asia during the Late Pleistocene. Combined
    with the published data, we detected clear genetic stratification in
    ancient southern populations of East/Southeast Asia and some degree
    of south-versus-north divergency during the Late Pleistocene, and
    MZR was identified as a southern East Asian who exhibits genetic
    continuity to present day populations. Markedly, MZR is linked deeply
    to the East Asian ancestry that contributed to First Americans.
