    Partitioning the genomic journey to becoming Homo sapiens

    Abstract
    What makes us human? Homo sapiens diverged
    from its ancestors in fundamental ways,
    reflected in recent genomic acquisitions
    like the PAR2-Y chromosome translocation.
    Here we show that despite morphological and
    cultural differences between modern and
    archaic humans, these human groups share
    these recent acquisitions. Our modern
    lineage shows recent functional variants
    in only 56 genes, of which 24 are linked to
    brain functions and skull morphology.
    Nevertheless, these acquisitions failed to
    introgress into Neanderthals when archaic
    and modern populations admixed after 350 kya,
    suggesting their exclusive link to the modern
    human niche or that NeanderthalrCOs small
    population size hindered their spread. Taken
    together, our results point to a scenario
    where Modern and Archaic should be regarded
    as populations of an otherwise common human
    species, which independently accumulated
    mutations and cultural innovations.

    I have been arguing along virtually identical lines,
    that the term "Species" is utterly useless here and
    we should refer to them as "Populations," for years
    on end.
