    There is an interesting article on the cladistics of fossil men. It places
    homo erectus morphologically much closer to modern man. I would love to
    hear this talk because it sounds like she is arguing for the union of H.
    erectus and H. sapiens--something several paleoanthropologists, like
    Jelinek, R. Leakey and others, have argued for.

    Abstract:
    "In the past few years, new discoveries (Atapuerca, Dmanisi, Buia) and new
    reappraisals of the chronological pattern of human evolution during the
    Pleistocene in Asia and Africa (e.g., Modjokerto, Ngandong and
    Longgupo--but also in Europe) have suggested an earlier emergence of Homo
    sapiens.

    "The new paradigm implies not only an earlier spread of H. sapiens into
    Europe but also a more recent date for the last occurrence of H. erectus in
    Asia. Is this new paradigm well founded, or should the definition of the
    species H. erectus and H. sapiens instead be reconsidered?"

    "A numerical cladistic analysis was carried out, initially on 468 cranial
    features (123 morphological characters and 345 metrical data) and 67 OTUs.
    This showed that, when using ontogenetic information for coding, Homo
    erectus is a plesion close to the origin of Homo sapiens. Moreover, when
    the species H. ergaster and the grade H. habilis are taken into account,
    most of the Pleistocene human fossils from Africa, as well as Solo and
    Zhoukoudian, appear to be affiliated to Homo sapiens."

    "The result of this analysis can be read as indicating a radiation of Homo
    in East Africa. This proposal forms part of a synthesis which takes into
    account independent chronological and paleoenvironmental data." Valery
