a narrow pelvic breadth is specific to H.sapiens vs H.erectus/neand.

      Current Anthropology:
      Human Biology and the Origins of Homo
      <http://www.jstor.org/stable/10.1086/666726>open access

      New fossil discoveries relevant to the origin of Homo have overturned
      conventional wisdom about the nature of the australopiths & early Homo &
      particularly H.erectus incl.H.ergaster.
      They have eroded prior assumptions about the differences between these
      genera & complicated interpretations for the origin and evolution of Homo.
      This special issue surveys what is now known about the fossil evidence &
      the environmental context of early Homo.
      It also moves beyond the hard evidence, and sets the stage for integrated
      multi-disciplinary studies, to provide a framework for interpretation of
      the hard evidence.
      To understand the adaptive shifts at the origin of Homo, it is essential
      to have a solid understanding of how & why modern humans & other animals

      Contributors to this issue include pPAs, human biologists, behavorialists
      & modelers.
      We tasked each with bringing her or his special expertise to bear on the
      question of the origins & early evolution of Homo.
      The papers in this collection are a product of a week-long Wenner-Gren
      symposium held in March 2011,
      this introduction integrates this work & its significance for Homo.


      Body Size, Body Shape, and the Circumscription of the Genus Homo
      Trenton W Holliday thollid@...

      Since the 1984 discovery of the Nariokotome H.erectus/ergaster skeleton,
      it has been almost axiomatic that the emergence of Homo (sensu stricto)
      was characterized by an increase in body size to the modern human
      condition & an autapomorphic shift in body proportions to those found
      This was linked to a behavioral shift toward more intensive carnivory and
      wider ranging in the genus Homo.

      Recent fossil discoveries & re-analysis of the Nariokotome skeleton
      suggest a more complex evolutionary pattern.
      While early Homo tend to be larger than Australopithecus/Paranthropus,
      they were shorter on average than people today.

      Re-analysis of the Nariokotome pelvis along with the discovery of
      additional early & middle Pleistocene pelves indicate
      - a narrow bi-iliac (pelvic) breadth is an autapomorphy specific to
      - at least some early Homo (even H.ergaster/erectus) were characterized by
      higher humero-femoral indices than the H.sapiens average.

      All these data suggest a pattern of mosaic postcranial evolution in Homo,
      with implications for the increased ranging/carnivory model of the origin
      of Homo as well as for which species are included within the Homo hypodigm.
