Just found this thread and while reading the discussion followed the link to DinoRaul's page.  Despite having searched for some early human models (and finding nothing) I was thrilled to see his Homo Habilis.  I'll be sending him an oh-so-nice email begging for a few others from our family tree like Sahelanthropus tchadensis or the ever popular  Austrolopithecus afarensis. 

  Is anyone here an anthropologist by chance?
