    NEW HUMAN ANCESTOR?
    By Kenneth Chang

    April 22 - Two and a half million years ago near a lake in Ethiopia, a
    humanlike creature raised a stone and smashed it down on an antelope bone to
    get at the marrow and fat inside.

    The hominid is long gone, but the broken antelope bone remains, the earliest
    known evidence of a stone tool used to butcher an animal. <snip>

    The mangled antelope bone shows the hominids of Ethiopia, probably
    scavengers, not hunters, had added high-nutrition marrow to their diets.
    Many anthropologists hypothesize that this change of diet spurred the
    development of stone technology and the evolution of larger, presumably more
    intelligent, brains.

    Discoveries like these have sent vegetarians into hiding and spurred the
    current interest in animal-based paleolithic diets.
