Was Lucy a Butcher?

New bones found suggest that tool use has started 800000 years earlier than we had thought.
Early human ancestors may have been using tools about 800,000 years earlier
than thought, according to a new study based on newfound bone
evidence—prehistoric leftovers linked to the famed "Lucy"
fossil's species.
The discovery suggests, to at least one scientist, that
tool use may extend as far back as five million years ago, to the last common
ancestor of chimps and humans.
