Oldest Stone Hand Axes Found:

Scientists have unearthed and dated some of the oldest stone
hand axes on Earth. The ancient tools, unearthed in Ethiopia in the last
two decades, date to 1.75 million years ago.
The tools roughly coincided with the emergence of an ancient human ancestor called
Homo erectus, and
fossilized H. erectus remains were also found at the same site, said
study author Yonas Beyene, an archaeologist at the Association for
Research and Conservation of Culture in Ethiopia.
Collectively, the
finding suggests an ancient tool-making technique may have arisen with
the evolution of the new species.
This discovery shows that the technology began with the appearance of
Homo erectus," Beyene told LiveScience. "We think it might be related
to the change of species."
The findings were described Jan. 28 in the journal Proceedings of the National Academy of Sciences,
Human ancestors used
primitive tools
as far back as 2.6 million years ago, when Homo habilis roamed the
Earth. But those tools, called Oldowan tools, weren't much more than
rock flakes knapped in a slapdash manner to have a sharp edge.
But nearly a million years later, more sophisticated two-sided hand
axes or cleavers emerged. These Aucheulean tools could be up to 7.8
inches (20 centimeters) long and were probably used to
butcher meat.
Scientists recently discovered tools of this type a few hundred miles
away near Lake Turkana in Kenya, dating to 1.76 million years ago. [

Because of its coincidence with the appearance of Homo erectus,
scientists believed the sophisticated tools were made by the newer
species of Homo, but proving that was tricky, because the dating of
fossils and tools wasn't precise enough, said study co-author Paul
Renne, a geochronologist and director of the Berkeley Geochronology
Center in Berkeley, Cal
ifornia.
Ice Age era 'Lion Man' is World Earliest Figurative Sculpture:

The star exhibit initially promised for the British
Museum’s “Ice Age Art” show will not be coming—but for a good reason.
New pieces of Ulm’s Lion Man sculpture have been discovered and
it has been found to be much older than originally thought, at around
40,000 years. This makes it the world’s earliest figurative sculpture.
At the London exhibition, which opens on 7 February, a replica from the
Ulm Museum will instead go on display.
The story of the discovery of the
Lion Man goes
back to August 1939, when fragments of mammoth ivory were excavated at
the back of the Stadel Cave in the Swabian Alps, south-west Germany.
This was a few days before the outbreak of the Second World War. When it
was eventually reassembled in 1970, it was regarded as a standing bear
or big cat, but with human characteristics.
The ivory from which
the figure had been carved had broken into myriad fragments. When first
reconstructed, around 200 pieces were incorporated into the 30cm-tall
sculpture, with about 30% of its volume missing.
Further
fragments were later found among the previously excavated material and
these were added to the figure in 1989. At this point, the sculpture was
recognised as representing a lion. Most specialists have regarded it as
male, although paleontologist Elisabeth Schmid controversially argued
that it was female, suggesting that early society might have been
matriarchal.
The latest news is that almost 1,000 further
fragments of the statue have been found, following recent excavations in
the Stadel Cave by Claus-Joachim Kind. Most of these are minute, but a
few are several centimetres long. Some of the larger pieces are now
being reintegrated into the figure.
Conservators have removed
the 20th-century glue and filler from the 1989 reconstruction, and are
now painstakingly reassembling the
Lion Man, using computer-imaging techniques. “It is an enormous 3D puzzle”, says the British Museum curator Jill Cook.
The
new reconstruction will give a much better idea of the original. In
particular, the back of the neck will be more accurate, the right arm
will be more complete and the figure will be a few centimetres taller
