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.
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. [Image Gallery: New Human Ancestors from Kenya]
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, California.
Ice Age era 'Lion Man' is World Earliest Figurative Sculpture:

From The Art Newspaper:
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 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
