| A stone tool found at Ain Boucherit in Algeria which could challenge East Africa's claim to be the cradle of humanity |
Archaeologists in Algeria have discovered stone tools and cut animal bones that may be up to 2.4 million years old, bringing into question East Africa's title as the cradle of humanity, according to research published Thursday in the journal Science.
The artefacts - more ancient than those discovered in the region until now - were found in Setif, some 200 miles (300 kilometres) east of Algiers, by a team of international researchers, including Algerians.
The tools closely resemble those called Oldowan, found until now mainly in East Africa.
The tools were unearthed near dozens of fossilised animal bones which contained cut marks, as if relics of prehistoric butchers.
The bones came from animals including the ancestors of crocodiles, elephants and hippopotamuses.
"East Africa is widely considered to be the birthplace of stone tool use by our ancient hominid ancestors - the earliest examples of which date as far back as about 2.6 million years ago," said the report in Science.

"The new findings make Ain Boucherit the oldest site in northern Africa with in situ evidence of hominin meat use with associated stone tools and they suggest that other similarly early sites could be found outside of the Eastern Africa Rift."
One hypothesis is that early ancestors of modern day humans quickly carried stone tools with them out of East Africa and into other regions of the continent.
Another is a "multiple origin scenario," in which early hominids made and used tools in both East and North Africa.

A team of archaeologists from Germany and Egypt found a colossal 26-foot (7.9 meter) statue in a Cairo slum in the Souq Al-Khamis district, near the ruins of the ancient city of Heliopolis in Egypt on March 9, 2017. Experts believe that the 3,000-year old statue to be of pharaoh Ramses II, one of the country's most famous ancient rulers. It is being hailed as one of the most important discoveries ever by the Egyptian Antiquities Ministry.
Here's a look at other famous archaeological findings around the globe.

The Rosetta Stone
Carved in 196 B.C., the Rosetta Stone was found by French soldiers who were rebuilding a fort in Egypt in 1799. The rock stele is inscribed with a decree issued attesting to the generosity of King Ptolemy V. The decree appears in three scripts: the upper text is ancient Egyptian hieroglyphs, the middle portion is Demotic script, and the lowest is ancient Greek. Since it shows essentially the same text in all three scripts, the stone provided a key to the modern understanding of Egyptian symbols.

King Tutankhamun's tomb
The tomb of the Egyptian pharaoh was discovered in 1922 by British archaeologist Howard Carter (L) and Lord Carnarvon in the Valley of the Kings, Egypt. The discovery received worldwide press coverage, sparking a renewed public interest in ancient Egypt. Tutankhamen's mask, now in the Egyptian Museum, remains a popular symbol of the prehistoric Egypt.

"The site of Ain Lahnech is the second oldest in the world after Gona in Ethiopia, which goes back to 2.6 million years ago and is widely considered the cradle of humanity," lead author Mohamed Sahouni told AFP.
The discoveries were made in two layers - one dating to 2.4 million years ago and the second dating to 1.9 million years old.
The findings suggest that the ancestors of modern people were present in north Africa at least 600,000 years earlier than scientists thought.

Until now, the oldest known tools from northern Africa were 1.8 million years old, and were found at a nearby site.
No humans remains were found. Therefore, scientists don't know what species of hominids were at the site, or what ancient cousin of homo sapiens (who appeared much later), used these tools.
The dig was undertaken by experts from research institutions in Spain, Algeria, Australia and France.
"Now that Ain Boucherit has yielded Oldowan archeology estimated to 2.4 million years ago, Northern Africa and the Sahara may be a repository of further archaeological materials," the study said.
"Based on the potential of Ain Boucherit and the adjacent sedimentary basins, we suggest that hominin fossils and Oldowan artifacts as old as those documented in East Africa could be discovered in North Africa as well."
