Washington, December 19 (ANI): A new study has found evidence which indicates that early humans were dividing their living spaces into kitchens and work areas much earlier than previously thought.
Archaeologists discovered evidence of this coordinated living at a hominid site at Gesher Benot Ya'aqov, Israel from about 800,000 years ago.
Scientists aren't sure exactly who lived there, but it predates the appearance of modern humans, so it was likely a human ancestor such as Homo erectus.
Yet, this advanced organizational skill was thought to be a marker of modern human intelligence.
Before now, the only concrete proof for divided living spaces dated back to only 100,000 years ago.
"Seeing this at such an early site was surprising. This means there was some ability or some need or requirement of organization," said archaeozoologist Rivka Rabinovich of the Hebrew University of Jerusalem.
Rabinovich and her colleagues, led by Nira Alperson-Afil, also of the University of Jerusalem, excavated the remains of an early human encampment on the shores of an ancient lake.
They found used pieces of flint, rock tools, crab shells, fish bones, and bits of fruits, seeds, nuts, bark and wood.
The excavation proved that the hominids living there were hunting not just land mammals, but sea creatures like fish, crabs and turtles, and these remains were not scattered randomly, but instead concentrated in certain areas.
The food remains and stone-tool bits were found in one area, while the flint scraps (likely from cooking tools) were clustered in another region.
According to the scientists, the camp's hearth was located in the southeast area of the site, and that food-making and eating took place mostly near there.
In addition, most of the stone-tool remains - bits of basalt and limestone rocks that had been shaped into usable instruments - were also clustered near the hearth.
In contrast, the northwestern region held most of the flint remains and evidence of fish preparation.
The archaeologists think this could have been a working area for the early human inhabitants.
"The designation of different areas for different activities indicates a formalized conceptualization of living space, often considered to reflect sophisticated cognition and thought to be unique to Homo sapiens," according to the researchers.
This skill also indicates the inhabitants had some kind of social organization and coordination between individuals.
"It clearly shows that they're much more advanced than we previously thought," said co-author Irit Zohar of the University of Haifa. (ANI)
