A group such as Nagoya University has newly discovered that modern humans living in the inland arid region of southern Jordan used the shells of the Red Sea 55 km away as a symbol.
It is known that modern humans, the ancestors of modern humans, existed at the same time as extinct ancient humans (such as Neanderthals) until about 4 years ago.What was the reason why only modern humans increased and reached us today, and ancient humans became extinct?
The researchers conducted a field survey in the Levant region (the eastern Mediterranean region), where the remains of both modern humans and Neanderthals remain, and attempted to clarify the differences in behavior between modern humans and Neanderthals. ..The study area is an inland arid region in the southern part of Jordan, far from the coast, but found shells from the Wadi Agar ruins and found that they were the inhabitants of modern humans at that time.
The two shells found were Tsumgatasode and Mukashitamoto, both of which are from the Red Sea.It is said that it is hard to think that it is edible because it is small in number and small, and it is brought from the Red Sea 2 km away.No record of any meaningful symbol being carried over 55 km has been found in the Neanderthal ruins of the region.
It is unclear whether the modern humans who lived in the Wadi Agar ruins moved to and from the Red Sea and brought in shells, or received them from another group living near the Red Sea, but the modern humans are in the suburbs. It turned out that unlike the Neanderthals who lived alone, they had the means to obtain coastal resources far from their place of residence.Connections with coastal areas are an effective countermeasure in inland dry areas where risks such as food shortages often occur.
This result is a valuable example showing the difference in behaviors taken by extinct humans and modern humans under almost the same conditions, and is expected to contribute to the elucidation of the behavioral characteristics of modern humans.
