Crisscross engravings suggest a smarter Homo Erectus. The scratches found on a fossilized shell from Indonesia may be the earliest imprinting done by a human ancestor, a study has revealed. The etching is no less than 430,000 years old, implying that it was carried out by the long wiped-out Homo Erectus, said the study.
Numerous fossilized freshwater mussel shells were uncovered and gathered in Java by Dutch researcher Eugene Dubois in the 1890s, then put away in boxes for quite a long time in the Dutch city of Leiden. In May 2007, Mr Munro took photographs of them as a step in his PHD studies. The engravings emerged plainly on the digital photographs though they had not been obvious to the bare eye.
Homo Erectus, the oldest hominid had wandered around the Indonesian island of Java, where the shell was found, no less than 1 million years prior. Until now the oldest traces of humans crafting found are around 130,000 years old.
Early African Homo Erectus fossils are the most ancient early humans remains discovered until the present day. Their bodies were human-like with moderately lengthened legs and shorter arms in contrast with the torso’s size.
On the off chance that this new hypothesis is valid, researchers say the discoveries may constrain scientist to reconsider how human society evolved.
The shell has a clean edge and a zigzag engraving that were produced using cutting or scratching, which implies our predecessors were more astute than beforehand thought, according to Dr. Stephen Munro a paleoanthropologist at the Australian National College. He added that this was the first time scientists discovered traces of Homo Erectus acting in such a way.
The geometric imprinting in the shell can be considered an additional evidence of early men’s knowledge, since the shapes are an indication of present day cognitive capacities. Nevertheless, the starting point of such conduct is still debatable. This finding challenges the hypothesis that a certain type of behavioral development is limited to Homo Sapiens and that its origins are just African, analysts commented.
Also, researchers believe it is safe to assume that the object could have been utilized as a hunting weapon or a tool for scavenging ants.
The study likewise indicates that these early hominids had a cunning way of opening freshwater mussels. Apparently they relied on a sharp shark tooth to force a hole at the point where the muscle that holds the shell shut is joined. This required precision and might also point out to some knowledge about the structure of the molluscs.
