Found stone tools by age 3, 3 million years





The remains Kenyanthropus, found earlier excavations in Lomekvi 3 i>

On the 80 th annual meeting of paleontologists in Los Angeles decided to update the history of the emergence of people. Group of paleontologists presented scientific paper describing the oldest stone tools by age 3, 3 million years. This is 700 more than 000 years old tools than were known to science before.

Naturally, a man of understanding has not yet appeared in such ancient times. Tools belonged to more ancient hominids. Most likely, this кениантропы, whose remains were found nearby and dated 3, 2-3, 5 million years. Thus, our ancestors were able to make tools long before humans 2, 6 million years ago.

After finding Kenyanthropus anthropologists disagreed, they were able to use hand tools. Now it's the missing link found. It is possible that Kenyanthropus was the common ancestor for later hominids.




In any case, support the theory that complex hand tools were created long before the appearance of Homo habilis 2, 6 million years ago and Neanderthals. No one knows how many species were able to do it (Australopithecus? Kenyanthropus?) And one of them later became the ancestor of humans and modern apes, and who died out as a result of evolutionary selection.

At the field in Lomekvi 3 found rich placer stone tools by age 3, 3 million years: a total of about 150 artifacts, including 20 pieces that accurately dated 3, 3 million years ago, and the rest were found on the surface, but also belong to the same collection, apparently. Among them are well-preserved yadrischa, chips and anvil, which is processed stones hit them. Found another stone weighing 15 kg, with traces of processing. Scientists still do not understand what this tool and how it can be used.




The most valuable of the finds - нуклеус and how ideally suited to it. Other tools demonstrate that Kenyanthropus pretty well owned by cleaving stone and worked mainly with his right hand. But Nucleus and how exactly prove that it is the result of processing by human hand. More precisely, the hominid hand, very similar to modern man's hand: they already knew how to , such as pinching, take things with your fingers, etc.
