American scientists from the Cleveland and Kent State University Museum of Natural History revealed a new hypothesis of the emergence of stone tools. According to assumptions, the first people first used such vehicles sharply by nature before they started to make their own on their own. The study was published scientifically magazine Archaeometry.
The team carried out field studies in different parts of the world, including Kenya and Oman, where the pointed stones called “Naturalites” were found in large amounts in nature.
The researchers suggested that only after using the stones from the nature of the old people sharply, a selective pressure emerged that forced their own stone tools to start to paste at any time.
For example, one of the potential motivations for exaltation is how to get sharp stone defects under the conditions of a limited bidding problem and naturalness of naturalness.
Or, perhaps exaltation was a way of reaching the stone with the desired features instead of spent time and energy to improve the natural invention of nature, to seek time and energy.
The new hypothesis offers a more economical explanation of the origin of stone technologies than previous theories. Now archaeologists have to control this idea, those looking for evidence of the use of naturalnesses 3 to 6 million years ago.
Previously, scientists learnedHow did they learn to survive in extreme conditions of the old ancestors of man.
