Experts suggest that the ancient people used them as weapons.
Previously in China archaeologists have discovered more than two hundred stone balls, but for a long time experts could not understand what they meant.
American scientists from the University of Wyoming launched their version.
They believe that the stone balls were used as projectiles. The ancient people could use stone balls to hunt and to protect their settlements.
Experts Violinschule University noted that in China at the moment, found a large number of round stone stones. They assume that ancient people used them as weapons. They just threw a stone at the victim, which could either hurt her, or to kill.
Many facts confirm the version put forward by the experts. So, in those places where they found the stones, archaeologists found animal bones, which could indicate that they were killed with stone missiles.
Scientists even conducted an experiment. They tried to throw a stone in the head, after which it was noted that such a projectile can deprive a person of consciousness. And if you exert more effort when throwing, and kill the victim.
Because of its primitiveness of the stones could enjoy great popularity among the ancient people. This is indicated by numerous finds of ancient artifacts.
It is worth Recalling that in Costa Rica were previously discovered large stone spheres. Scientists still can not understand their purpose. Many experts agree on the fact that the spheres symbolize the heavenly bodies.
