cosmicsolutions Discover The Mystery Of Ancient Civilizations

"The Indus Valley Civilization has yielded evidence of dentistry being practiced as far back as 7000 BC. This earliest form of dentistry involved curing tooth related disorders with bow drills operated, perhaps, by skilled bead craftsmen.

The reconstruction of this ancient form of dentistry showed that the methods used were reliable and effective. Cavities of 3.5 mm depth with concentric grooves indicate use of a drill tool. The age of the teeth has been estimated at 9000 years."

"The wheel originated in ancient Sumer (modern Iraq) in the 5th millennium BC, originally in the function of potter's wheels. The wheel reached Europe and India (the Indus Valley civilization) in the 4th millennium BC. Near the northern side of the Caucasus several graves were found, in which since 3700 BC people had been buried on wagons or carts. The earliest depiction of what may be a wheeled vehicle is on the Bronocice pot, a circa 3500 BC clay pot excavated in southern Poland.

What is particularly interesting about the wheel is that wheels only occur in nature in the microscopic form, so man's use of the wheel could not have been in mimicry of nature."
