Why is it said that the people of the Indus Valley civilization were technologically advanced?

         

         We may think of dentistry to be a modern practice, but it is not so. The people of the Indus Valley civilization already had knowledge of dentistry! Archaeological evidence from Indus Valley sites shows the first evidence of drilling human teeth, in a living person.

          What is more important about these people is that, they were the first to measure length, mass, and time accurately.

 

          People were familiar with new techniques in metallurgy and produced brass, copper, bronze and ivory which were used to make ornaments, utensils, seals etc. The people of the Indus Valley civilization developed techniques and tools to measure length, weight and time with impressive accuracy. They used the same for commercial as well as building purpose.

          Engineering skills were at its heights, and this is clear from the construction of docks at Lothal. They evolved some new techniques in metallurgy and produced copper, bronze, led and tin.
