Question

tell me The indus valley civilization discovery in history project ​

Answer 1

Answer:

The civilization was first identified in 1921 at Harappa in the Punjab region and then in 1922 at Mohenjo-daro (Mohenjodaro), near the Indus River in the Sindh (Sind) region. Both sites are in present-day Pakistan, in Punjab and Sindh provinces, respectively.

Sir John Hubert Marshall led an excavation campaign in 1921-1922, during which he discovered the ruins of the city of Harappa. By 1931, the Mohenjo-daro site had been mostly excavated by Marshall and Sir Mortimer Wheeler. By 1999, over 1,056 cities and settlements of the Indus Civilization were located.

Proto-Dravidian (the ancestor of all known Dravidian languages) was probly spoken by the Early Harappans, say c. 3200-2600 BCE. Its roots -- which are beyond reconstruction -- of course go back to the origins of human language, as is the case with any other language: every language is equally old in this sense.
