In many news sites (1) , (2), it is written that Indus civilization is over 8000 years old by a study by IIT KGP and Archaeological association of India. However the wiki dates don't align with these dates as far as I understand. Could someone give me clarification here on the actual dates? I mean, have historians in general accepted these dates or not?
One commentor has noted that the source of the claim by the newsite is from a Nature article which talks about Harrapan civilization and not Indus civilization. But many site consider them as same. *
The Indus civilization is also known as the Harappan civilization, after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab province of British India and is now Punjab, Pakistan. The discovery of Harappa and soon afterwards Mohenjo-daro was the culmination of work that had begun after the founding of the Archaeological Survey of India in the British Raj in 1861. There were earlier and later cultures called Early Harappan and Late Harappan in the same area.
I know that it maybe perfectly valid that Wiki just didn't update but I seek an answer involving cross examination. That is, what the other external sources are saying about the IIT KGP studies.
