New archaeological research from the Bhirrana site suggests the Indus Valley Civilisation may date back nearly 8,000 years.
Radiocarbon dating of pottery and animal remains indicates that early human settlement and agrarian communities developed much earlier than previously believed.
The Indus Valley Civilisation (also called the Harappan Civilisation) is traditionally dated between 2600 BCE and 1900 BCE.
Major urban centres include Harappa, Mohenjo-daro, Dholavira, and Rakhigarhi.
