Indigo dye for clothing is a lot older than the invention of blue jeans — almost 6,000 years older, to be exact.

Scientists have found Andean cotton fabric from Peru with traces of the popular dye, according to new research in the journal Science Advances. The team behind the discovery say this blue scrap of fabric may rewrite the history of clothing.
