Get this: a single strand of hair found in an ancient Inca khipu (those knotted-string record-keeping devices) just rewrote what we thought we knew about Inca society. Turns out, it wasn’t just elite dudes making these—commoners and even women were in on the action! Scientists traced the hair to a regular person’s diet and region, proving khipu literacy was way more inclusive than anyone guessed. How wild is that? #History #IncaEmpire #HistoryRewrite
