Archaeologists in Lüscherz, near Lake Bienne (Bielersee) in Switzerland 🇨🇭, uncovered a 4700 year-old ball of yarn dating back to around 2700 BC an extraordinary discovery from the #Neolithic era.

Its preservation is exceptional, as organic materials like yarn rarely survive for thousands of years. Scientists believe the yarn was protected in an oxygen-free environment such as lake sediment or peat, which prevented decay #globalmuseum #archaeology
