Scientists might have just swabbed a 500-year-old drawing and found traces of Leonardo da Vinci’s DNA—no joke! They used a super gentle method to collect tiny bits of skin, sweat, and dust from his artwork and letters, and found Y-chromosome markers that match people from Tuscany, where Leo was born. It’s not 100% proof it’s his, but it’s the closest we’ve ever gotten to connecting the genius to his art on a genetic level. History nerds, this is wild! #Science #LeonardoDaVinci #DNA
