A GLI3 variant in Denisovans and Neanderthals may have increased polydactyly. Six-fingered figures appear in myths globally—from Native American to Australian Aboriginal traditions. Six-fingered handprints even show up in Chaco Canyon cave paintings, suggesting this trait wasn't always seen as a deformity. The Dilda family in Brazil shows these extra digits can be fully functional! 🧬🖐️
