Someone with polydactyly has 11 fingers.
Polydactyly is a condition where a person is born with extra fingers or toes. It's a congenital anomaly, meaning it's present from birth. While it can affect the hands and feet, resulting in more than the typical five digits on each, the question specifically focuses on the hands. Therefore, an individual with polydactyly affecting their hands could indeed possess 11 fingers. The reference mentions polydactyly as a congenital anomaly in humans resulting in supernumerary (extra) fingers or toes.
Another less common possibility mentioned in the reference is a pelvic digit. However, this is a bone formation near the pelvis, not a finger, and wouldn’t result in 11 fingers on the hands.
- Key takeaway: Polydactyly is the primary reason someone might have 11 fingers.
