People with six fingers, or polydactyly, have an extra digit on one or both hands. This is a congenital anomaly, meaning it's present at birth. The extra finger is usually smaller and less developed than the other fingers.
Understanding Polydactyly
Polydactyly, also known as hyperdactyly, is a condition affecting both humans and animals. It results in supernumerary (extra) fingers and/or toes. The extra digits can vary in size and function, ranging from small, fleshy projections to fully formed fingers or toes with separate joints. As seen in the example of J.J. Weaver, a person can be born with six fingers on one hand. [Source: YouTube video of J.J. Weaver] Other documented cases include individuals with six fingers on each hand and six toes on each foot [Source: Reddit post about Edward]. The aye-aye, a lemur species from Madagascar, also possesses an extra digit, a “pseudothumb”, used for grasping [Source: The Conversation article]. Even fictional characters like Stan from Gravity Falls have been depicted with six fingers in certain scenes [Source: Reddit discussion about Gravity Falls]. The condition is frequently addressed medically, with doctors usually able to identify it at birth [Source: Boston Children's Hospital]. Sometimes, the condition is even woven into narratives, as shown in the book "Satan Has Six Fingers." [Source: Amazon listing].
Causes and Types
While the exact cause of polydactyly isn't always known, it's often linked to genetic factors. Some cases are hereditary, passed down through families. Other cases can be associated with genetic syndromes or mutations.
Treatment
Treatment options for polydactyly depend on the severity and location of the extra digits. Surgical removal is a common procedure to remove extra fingers or toes.
