The family Da Silva in Brazil has a genetic oddity: all members have 6 fingers on each hand. A feature called polydactyly, and the family considers as an asset rather than as an anomaly. If Brazil win this year's World Cup, You can show all the titles on a single hand.

   The fingers are independent of each other? Each finger has a nervous 'circuit' and dedicated tendons? I saw that the boy plays guitar with five fingers, not 6. The sixth does not use it because 'offended' or for a question of style (or habit)?I would understand if it is an ancient genetic branch or is a recent genetic alteration.
