Abstract
Rock art in the Four Corners area often includes pictures of hands and feet, which may be representational or symbolic. There is correlation between actual metatarsal bones and carvings of polydactyl feet. No duplicated hand bones have been found, but we postulate petroglyphs of polydactyl hands are a reflection of a real congenital difference.
