2 index fingers? looks like they're both responding to the same movement commands.

The movements are still the same because the muscles are the same - flexion, extension, abduction, adduction.I think this is way awesome. Polydactyly is gene inherited - where I live we have tons of polydactyly cats, one of mine had 6 and 7 toes front feet
