Scientists still studying his dancing and now found that he has 14 different moves and 2 composite ones, that he doesn't 'repeat' the same 'choreography' when he hears the same song and that he made up some of his moves (but I don't know if I would not call them innate). All this does not only show that he likes and understand the concept of music and rhythm but also a high intelligence AND complex social behavior.
