Musical Influence for Jamaican Music

It is amazing what other types of music can influence main stream music. For example, Ska is a certain type of music that has strongly influenced Jamaican Reggae music. To first look at Ska it does not seem as though this type of musical genre could possibly have anything to do with the popular Reggae music, especially the dance steps involved in Ska. http://www.youtube.com/watch?v=CDAiQ-P7GoA I personally think that this is a far stretch from what Reggae is today. http://www.youtube.com/watch?v=0IZ_xLaSfXk I can honestly say that eventhough it seems more rhythmic, I would perfer to do the more modern version of Reggae than it's original type of dance.
