Evolution is learning from past mistakes in order to progress. In music, evolution is different. There are not new musical notes, compasses, métricas, etc., because it’s like numbers, there are not new symbols to represent new amounts. But, there are new rithyms which use combinations of older rithyms. Reggaeton is that but the vocabulary used and the songs thematic is the poorest. I would uninvent that music for the world welfare. And mine too.
