Group dancing as the evolutionary origin of rhythmic entrainment in humans

An ecologically-valid approach to the evolutionary origins of rhythmic entrainment in humans has to address not one but two key issues: first, the capacity to generate acoustic rhythms, and second, the ability to entrain body movements to them. Most research in this area has ignored the first issue altogether and has instead placed all of the emphasis on motor entrainment skills per se. But this begs the question of how auditory rhythms came to …
