Rats shake their bodies to music. The rhythm that people get into is about two beats/sec, and from an "elephant time, rat time" perspective, we tend to think that rats would prefer a faster rhythm. They don't. Instead, they shake their heads in the same rhythm as humans. Maybe the evolutionary origins of music are older than we thought.

ネズミも音楽でノってくる。人が一番ノるリズムは毎秒２拍ぐらいで、「ゾウの時間ネズミの時間」的に考えればネズミはもっと早いリズムを好みそうだが、実際はそうではなく、人間と同じリズムを好んで頭を振るそうな。音楽の進化的起源は意外ともっと古いのかも
