It has been revealed in a study of baby monkeys that they are born with an appreciation of music! In this video  http://bit.ly/Pe2Eq you can clearly see that the monkey pulls the string to play the music. When the music stops the monkey clearly pulls the string to make it start again.

Scientists originally thought that humans were the only creature that was born to appreciate music (even though we evolved!) So now we know that the chip preferred to listen to music than being in silence, i think the next research should look into what type of music!!
