This video is absolutely amazing. While it is enjoyable and comical to watch this sea lion 'dance' to the music, it also is a great finding for modern science and animal behaviorists. Until this study, animal behaviorists have maintained that the only animals that are able to keep a beat are humans and animals capable of voice mimicry. This would include parrots and some other birds. This study shows that other animals are capable of recognizing a beat in music.
What this says to me is that we have been asking questions of animals that they do not understand. Once this sea lion, named Ronan, was taught to bob its head to one song, it quickly caught on and was able to bob its head to multiple songs with multiple different beats. Sea lions do not grow up learning how to 'dance' from other sea lions, so how can humans expect them to 'dance' without being taught?
I think that if the people doing these studies can figure out new ways to let the animals know what we are asking of them, that we will quickly find that animals are much smarter than scientists once thought.
