Study: Rhesus Monkeys Make Bad Drummers

This will be of note to anyone looking to hire a drummer.  Scientists have determined that rhesus monkeys (Macaca mulatta) are not very good with a beat.  From PLOS ONE, a peer-reviewed journal:

It was recently shown that rhythmic entrainment, long considered a human-specific mechanism, can be demonstrated in a selected group of bird species, and, somewhat surprisingly, not in more closely related species such as nonhuman primates. This observation supports the vocal learning hypothesis that suggests rhythmic entrainment to be a by-product of the vocal learning mechanisms that are shared by several bird and mammal species, including humans, but that are only weakly developed, or missing entirely, in nonhuman primates. 

In other words, the little guys recognize rhythmic groups in music but they can’t seem to get the hang of the beat.  Read more here, if you must.
