“Yoda” primates sing duets like opera stars

Tiny, ape-like creatures called tarsiere sing operatic-style duets together — but those who fail to hit the high notes may also fail to attract mates, scientists have recently suggested.

With their large, pointed ears and expressive eyes, nocturnal tarsiers bear a striking resemblance to the little Jedi Master Yoda from the Star Wars films. But while Yoda has never demonstrated operatic skills, tarsiers are energetic singers who use vocals as a form of sexual selection, or signaling one another that it’s time for all members of a troupe to gather for sleep, according to a new study.
