Should we ban animal-tickling? Apparently not. AP reports that upon comparison, the sounds evoked by tickling three human babies and 21 orangutans, gorillas, chimps, and bonobos, all appeared to be the same thing: laughter. I would have protested, but since they didn’t scream, strike out, and feel unendurably queasy, I think we can let this one pass. (Judge for yourself – videos below.)Most importantly, researchers say the similarities suggest a common evolutionary origin, possibly back further than 10 million years. Other research has even shown a form of laughter in rats, and work continues outside the primate domain.
To see if they would cry, researchers fed the baby simians some red wine and showed them "The Notebook" starring Ryan Gosling.
