qq英文网名大全When the scientists t out to explore the roots of human laughter, some apes（类人猿） were just tickled（胳肢）to help. That’s how rearchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praid the work, it gives strong evidence that ape laughter and human laughter are related through evolution（进化）.
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate（灵长类动物） roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how the sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themlves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
type sPankpp, who studies laughter-like respons in animals but didn’t participate in the new work, called the paper exciting. Pankpp’s own work concludes that even rats produce laughter in respon to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.
