Weirdest job? - 09/06/2009

Scientists have been researching the development of human laughter.  According to experts at Portsmouth University, human laughter can be traced back up to 16 million years ago to the last common ancestor of humans and apes.  

But how exactly did they work this out?  Simple - by tickling humans and apes and measuring the response. Apparently great apes use laughter to interact in a similar way to humans.  Now tickling a baby orangutan is one thing, but who'd volunteer to tickle a large male gorrilla?!
