Close of Ayumu in laboratory \u003cbr/\u003eWhen it comes to laughter a study out today (4 June) shows that great apes and humans share a common ancestor that lived more than ten million years ago.\u003cbr/\u003eResearchers used tickling to make a variety of apes and some human babies laugh. \u003cbr/\u003eAfter analyzing the sounds, they concluded that the origin of laughter went far back in the evolutionary family tree.\u003cbr/\u003eThis gorilla was tickled - literally - to take part in the laughter research. \u003cbr/\u003eSince the Victorian era scientists have argued about the concept of natural selection and evolution. \u003cbr/\u003eBut now researchers say this playful scene reveals yet another extraordinary resemblance between ourselves and our furry cousins in the animal kingdom.\u003cbr/\u003eWe've all suspected that we may be related to the apes ever since the Victorians first began arguing over the concept of natural selection and evolution. \u003cbr/\u003eBut now scientists say this playful scene reveals yet another extraordinary resemblance between ourselves and our distant relatives in the animal kingdom.\u003cbr/\u003eThis gorilla, according to scientists, displays the same response that we do when we are tickled. \u003cbr/\u003eIt laughs. \u003cbr/\u003eApparently, that's how they signal it's playtime and not aggression. \u003cbr/\u003eIt doesn't sound much like human laughter, it's more like rapid panting, or slower noisy breathing or a short series of grunts. \u003cbr/\u003eDr Marina Davila Ross has spent years tickling and carefully documenting the behaviour of these apes and then making minutely detailed measurements of their vocal reactions. \u003cbr/\u003eThe noises were then compared to the chuckles made by human babies. \u003cbr/\u003eDavila Ross's study wasn't confined to gorillas. \u003cbr/\u003eShe's examined the traits of bonobos, orangutans and chimps as well. \u003cbr/\u003eShe says this has established evidence that primates are able to express positive emotions such as laughter, possibly even joy. \u003cbr/\u003eShe believes great apes and we ourselves inherited our propensity to laugh from a s hared ancestor that lived between ten and sixteen million years ago. \u003cbr/\u003eAlso that their emotional displays may possibly shed light on the ancestry and evolution of our own and more importantly, that our own speech and laughter may possibly have grown out of our primate roots. \u003cbr/\u003eAs far back as Charles Darwin, scientists have noted that apes make characteristic sounds during play or while being tickled. \u003cbr/\u003eDarwin himself was convinced that the apes he saw in London Zoo displayed expressions and emotions that were much the same as our own. \u003cbr/\u003eOne in particular caught his attention. \u003cbr/\u003eJenny the orangutan and a cast of her remains in London's Natural History Museum to this day. \u003cbr/\u003eApes like Jenny helped Darwin to draw comparisons between the state of emotions between animals and human beings. \u003cbr/\u003eDavila Ross says her studies at Germany's Institute of Veterinary Medicine and here at the UK's Portsmouth University have led her to discover an evolutionary tree of her own. \u003cbr/\u003eAfter measuring traits of each species' laughter sound, they mapped out how these sounds appeared to be related to each other. \u003cbr/\u003eThe result looked like a family tree which matched the way the species themselves are related. \u003cbr/\u003eShe also concluded that while human laughter isn't that similar to ape versions, its distinctive features could well have arisen from shared ancestral traits. \u003cbr/\u003eIt's not the first time we've discovered that we probably have more in common with our primate cousins than we initially suspected. \u003cbr/\u003eFive year old chimp Ayumu definitely had the last laugh in this 2007 Japanese study. \u003cbr/\u003eShe astonished scientists by out performing human adults in tests of short-term memory. \u003cbr/\u003eFor centuries humans have assumed that compared to other animals, we are superior in all areas of intellectual ability. \u003cbr/\u003eBut now it seem it's the chimps who laugh loudest. \u003cbr/\u003eKeyword animals wacky\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container
