Bangkok: The extra-marital monkey-business of men and women could be explained by studies on gibbons which are abandoning monogamy in favour of multiple partners, a Thai researcher said today.



Studies of gibbon species in Thailand, once known to mate for life, have shown the primates moving towards multiple partners due to changes in social structures and habitat pressures.



“We discovered there is a variation from monogamy to polygamy in densely populated gibbon areas,” Sompote Srikosamart, associate professor of biology at Thailand’s prestigious Mahidol University, told AFP.



“Gibbons are primates, and they are closely related to humans”, he explained.
