'Chimpanzees may have had their own "Stone Age," with evidence showing they were using stone tools to crack nuts 4,300 years ago, researchers reported on Monday.' 'They said the rocks are bigger and look different from the type typically used by early humans, but are the same type that are used by chimps today to crack nuts. And they are still coated with the crushed remains of nuts that appear to be some of the same varieties eaten today by chimps, but not humans.' 'The study adds to growing evidence that culture -- passing complex social information from one generation to the next -- is not unique to humans.' (full article on Reuters) | |
