Individual-level lateralisations are common among vertebrates, however population-level preferences are usually reserved for specific tasks. In humans, handedness is thought to be related to the hemispheric processing of specific aspects of language, including speech. Although nonhuman primates do not possess speech, gibbons are known to produce elaborate vocal displays often referred to as song. To investigate the evolutionary effects of singing on hand preference, this study examined leading… CONTINUE READING
