Abstract: | Comparative data on laterality of function in primates are useful for elucidating its evolution, including its link to asymmetry
of cerebral structure. Recently the gorilla (Gorilla gorilla, Pongidae) has been nominated as the other hominoid species closest toHomo sapiens in terms of handedness. This study aims to scrutinise the 22 accounts of gorillas' hand preferences. Numerous shortcomings
exist in the published literature on the topic, so that a firm conclusion is not yet possible. It is not yet clear whether
gorillas are right-preferent, left-preferent, or ambi-preferent, and additional data are needed. |
