چکیده

Humans are mainly right-handed for many actions including gestures. This bias is strongly linked to a left cerebral hemispheric dominance for language functions. Whether similar lateralized systems for communicative behaviors are present in other animals is unclear. Here we report the first evidence of strong population-level right-handedness in 60 captive baboons for a species-specific communicative manual gesture. Our findings support the view that lateralization for language may have evolved from a gestural system of communication controlled by the left hemisphere.

Human Infants and Baboons Show the Same Pattern of Handedness for a Communicative Gesture

To test the role of gestures in the origin of language, we studied hand preferences for grasping or pointing to objects at several spatial positions in human infants and adult baboons. If the roots of language are indeed in gestural communication, we expect that human infants and baboons will present a comparable difference in their pattern of laterality according to task: both should be more r...

Contrast of hand preferences between communicative gestures and non-communicative actions in baboons: implications for the origins of hemispheric specialization for language.

Gestural communication is a modality considered in the literature as a candidate for determining the ancestral prerequisites of the emergence of human language. As reported in captive chimpanzees and human children, a study in captive baboons revealed that a communicative gesture elicits stronger degree of right-hand bias than non-communicative actions. It remains unclear if it is the communica...

Hand preferences for unimanual and coordinated bimanual tasks in baboons (Papio anubis).

This study examined hand preference in baboons in a sample of 94 subjects for a unimanual task and in a sample of 104 subjects for a bimanual task. For the unimanual task, handedness was assessed by observing simple reaching for grains. For the bimanual task, tubes lined with peanut butter inside were presented to the baboons. The hand and the finger used to remove peanut butter were recorded. ...

The relative lengths and weights of metacarpals and metatarsals in baboons (papio hamadryas).

The lengths and weights of metacarpals and metatarsals were measured in two collections of baboon skeletons-33 animals, all born and raised in the wild, and 60 animals, nearly all born and raised in captivity. For both length and weight, ratios were constructed for all possible pairings of the five bones in each individual hand and foot. The pattern of results was not identical for the two coll...

Handedness and manual specialization in the baboon.

Manual preferences of six baboons were tested with three kinds of experimental tasks: (1) a simple reaching on a board or in a hole; (2) a box opening; (3) two visuo-spatial tasks requiring precise alignments of apertures. The distribution of right and left hand preferences was found to be symmetrical for the simple reachings (3 right- and 3 left-handers) and was consistent with the preferences...
