Referential gestural communication in wild chimpanzees (Pan troglodytes)

  journal={Current Biology},
Humans commonly use referential gestures, for example pointing, which direct the attention of recipients to particular aspects of the environment [1]. The use of these gestures has been linked with cognitive capacities such as mental state attribution [2,3] because the recipient must infer the signaler's meaning. In our closest living relatives, the non-human primates, referential gestures have been reported only in captive chimpanzees interacting with their human experimenters [4] and human…

Deictic gesturing in wild chimpanzees (Pan troglodytes)? Some possible cases.
4 cases of gestures by juvenile chimpanzees in the Sonso chimpanzee community in Budongo, Uganda, that, at some level, may appear to be deictic and referential are described and illustrated.

The present paper aims to provide a brief overview of the state of the art to encourage future research into the evolutionary origins and uses of referential gestural signaling.
Referential gestures are not ubiquitous in wild chimpanzee communities
Referential gestures such as pointing are ubiquitous in human societies and the production and comprehension of referential gestures requires many of the cognitive capacities also crucial for
Comprehension of iconic gestures by chimpanzees and human children.
Over time, chimpanzees learned to associate iconic gestures with the appropriate location faster than arbitrary gestures, suggesting at least some recognition of the iconicity involved.
Not here, there! Possible referential gesturing during allogrooming by wild bonnet macaques, Macaca radiata
This study documents here, for the first time, potentially referential gesturing, used intentionally as well, in a monkey species, the bonnet macaque Macaca radiata, in the wild, and adds to the growing evidence for early human language-like capacities in non-human species.
The heterochronic origins of explicit reference
Explicit reference is the communicative capacity to intentionally pick out a specific object in the environment and make that object a manifest topic for shared attention. Pointing is the
Gestures of apes and pre-linguistic human children: Similar or different?
The majority of studies on animal communication provide evidence that gestural signalling plays an important role in the communication of non-human primates and resembles that of pre-linguistic and
Cross-species referential signalling events in domestic dogs (Canis familiaris)
This study exposes impressive gesturing abilities in a non-primate mammal; especially when viewed in the context of the cross-species rather than intraspecific communication.
Spatial Reference in a Bonobo Gesture
This human uniqueness claim is revisited with a study of a previously undescribed human-like beckoning gesture in bonobos that has potentially both deictic and iconic character.
The use of referential gestures in ravens (Corvus corax) in the wild.
Evidence is reported that the use of declarative gestures is not restricted to the primate lineage and that these gestures may function as 'testing-signals' to evaluate the interest of a potential partner or to strengthen an already existing bond.


Referential communication by chimpanzees (Pan troglodytes).
The capacity for nonverbal reference may predate the Hominidae-Pongidae split, and the development of non verbal reference may be independent of human species-specific adaptations for speech.

Teaching sign language to a chimpanzee.
The protein encoded by Nup160 directly interacts with that of another hybrid lethality gene, Nup96, indicating that at least two lethal hybrid incompatibility genes have evolved as byproducts of divergent coevolution among interacting components of the Drosophila nuclear pore complex.
Some basic traits of language in wild chimpanzees
Communication between the mobile station and the TC center is in digital form and in particular in binary coded decimal form to provide said selected mobile station with collision avoidance, enroute navigation and approach data which data may be directly displayed on a digital display aboard said mobile station without any conversion of the data.
