Deictic gesturing in wild chimpanzees (Pan troglodytes)? Some possible cases

Area of Science:

• Primate communication
• Comparative psychology
• Developmental linguistics

Background:

• Referential pointing is crucial for human language development.
• Great apes in captivity point for humans, but this is often seen as learned behavior.
• Spontaneous pointing in wild apes is rare, leading to doubts about their natural deictic abilities.

Observation:

• Four instances of apparent referential pointing gestures were observed in juvenile chimpanzees.
• These gestures occurred within the Sonso chimpanzee community in Budongo, Uganda.
• The observed gestures suggest a potential deictic and referential capacity in young chimpanzees.

Findings:

• The study presents evidence of spontaneous pointing in wild juvenile chimpanzees.
• These observations challenge the notion that referential pointing is exclusively a human trait.
• The findings suggest that great apes might possess a latent capacity for referential pointing.

Implications:

• This research could reshape our understanding of nonhuman primate cognition and communication.
• It prompts further investigation into the evolutionary origins of pointing and language.
• Understanding the reasons behind the infrequent use of pointing in chimpanzees is crucial for future studies.
