Is primate tool use special? Chimpanzee and New Caledonian crow compared
1Division of Biological Anthropology, Department of Archaeology and Anthropology, University of Cambridge, , Fitzwilliam Street, Cambridge CB21QH, UK.
Summary
Chimpanzees (Pan troglodytes) exhibit greater diversity in tool use and making than New Caledonian crows (Corvus moneduloides), particularly in complex behaviors beyond simple foraging. Further research is needed for a definitive comparison.
Area of Science:
- Primate behavior
- Avian cognition
- Comparative psychology
Background:
- Chimpanzees (Pan troglodytes) are recognized for their tool-making and use.
- New Caledonian crows (Corvus moneduloides) have recently been proposed as having equivalent or superior elementary technology.
- A systematic comparison is needed to evaluate these claims.
Purpose of the Study:
- To systematically compare chimpanzees and New Caledonian crows in their material culture.
- To analyze four specific aspects: associative technology, tool-making modes, tool-use modes, and tool-use functions.
- To focus on habitual tool use in natural settings.
Main Methods:
- Comparative analysis of tool use and making in chimpanzees and New Caledonian crows.
- Evaluation of four key aspects of material culture.
- Emphasis on naturalistic, habitual behaviors.
Main Results:
- Chimpanzees demonstrate greater variety in tool use and making compared to crows across all four assessed aspects.
- The differences are particularly pronounced in modes and functions extending beyond extractive foraging.
- Observed behaviors focused on habitual, natural tool use.
Conclusions:
- Chimpanzees display a more diverse material culture than New Caledonian crows, especially in complex tool use.
- While crows show advanced technology, the current data suggests chimpanzees are more versatile.
- Further extensive field research on crow behavior is necessary to conclusively determine the extent of their technological capabilities.

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
