Neural Processes Underlying Tool Use in Humans, Macaques, and Corvids
A possible neural network for tool use in macaques is suggested and it is hoped this might inspire research to discover a similar brain network in corvids and establish a framework to elucidate the neural mechanisms that supported the convergent evolution of toolUse in birds and mammals.
Tool Use in Animals: Insight, imagination and invention: Tool understanding in a non-tool-using corvid
This chapter discusses a series of experiments on a member of the corvid family of birds, rooks, to investigate what this species may have understood about how tools worked, what made a functional tool and even whether certain materials could be manipulated to make them into functional tools.
Did tool-use evolve with enhanced physical cognitive abilities?
It is predicted that the habitually tool-using species, New Caledonian crows and Galápagos woodpecker finches, should outperform their non-tool-using relatives, the small tree finches and the carrion crows in a physical problem but not in general learning tasks.
An Investigation of the Factors Driving Cognition in Darwin's finches
The data provide no evidence that tool-use in woodpecker has evolved in conjunction with enhanced physical cognition or that domain-specific experience hones domain- specific skills, an important contribution to a growing body of evidence indicating that animal tool- use, even that which seems complex, does not necessitate specialized cognitive adaptations.
Rooks perceive support relations similar to six-month-old babies
Evidence is presented that rooks hold certain expectations about how objects interact and appear to possess perceptual understanding of support relations similar to that demonstrated by human babies, which is more comprehensive than that of chimpanzees.

The chimpanzee (Pan troglodytes) is well-known in both nature and captivity as an impressive maker and user of tools, but recently the New Caledonian crow (Corvus moneduloides) has been championed as
Evolution of Cognitive Brains: Mammals
The number of cortical neurons appears to be a better predictor of intelligence but does not solve the paradox of elephants and cetaceans, which have at least several billion cortical neurons like the great apes, while being less intelligent.
How do adult humans compare with New Caledonian crows in tool selectivity?
The results showed that tool selection depended on the stimulus context (i.e., the number and lengths of the alternative tools) and the factors in addition to the candy’s distance influenced the participants’ selections.
T Tool Use
The challenges associated with longitudinal designs and correlational tests between tool use and individual fitness benefits make it extremely difficult to unequivocally demonstrate the adaptive value of tool use, as measured by increased survival rate and reproductive success.
Primate Social Cognition: Uniquely Primate, Uniquely Social, or Just Unique?

Primate Cognition
Of special importance, the human primate seems to possess a species-unique set of adaptations for "cultural intelligence," which are broad reaching in their effects on human cognition.

Methodological-conceptual problems in the study of chimpanzees’ folk physics: How studies with adult humans can help
The similarity of humans’ and chimpanzees’ behavior on these tasks highlights methodological and conceptual problems in studies of chimpanzees' folk physics and suggests alternative explanations for their behavior.
Tool selectivity in a non-primate, the New Caledonian crow (Corvus moneduloides)
An experiment is presented showing that New Caledonian crows are able to choose tools of the appropriate size for a novel task, without trial-and-error learning.
Chimpanzees fail to plan in an exchange task but succeed in a tool-using procedure
Self-control and tool use in tufted capuchin monkeys (Cebus apella).
The results indicate that capuchins are capable of delaying gratification when a higher quality reinforcer is present and that tool experience can influence levels of self-control in this task.
Transport of tools and mental representation: is capuchin monkey tool behaviour a useful model of Plio-Pleistocene hominid technology?
It is concluded that capuchin monkeys are a very inadequate source for modelling Plio-Pleistocene hominid's technological behaviour, and that the tool-using behaviour of capuchins presents no functional analogy with the tool behaviour of the Plio, Pleistocene and Denisovan hominids.
