Discussions of the evolution of intelligence have focused on monkeys and apes because of their close evolutionary relationship to humans. Other large-brained social animals, such as corvids, also understand their physical and social worlds. Here we review recent studies of tool manufacture, mental time travel, and social cognition in corvids, and suggest that complex cognition depends on a “tool kit” consisting of causal reasoning, flexibility, imagination, and prospection. Because corvids and… Expand
Convergent Evolution of Cognition in Corvids, Apes and Other Animals
TLDR
With the authors' expanding awareness of cognitive processes across species, attributes such as causal reasoning, mental time travel or mental attribution, once thought unique to humans, invite careful reconsideration of their evolutionary origins. Expand
Evolution of the avian brain and intelligence
TLDR
Western scrub-jays are the first non-human animals to demonstrate episodic-like memory — the ability to remember the ‘what, where and when’ of a specific past event, and this suggests that western scrub- jays may demonstrate another supposedly unique form of human cognition: theory of mind. Expand
Sociality, Evolution and Cognition
TLDR
Future research needs to get beyond vague ascription of 'greater intelligence' or 'faster learning' towards a precise account of the cognitive mechanisms that underlie particular mental skills in different species; that will allow theory-testing against data from complex, natural situations as well as from the laboratory, on a common metric. Expand
Social ecology of corvids
Recent behavioural studies in corvids (i.e. crows and jays) have demonstrated their sophisticated cognitive abilities such as mental-time travel, theory-of-mind-like ability, reasoning, and toolExpand
Social brains, simple minds: does social complexity really require cognitive complexity?
TLDR
This paper argues for greater attention to embodied and distributed theories of cognition, which get away from current fixations on ‘theory of mind’ and other high-level anthropocentric constructions, and allow for the generation of testable hypotheses that combine neurobiology, psychology and behaviour in a mutually reinforcing manner.

Cognitive ornithology: the evolution of avian intelligence
  • N. Emery
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2005
TLDR
This review discusses recent studies of avian cognition contrasting two different approaches; the anthropocentric approach and the adaptive specialization approach and suggests that complex cognition has evolved in species with very different brains through a process of convergent evolution rather than shared ancestry, although the notion that birds and mammals may share common neural connectivity patterns is discussed.

The Evolution of Mentalizing in Humans and Other Primates
Mentalizing, or theory of mind, is the ability to infer the mental states, such as desires and beliefs, that motivate others’ actions. Mentalizing is fundamental to human social life, underpinningExpand
Social cognition in ravens.

  • 2013
TLDR
It is argued that ravens represent a promising case for testing the idea that sophisticated social cognition may evolve in systems with a given degree of social complexity, independently of phylogeny. Expand
Convergent evolution of complex cognition: Insights from the field of avian cognition into the study of self-awareness
TLDR
The discussion of cognitive and metacognitive abilities in avian species is expanded, suggesting that an integrated assessment of these processes, together with revised and multiple tasks of mirror self-recognition, might shed light on one of the most highly debated topics in the literature—self-awareness in animals. Expand
Social Cognition and the Evolution of Language: Constructing Cognitive Phylogenies
TLDR
A broad comparative review of mechanisms underlying social intelligence in vertebrates is provided, with the goal of determining which human mechanisms are broadly shared, which have evolved in parallel in other clades, and which, potentially, are uniquely developed in the authors' species. Expand

TLDR
Evidence that convergent intelligence has occurred in two distantly related mammalian taxa is provided and these findings have important implications for understanding the generality and specificity of those processes that underlie cognition in different species and the nature of the evolution of intelligence.

Evolution of the brain and intelligence
TLDR
The outstanding intelligence of humans appears to result from a combination and enhancement of properties found in non-human primates, such as theory of mind, imitation and language, rather than from 'unique' properties. Expand

The social complexity hypothesis asserts that animals living in large social groups should display enhanced cognitive abilities along predictable dimensions. To test this concept, we compared highlyExpand

Mental time travel and the evolution of the human mind.
TLDR
It is argued that the human ability to travel mentally in time constitutes a discontinuity between ourselves and other animals and allows a more rapid and flexible adaptation to complex, changing environments than is afforded by instincts or conventional learning. Expand

A procedure that uses conditional discrimination training and transfer tests to determine whether chimpanzees have the concept "see" is proposed and critics are invited to identify flaws in the procedure and to suggest alternatives. Expand

  • 2000
TLDR
New evidence of human-like specialization in crows' manufacture of hook tools from pandanus leaves is found: functional lateralization or ‘handedness’ and the shaping of these tools to a rule system, the first demonstration that a population bias for handedness in tool-making and the shape of tools to rule systems are not concomitant with symbolic thought and language.

TLDR
The study confirms predicted trends linking opportunism, brain size and rate of structural evolution and suggests that innovation rate in the field may be a useful measure of behavioural plasticity. Expand
