The emergence of music from the Theory of Mind (2009, background): “Thus, despite the divergent brain evolution of the two species, ToM evolved across primates and corvids as a result of convergent mental evolution due to similar socioecological challenges (Emery & Clayton, 2004).”
Darwin's mistake: Explaining the discontinuity between human and nonhuman minds (2008, neutral): “The best evidence for a ToM system in a non-primate comes from the work of Emery, Clayton and colleagues (Emery & Clayton 2001; 2004b; in press).”
Are bigger brains better? (2009, background): “This raises the question of whether absolute brain size plays any role at all in cognitive capacity — because both corvids and chimpanzees have similarly larger brains than expected for their body mass [110], they might have similar potential for intelligence [18].”
The Molecular Basis of Phenotypic Convergence (2014, background): “Today, studies of convergent evolution span most biological disciplines, from paleontology to cognitive science to molecular biology (e.g., Emery & Clayton 2004, Whittall et al. 2006, Zhou et al. 2008).”
Food sharing in jackdaws, Corvus monedula: what, why and with whom? (2006, background): “Emery & Clayton (2004) have argued that corvids (crows, jays, magpies and allies) may have similar levels of cognitive abilities to primates, but the food-sharing behaviour of corvids remains largely unexplored despite reports of it in several species (e.g. common ravens, C. corax: Heinrich 1988;…”
Mechanisms of reciprocity in primates: testing for short-term contingency of grooming and food sharing in bonobos and chimpanzees (2013, background): “However, astonishing dedicated cognitive specializations are found in 529 many organisms, for instance the incredible spatial memory, causal understanding of tools, and 530 understanding of others’ intentions in corvids (Emery & Clayton, 2004).”
Lasting recognition of threatening people by wild American crows (2010, background): “Crows have large brains with a well-developed hippocampus (Emery & Clayton 2004; Marzluff & Angell 2005), but the occurrence of an avian homologue to the mammalian amygdala is unresolved (Butler & Cotterill 2006).”
Evolution of the brain and intelligence. (2005, positive): “Corvid birds are astonishingly intelligent when it comes to tool use, flexibility and action planning, and may even rival primates in some respect [ 1 ].”
Evidence from four lemur species that ringtailed lemur social cognition converges with that of haplorhine primates (2011, positive): “Most notably, there is now growing evidence that some primates and corvid species are sensitive to the perceptual states of others (reviewed in: Emery & Clayton 2004; Call & Tomasello 2008; Rosati & Hare 2009).”
Intelligence in Corvids and Apes: A Case of Convergent Evolution? (2009, background): “Emery & Clayton (2004) pointed out that corvids, like apes, have evolved large brains relative to their body size, and that the areas of the brain thought to be functionally equivalent to the neocortex of primates, the nidopallium and mesopallium, are specifically enlarged.”
Domestic dogs are sensitive to a human's perspective (2009, background): “However, an alternative hypothesis and more likely explanation would be that the same mechanism is not involved for all species and are the result of convergent evolution (Emery & Clayton, 2004).”
Tool-related Cognition in New Caledonian Crows (2006, background): “…research, particularly in terms of long-term field studies that are necessary for putting experimental findings into an ecological and evolutionary perspective, so it would be premature to reach firm conclusions at this stage (a point also made by others, e.g., Emery, 2006; Emery & Clayton, 2004a).”
Finding new facts; thinking new thoughts. (2012, neutral): “…& Lobo, 2005; Brown, 1990; Gibson, 1977; Lockman, 2000; Norman, 1988, 1999) and other animals (Brauer, Kaminski, Reidel, Call, & Tomasello, 2006; Emery & Clayton, 2004; Hood, Carey, & Prasada, 2000; Mendes, Hanus, &Call, 2007; Stulp, Emery, Verhulst, &Clayton, 2009) learn to recognize the…”
Insightful problem solving and creative tool modification by captive nontool-using rooks (2009, background): “It appears more likely that corvid tool use is a useful by-product of a domain-general ‘‘cognitive tool-kit’’ (31) rather than a domain-specific ability that evolved to solve tool related problems.”
