How does consciousness vary across the animal kingdom? Are some animals 'more
conscious' than others? This article presents a multidimensional framework for …

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 …

the claim of consistent hemispheric specialisations across classes of chordates is
undermined by the absence of population-based directional asymmetry of paw/hand use in …

New Caledonian (NC) crows Corvus moneduloides are the most prolific avian tool users. In
the wild, they use at least three distinct tool types to extract invertebrate prey from deadwood …

Previous observations of a New Caledonian crow (Corvus moneduloides) spontaneously
bending wire and using it as a hook [Weir et al.(2002) Science 297: 981] have prompted …

Functional preferences in the use of right/left forelimbs are not exclusively present in
humans but have been widely documented in a variety of vertebrate and invertebrate …

We recorded preferential use of the left and right monocular visual field in black-winged
stilts, Himantopus himantopus, during predatory pecking and during courtship and mating …

Humans are expert tool users, who manipulate objects with dextrous hands and precise
visual control. Surprisingly, morphological predispositions, or adaptations, for tool use have …

Stan Coren's groundbreaking The Intelligence of Dogs meets Bernd Heinrich's classic Mind
