Cognition presents evolutionary research with one of its greatest challenges. Cognitive
evolution has been explained at the proximate level by shifts in absolute and relative brain …

Despite prolonged interest in comparing brain size and behavioral proxies of" intelligence"
across taxa, the adaptive and cognitive significance of brain size variation remains elusive …

As the brain is responsible for managing an individual's behavioral response to its
environment, we should expect that large relative brain size is an evolutionary response to …

Despite considerable current interest in the evolution of intelligence, the intuitively appealing
notion that brain volume and “intelligence” are linked remains untested. Here, we use …

Comparative studies have identified a wide range of behavioural and ecological correlates
of relative brain size, with results differing between taxonomic groups, and even within them …

The social brain hypothesis posits that social complexity is the primary driver of primate
cognitive complexity, and that social pressures ultimately led to the evolution of the large …

The mammalian brain is composed of numerous functionally distinct structures that vary in
size within and between clades, reflecting selection for sensory and cognitive specialization …

A persistent debate in behavioral research is whether brain size or architecture relates to
cognitive performance. A growing body of evidence has demonstrated correlations between …

Variations in brain size and proportions can be linked to the cognitive capacities of different
animal species, and correlations with ecology may give clues to the evolutionary origins of …

Although the social brain hypothesis has found near-universal acceptance as the best
explanation for the evolution of extensive variation in brain size among mammals, it faces …
