The human cerebral cortex is vastly expanded relative to other primates and
disproportionately occupied by distributed association regions. Here we offer a hypothesis …

Innovation is often assumed to be the work of a talented few, whose products are passed on
to the masses. Here, we argue that innovations are instead an emergent property of our …

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 …

A general model of neural development is derived to fit 18 mammalian species, including
humans, macaques, several rodent species, and six metatherian (marsupial) mammals. The …

In the last few million years, the hominin brain more than tripled in size. Comparisons across
evolutionary lineages suggest that this expansion may be part of a broader trend toward …

The question as to why primates have evolved unusually large brains has received much
attention, with many alternative proposals all supported by evidence. We review the main …

Comparative studies of the brain in mammals suggest that there are general architectural
principles governing its growth and evolutionary development. We are beginning to …

This chapter considers the functional utility of the prolonged period of immaturity in human
brain development. Development of the amygdala and its connections with the prefrontal …

Phenotypic traits are products of two processes: evolution and development. But how do
these processes combine to produce integrated phenotypes? Comparative studies identify …

The neuronal composition of the insula in primates displays a gradient, transitioning from
granular neocortex in the posterior-dorsal insula to agranular neocortex in the anterior …
