Human brains are exceptionally large, support distinctive cognitive processes, and evolved
by natural selection to mediate adaptive behavior. Comparative biology situates the human …

Major evolutionary transitions can be triggered by behavioural novelty, and are often
associated with 'adaptive suites', which involve shifts in multiple co-adapted traits subject to …

The brain is an energetically costly organ that consumes a disproportionate amount of
resources. Species with larger brains relative to their body size have slower life histories …

Evidence of how gestational parameters evolved is essential to understanding this
fundamental stage of human life. Until now, these data seemed elusive given the skeletal …

Despite decades of research, much uncertainty remains regarding the selection pressures
responsible for brain size variation. Whilst the influential social brain hypothesis once …

Previous studies have demonstrated a correlation between longevity and brain size in a
variety of taxa. Little research has been devoted to understanding this link in parrots; yet …

Large brains provide adaptive cognitive benefits but require unusually high, near-constant
energy inputs and become fully functional well after their growth is completed …

A vast array of challenging environments are inhabited by mammals, such as living in
confined spaces where oxygen levels are likely to be low. Species can exhibit adaptations in …

Life history is a robust correlate of relative brain size: larger-brained mammals and birds
have slower life histories and longer lifespans than smaller-brained species. The cognitive …
