Builds on the expensive tissue hypothesis proposed by Aiello & Wheeler (1995) and provides evidence that the maximum rate of population increase, as defined by Cole (1954), is correlated negatively with brain size in mammals and birds, as long as parental care is not provided (and thus the energetic costs of feeding borne) by the mothers alone. Predicts that such allomaternal care increases the "maximum viable brain size" in a given family and that brain size evolution is strongly coupled to mass extinction events.

Provides data indicating that the level of intelligence during child development correlates more closely with the rate of change of the cortical thickness than with cortical thickness itself.

  • From the Abstract: "Is there a biology of intelligence which is characteristic of the normal human nervous system?" Here we review 37 modern neuroimaging studies in an attempt to address this question...Reviewing studies from functional... and structural...neuroimaging paradigms, we report a striking consensus suggesting that variations in a distributed network predict individual differences found on intelligence and reasoning tasks. We describe this network as the Parieto-Frontal Integration Theory (P-FIT)...The P-FIT is examined in light of findings from human lesion studies...as well as findings from imaging research identifying brain regions under significant genetic control...We propose that the P-FIT provides a parsimonious account for many of the empirical observations, to date, which relate individual differences in intelligence test scores to variations in brain structure and function.

  • "While intelligence is one of the most talked about subjects within psychology, there is no standard definition of what exactly constitutes 'intelligence.' Some researchers have suggested that intelligence is a single, general ability, while other believe that intelligence encompasses a range of aptitudes, skills and talents."
