Overall Brain Size, and Not Encephalization Quotient, Best Predicts Cognitive Ability across Non-Human Primates
TL;DR: This estimate of general cognitive ability across primates is not strongly correlated with neuroanatomical measures that statistically control for a possible effect of body size, such as encephalization quotient or brain size residuals, and there was no indication that neocortex-based measures were superior to measures based on the whole brain.
Journal ArticleDOI
Energetics and the evolution of human brain size
TL;DR: It is found that the size of brains and adipose depots are negatively correlated in mammals, indicating that encephalization and fat storage are compensatory strategies to buffer against starvation, however, these two strategies can be combined if fat storage does not unduly hamper locomotor efficiency.
Journal ArticleDOI
The Expensive Brain: a framework for explaining evolutionary changes in brain size.
Karin Isler,Carel P. van Schaik +1 more
TL;DR: The absence of a mammal-wide correlation between brain size and immature period argues against the Needing-to-Learn explanation for slower development among large brained mammals.
Journal ArticleDOI
Metabolic costs of brain size evolution
Karin Isler,Carel P. van Schaik +1 more
TL;DR: It is shown that in fact energetics is an issue in the maintenance of a relatively large brain, and that brain size is positively correlated with the BMR in mammals, controlling for body size effects, which concludes that attempts to explain brain size variation in different taxa must consider the ability to sustain the energy costs alongside cognitive benefits.
Journal ArticleDOI
Endocranial volumes of primate species: scaling analyses using a comprehensive and reliable data set
Karin Isler,E. Christopher Kirk,Joseph M. A. Miller,Gene A. Albrecht,Bruce R. Gelvin,Robert D. Martin +5 more
TL;DR: It is shown that basal metabolic rate (BMR) and gestation period are both positively correlated with brain size in primates, after controlling for the influence of body mass and potential effects of phylogenetic relatedness.
