Brain size: a global or induced cost of learning?

EC Snell-Rood, DR Papaj, W Gronenberg - Brain, Behavior and …, 2009 - karger.com
The role of brain size as a cost of learning remains enigmatic; the nature and timing of such
costs is particularly uncertain. On one hand, comparative studies suggest that congenitally …

The costs of a big brain: extreme encephalization results in higher energetic demand and reduced hypoxia tolerance in weakly electric African fishes

KV Sukhum, MK Freiler, R Wang… - Proceedings of the …, 2016 - royalsocietypublishing.org
A large brain can offer several cognitive advantages. However, brain tissue has an
especially high metabolic rate. Thus, evolving an enlarged brain requires either a decrease …

Sperm competition and brain size evolution in mammals

JF Lemaître, SA Ramm, RA Barton… - Journal of evolutionary …, 2009 - academic.oup.com
The 'expensive tissue hypothesis' predicts a size trade‐off between the brain and other
energetically costly organs. A specific version of this hypothesis, the 'expensive sexual …

Allomaternal care, brains and fertility in mammals: who cares matters

SA Heldstab, K Isler, JM Burkart… - Behavioral Ecology and …, 2019 - Springer
The expensive brain hypothesis predicts that the lowest stable level of energy input sets the

Small organ size contributes to the slow pace of life in tropical birds

P Wiersma, B Nowak… - Journal of Experimental …, 2012 - journals.biologists.com
Attributes of an animal's life history, such as reproductive rate or longevity, typically fall along
a 'slow–fast'continuum. Animals at the fast end of this continuum, such as temperate birds …

Predator-driven brain size evolution in natural populations of Trinidadian killifish (Rivulus hartii)

MR Walsh, W Broyles, SM Beston… - Proceedings of the …, 2016 - royalsocietypublishing.org
Vertebrates exhibit extensive variation in relative brain size. It has long been assumed that
this variation is the product of ecologically driven natural selection. Yet, despite more than …
