Domestication effect of reduced brain size is reverted when mink become feral [PDF]
Royal Society Open Science, 2023 A typical consequence of breeding animal species for domestication is a reduction in relative brain size. When domesticated animals escape from captivity and establish feral populations, the larger brain of the wild phenotype is usually not regained.

The role of histone methyltransferases in neurocognitive disorders associated with brain size abnormalities [PDF]
Frontiers in Neuroscience, 2023 Brain size is controlled by several factors during neuronal development, including neural progenitor proliferation, neuronal arborization, gliogenesis, cell death, and synaptogenesis.

Evolution of Avian Eye Size Is Associated with Habitat Openness, Food Type and Brain Size [PDF]
Animals, 2023 The eye is the primary sensory organ that obtains information from the ecological environments and specifically bridges the brain with the extra environment.

Regulatory and coding sequences of TRNP1 co-evolve with brain size and cortical folding in mammals [PDF]
eLife, 2023 Brain size and cortical folding have increased and decreased recurrently during mammalian evolution. Identifying genetic elements whose sequence or functional properties co-evolve with these traits can provide unique information on evolutionary and ...

Little brainiacs and big dummies: Are we selecting for stupid, stout or small dogs? [PDF]
Open Veterinary Journal, 2021 Background: Brain size has been associated with intelligence of various orders and families of animals, leading to the concept of encephalization. Brain size scales with body weight between species within mammals to approximately the 0.67 power. However,

Large brain size is associated with low extra‐pair paternity across bird species
Ecology and Evolution, 2021 Background Gaining extrapair copulations (EPCs) is a complicated behavior process. The interaction between males and females to procure EPCs may be involved in brain function evolution and lead to a larger brain.

How hibernation in frogs drives brain and reproductive evolution in opposite directions
eLife, 2023 Environmental seasonality can promote the evolution of larger brains through cognitive and behavioral flexibility but can also hamper it when temporary food shortage is buffered by stored energy.

Interpopulational variation in human brain size: implications for hominin cognitive phylogeny
Anthropological Review, 2022 Throughout the hominin lineage brain size is believed to have increased threefold – increase which, it is argued by some researchers, results in the enhanced brain power that distinguishes humans from any other living being. However, as we demonstrate in

Brain size predicts learning abilities in bees
Royal Society Open Science, 2021 When it comes to the brain, bigger is generally considered better in terms of cognitive performance. While this notion is supported by studies of birds and primates showing that larger brains improve learning capacity, similar evidence is surprisingly ...
