Divergence in brain size and brain region volumes across wild guppy populations.

Proceedings. Biological sciences - 31 Aug 2022

Abstract excerpt

Complex evolutionary dynamics have produced extensive variation in brain anatomy in the animal world. In guppies, Poecilia reticulata, brain size and anatomy have been extensively studied in the laboratory contributing to our understanding of brain evolution and the cognitive advantages that arise with brain anatomical variation. However, it is unclear whether these laboratory results can be translated to natural...
