SciLifeLab The Svedberg seminar series, Niclas Kolm, Brain Evolution
Monday April 3rd
Department of Zoology, Stockholm University
Niclas Kolm is Professor and head of the Ethology research program at Stockholm University. He uses a mix of field studies, phylogenetic comparative analyses and artificial selection experiments to study brain anatomy evolution and its consequences for behavior in a range of different vertebrates.
Brain size, predation and sexual selection
Brain size is enormously variable across the vertebrates and several hypotheses have been put forward to explain this variation. This talk will present some insights on brain evolution from comparative analyses and artificial selection on fishes. I will focus on the role of predation and sexual selection, two traits closely linked to fitness, in brain evolution. Based on examples from both phylogenetic comparative analyses and artificial selection experiments, I will argue that predation and sexual selection are highly important components in the evolution of more complex brains and behavior.
