of stickleback described to date • No detectable difference in trophic niche • Male sexual traits seem to be playing a key role in reproductive isolation
individuals • How predation affects brain evolution is likely highly context dependent – bigger not always better! • Selection experiments are a viable method for exploring the evolutionary ecology of the vertebrate brain
selection and/or gene flow • Find loci that are adaptively differentiated between each pair of populations • Quantify the degree of clustering of adaptive loci in the genome, controlling for mutation + gene density
