Deskripsi
Islands may impose a distinct set of selective pressures, leading to the repeated evolution of certain traits. Here, Sayol et al. compare brain sizes of more than 1900 bird species in a phylogenetic context, finding a consistent trend for in situ evolution of increased brain size in island birds.
