- Based on data about brain size and body size in 120 families of birds, this study shows by means of path analysis that about 12% of within-family body size disparity can be explained by the average residual brain size within that family. Based on observations that brain size correlates with a number of cognitive measures, it is then concluded that behaviour might contribute to evolutionary diversification.
