Results (a) Comparison of the modes and magnitude of skull shape diversification in Darwin's finches and Hawaiian honeycreepers Morphometric analyses in which the more-inclusive landmark datasets were employed (using the final set of 15 landmarks which allows the extinct Hawaiian honeycreeper species to be analysed) on Darwin's finches, Hawaiian honeycreepers and their respective outgroups, reveal a highly significant degree of allometry ( p < 0.0001), which explains 12.6% of the variation in shape of the skull (electronic supplementary material, table S5).
