Abstract

The role of growth factor Bmp4 during the evolution in the beak morphology of Darwin's finches on Galapagos Islands is discussed. The shifts in the heterochronic-timing of ontogenetic events and heterotopic-spatial expression of ontogenetic events result in evolutionary changes to the developmental program of large-versus small-beaked species of Darwin's finch.
