During some years, selection will favour those birds with larger beaks. Where the struggle for existence is fierce, the caltrop that is likeliest to succeed is the plant that puts more energy into spines and less into seeds; but in the safer, more secluded spot, the fittest plants are the ones that put more energy into making seeds and less energy into protecting them. [10] The lack of rain caused major food sources to become scarce, causing the need to find alternative food sources. Charles Darwin's experiences in the Galpagos Islands in 1835 helped to guide his thoughts toward a revolutionary theory: that species were not fixed but diversified from their ancestors over many generations, and that the driving mechanism of evolutionary change was natural selection.

One scenario is that the two species will merge into a single species combining gene variants from the two species, but perhaps a more likely scenario is that they will continue to behave as two species and either continue to exchange genes occasionally or develop reproductive isolation if the hybrids at some point show reduced fitness compared with purebred progeny. These birds provide a great way to study adaptive radiation. 1 (ma, Warehouse 13 Pete And Myka Kiss .
