Refer to the syllabus (section written assignments) for formatting instructions. 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. A research group led by Peter and Rosemary Grant of Princeton University has shown that a single year of drought on the islands can drive evolutionary changes in the finches.

This mating pattern is explained by the fact that Darwins finches imprint on the song of their fathers, so sons sing a song similar to their fathers song and daughters prefer to mate with males that sing like their fathers.
