Four species of finch arrive on a newly formed galapagos island which is covered with cacti growing in loose, dry sand. the cacti have honey-filled flowers and tiny seeds. the theory of evolution by natural selection would probably predict that would most succesfully survive, because a) geospiza magnirostris; its large size makes it the fittest. b) geospiza fortis; it will probably be able to dig up worms with its bill. c) certhidia oliveacea; its tiny pointed bill is the best adapted to sip nectar. d) geospiza parvula; animals with intermediate traits tend to have higher survival rates in new places.
