How would Darwin explain the emergence thick, strong beaks in birds living in an area with only hard shelled seeds? a) God designed the birds with thick beaks to allow them to easily break open the shells. b) When only shelled seeds are around, birds are constantly working their beaks to break these shells. Over time this strengthens their beaks. Birds that have strengthened beaks pass this trait on to their offspring. c) Birds with the thickest strongest beaks find the most food on these islands. Because they are well fed they survive, reproduce and pass on this trait. Birds with less strong beaks are less likely to survive. d) The birds need a thick strong beaks to break open shells so they made them over time.
