Question 27

Bob v Ryan Bob believes that giraffes have long necks because they have stretched their necks over the course of their life while trying to reach food that is high in trees. Since the parent had stretched its neck during its life, it passed the long neck on to its offspring. Ryan believes that giraffes have long necks because the ones with longer necks were able to reach the food better than those with shorter necks. The longer necked giraffes had better survival rates and reproductive success, and soon all of the giraffes had long necks. Which of these 2 thinks like Darwin? Explain why
