Which of the following best describes how LAMARCK would explain giraffes with long necks?
A. Long-necked giraffes eat more grass than short necked giraffes so their necks grow longer.
B. Natural variation in the population produces some longer and some shorter-necked giraffes and
longer necked giraffes can reach food more easily.
C. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on.
D. Giraffes just started out with long necks and haven’t changed.
On the Galapagos Islands, Darwin discovered birds with differently shaped beaks.
What might this tell you about the eating habits of the birds on different islands? Explain your answer.
